Cyclone Ockhi, which claimed 13 lives in Tamil Nadu and Kerala, has now moved beyond Lakshadweep, the weather department said bringing huge relief to the people of the rain-battered states.

However, many fishermen are still missing and warships have been deployed to comb the southeastern coast for fishing boats missing in wild seas.

Ockhi is now expected to travel north towards Mumbai and Gujarat in the next 48 hours, according to Indian Meteorological Department (IMD) Director S Sudevan in Thiruvananthapuram, though it is likely to lose intensity, reported news agency Reuters.

As many as 531 fishermen, stranded in the choppy waters off the Kerala and the Lakshadweep coasts due to Cyclone Ockhi, have been rescued, Kerala Chief Minister Pinarayi Vijayan said today. So far 393 people from Kerala have been rescued, Mr Vijayan said, as the state government announced a compensation of Rs. 10 lakh to the family of those who died in the storm.

Rescue operations are still on with Navy, Air Force and Coast Guard’s coordinated efforts in Thiruvananthapuram-Kollam coastal area. In Tamil Nadu, 60 fishermen are still missing and the Navy has been called in for their rescue
The Tamil Nadu government has also requested the centre to deploy helicopters of the Navy and the Coast Guard for the search and rescue efforts.” – NDTV (Reported by Sneha Mary Koshy, Edited by Soumyajit Majumder | Updated: December 02, 2017 20:26 IST)

Storm Brian

⚠️ Ireland and United Kingdom beware!

High winds and flooding as Storm Brian hits Ireland

Storm Brian has resulted in flooding and surface water in areas of the country that were among the worst hit by Storm Ophelia earlier this week. 

Limerick city has been hit by flooding after the River Shannon overflowed.

Limerick City and Council Council has tweeted images of flooding in front of Sarsfield House along Arthur’s Quay and the road at O’Callaghan Strand was also flooded.

The council said there are no reports of houses being flooded.

Flooding in Limerick later receded as water levels in the Shannon fell after the morning high tide.

In Galway city, temporary flood defences erected close to the Spanish Arch landmark proved effective, though the waters came close to reaching some properties.

There have been reports of flooding on roads in other south and west coastal areas.

Motorists are urged to drive with care as there is a lot of surface water on roads in Cork city and county, while conditions are said to be treacherous on the Bailick Road in Midleton.

The Ballyderown to Ballyduff Road is closed in Kilworth due to flooding.

In Co Kilkenny, the Bleach road and surrounding area are flooded.

Fallen trees and localised flooding have also been reported in Co Waterford.

Local authorities in counties Cork, Galway, Kerry and Kilkenny are among those dealing with the latest flooding which is not as severe as earlier in the week and this morning’s high tide around the Cork coast did not result in any flooding as had been feared.

Some localised spot flooding and trees down in a few locations this morning. Please travel with extreme care if you’re out

bbc-blocks-dark “Storm Brian has hit the UK with gale-force winds and high seas – though the weather is not as bad as predicted.

Gusts of over 70mph were recorded on Saturday morning, with forecasters warning of the potential for flooding, power cuts and transport disruption.

Yellow strong wind warnings are still in place across much of Wales, south England and the Midlands.

There are seven flood warnings across England, urging “immediate action”.

Seven flood warnings have also been issued for Wales.” BBC News

There are 6 Flood Warnings in Scotland

“The storm comes after three people were killed and hundreds of thousands of people – mostly in the Irish Republic – were left without power after the remnants of Storm Ophelia battered the British Isles after weakening from its earlier hurricane force.

Strong winds and high seas reached the western coast of Ireland overnight.

Gusts have hit 80mph (130km/h) in the country, said Irish weather agency Met Éireann, and flooding has been reported in some areas as the water level of the River Shannon rose.

The agency issued an orange warning – its second most severe alert – in seven Irish counties and advised motorists to take care, as trees weakened by Storm Ophelia could fall. However, it said the gusts “won’t be anywhere near as strong” as the previous storm.

A race meeting at Fairyhouse has been cancelled and the Cliffs of Moher tourist attraction in County Clare has been closed.

In Wales, trains and ferries have been cancelled and seafront roads closed.

The strongest wind gust has been measured in Mumbles, to the west of Swansea, at 71mph.

Natural Resources Wales said the coastline was likely to be “extremely dangerous this weekend” – with the Met Office predicting gusts of 60mph (96km/h) to 70mph (112km/h).

Tenby RNLI said it had launched its lifeboat to help a person in difficulty at Skrinkle, while Porthcawl RNLI warned people to watch the storm waves on its live feed, after people were spotted taking photographs from the harbour wall.

Ceredigion council has also warned people to “keep away” from seafronts and “be careful” on low-lying land where coastal flooding is possible.

The Met Office’s chief forecaster, Dan Suri, said gusts inland could also reach between 45mph (72km/h) and 55mph (88km/h).

In addition to the flood warnings, the Environment Agency has issued more than 40 flood alerts – meaning flooding is possible – most of which are in the west and south-west of England.

Flood barriers have been put in place in areas including Fowey in Cornwall, but Frank Newell, from the Environment Agency, said the surge had been lower than forecast.

“In terms of impact, we’ve had spray overtopping quaysides, but we don’t have at the moment any reported property flooding,” he said.

Across the UK, National Rail warned the weather could affect train services, with emergency speed restrictions imposed on most of the routes in Wales.

In England, South Western Railway has put a temporary speed restriction in place in both Hampshire and Dorset, and confirmed a tree had blocked the line between Fareham and Southampton – though this has now been cleared.

Speed restrictions are also operating on the Gatwick Express, Southern Rail and Thameslink, with some reduced services to ease congestion.

The Environment Agency’s national flood duty manager, Ben Lukey, warned people against posing for photos during the hazardous conditions.

He said: “We urge people to stay safe along the coast and warn against putting yourself in unnecessary danger by taking ‘storm selfies’ or driving through flood water – just 30cm (11in) is enough to move your car.”” – BBC News

YELLOW WARNING OF WIND for Wales, the Midlands, South West, South East, North West and Eastern England

Updated 09:05 on Fri 20th

Valid from 04:00 on Sat 21st to 23:59 on Sat 21st

A spell of strong winds is expected. Western and southern coastal transport routes and communities are likely to be affected by large waves and spray, with potential for flooding of properties. Some transport disruption is likely across the whole warning area, with delays to road, rail, air and ferry transport. Short term loss of power and other services is also possible, as well as damage to trees.

A swathe of strong south or southwesterly winds reaching parts of Wales and southwest England will steadily transfer east and north during the morning. Later in the afternoon winds will gradually turn westerly and wind inland will start to slowly ease. Meanwhile, in western and southern coastal areas winds will start to slowly ease later in the evening. Gusts of 45 to 55 mph are expected widely within the warning area with gusts of 60 to 70 mph along exposed southern and western coastal areas. These are expected to coincide with high tides, leading to locally dangerous conditions around coastal areas in western and southern parts of England and Wales.

(70 km/h). A turn toward the north-northeast with a decrease in
forward speed is expected on Monday, with that heading continuing
through Tuesday. On the forecast track, the center of the
post-tropical cyclone will move near western Ireland on Monday
and then near northern Scotland Monday night.

Maximum sustained winds are near 85 mph (140 km/h) with higher
gusts. Weakening is forecast during the next couple of days, and
the post-tropical cyclone is expected to dissipate near western
Norway by Tuesday night.

Hurricane-force winds extend outward up to 70 miles (110 km) from
the center, and tropical-storm-force winds extend outward up to 275
miles (445 km).

The estimated minimum central pressure is 969 mb (28.62 inches).

 

HAZARDS AFFECTING LAND
———————-
WIND: Gale-force winds are expected to begin across southern
Ireland during the next few hours and gradually spread northward
across the country during the day on Monday. Hurricane-force winds
are forecast to reach the southern portions of Ireland by Monday
afternoon. Strong winds will then spread across the remainder of
Ireland and parts of the United Kingdom into Monday night.
Preparations to protect lives and property should be complete.

Wind speeds atop and on the windward sides of hills and mountains
are often up to 30 percent stronger than the near-surface winds
indicated in this advisory, and in some elevated locations could be
even greater.

RAINFALL: Ophelia is expected to produce rainfall amounts of 2 to
3 inches (50 mm to 75 mm) with isolated totals near 4 inches (100
mm) through Tuesday across western Ireland and Scotland. Across
eastern Ireland, rainfall amounts will average around 1 inch (25 mm)
or less.

STORM SURGE: A dangerous storm surge is expected to produce
significant coastal flooding near and to the east of where the
center of the post-tropical cyclone makes landfall. Near the coast,
the surge will be accompanied by large and destructive waves.

Monday 16 October 2017

AMBER WARNING of WIND

for Northern Ireland, SW Scotland, West Wales, Isle Of Man

Between 12:00 Mon 16th and 23:00 Mon 16th

Updated Mon 16th October at 09:58

A spell of very windy weather is expected today in association with ex-Ophelia. Longer journey times and cancellations are likely, as road, rail, air and ferry services may be affected as well as some bridge closures. There is a good chance that power cuts may occur, with the potential to affect other services, such as mobile phone coverage. Flying debris is likely, such as tiles blown from roofs, as well as large waves around coastal districts with beach material being thrown onto coastal roads, sea fronts and properties. This leads to the potential for injuries and danger to life. This warning has been updated to extend it into parts of north and west Wales and into the extreme southwest of Scotland. The start time has been brought forward to 1200 to cater for southwest Wales but the impacts elsewhere are more likely later in the afternoon and into this evening.

Ex-Ophelia will move northwards across the west of Ireland today bringing some very strong winds to Northern Ireland along with parts of north and west Wales and the extreme southwest of Scotland. Gusts of 55-65 mph are expected widely with 80 mph gusts likely in places. A smaller area of very gusty winds is then likely to run across Northern Ireland from the west with 65-75 mph gusts possible for a short period of time in any one location. Winds are expected to peak across Northern Ireland and north and west Wales this afternoon including this evening’s busy travel period and to peak across southwest Scotland this evening.

YELLOW WARNING of WIND

for Central, Tayside & Fife Highlands & Eilean Siar North East England North West England Northern Ireland SW Scotland, Lothian Borders South West England Strathclyde Wales West Midlands Yorkshire & Humber

Between 10:00 Mon 16th and 23:55 Mon 16th October

Updated Mon 16th October at 10:33

Very strong winds are forecast to affect most western and some central parts of the UK during Monday. These strong winds are forecast in association with the northward track of ex-Ophelia across or near to the west of the British Isles. Southerly winds are most likely to gust between 55 and 65 mph across much of the warning area, especially in the west. There is also the potential for gusts of 80 mph in coastal areas, particularly on the eastern side of Northern Ireland as well as west Wales and the far southwest of Scotland. Please see separate amber warning. The very strong winds will probably extend to parts of northern England along with some southern and central parts of Scotland in the evening as winds veer more southwesterly across the whole warning area.

YELLOW WARNING of WIND for Scotland, Northern Ireland, Northwest and Northeast England.

Updated 13 October at 10:30

Valid from 00:05 on Tue 17th to 15:00 on Tue 17th

A spell of very windy weather is likely on Tuesday in association with ex-Ophelia. Road, rail, air and ferry services might be affected, with a slight chance of longer journeys times and some roads and bridges could close. There is a slight chance that power cuts may occur, with the potential to affect other services, such as mobile phone coverage. This warning has been updated to bring forward the end time slightly. The northward extent of the warning area across Scotland has been reduced but it has been extended slightly further south across Yorkshire.

There are no coastal watches or warnings in effect.

For storm information specific to your area, including possible
inland watches and warnings, please monitor products issued by your
local National Weather Service forecast office.

 

DISCUSSION AND 48-HOUR OUTLOOK
——————————
At 1000 AM CDT (1500 UTC), the center of Tropical Depression Nate
was located near latitude 33.1 North, longitude 87.3 West. The
depression is moving toward the north-northeast near 24 mph (39
km/h). A turn toward the northeast with an increase in forward
speed is expected during the next couple of days. On the forecast
track, Nate’s center will continue to move inland across the Deep
South, Tennessee Valley, and central Appalachian Mountains through
Monday.

Surface observations indicate that the maximum sustained winds have
decreased to near 35 mph (55 km/h) with higher gusts. Little change
in strength is predicted during the next couple of days, but Nate
is forecast to become post-tropical on Monday or Tuesday.

The estimated minimum central pressure is 996 mb (29.42 inches).

 

HAZARDS AFFECTING LAND
———————-
WIND: Tropical-storm-force wind gusts are expected over the
the Florida Panhandle, and portions of Alabama and Georgia through
this afternoon.

STORM SURGE: Water levels remain elevated along portions of the
northern Gulf coast, but should gradually subside this afternoon.

RAINFALL: Nate is expected to produce the following rain
accumulations through Monday:

East of the Mississippi River from the central Gulf Coast into the
Deep South, eastern Tennessee Valley, and southern Appalachians:
3 to 6 inches, max 10 inches.

Across the Ohio Valley into the central Appalachians:
2 to 5 inches, max 7 inches.

TORNADOES: A couple tornadoes will be possible today, mainly from
the Florida Panhandle and eastern Alabama across western and
northern Georgia into the western Carolinas.

SURF: Swells generated by Nate will affect land areas around the
Gulf of Mexico through this evening. These swells are likely
to cause life-threatening surf and rip current conditions. Please
consult products from your local weather office.

WATCHES AND WARNINGS
——————–
There are no coastal watches or warnings in effect.

 

DISCUSSION AND 48-HOUR OUTLOOK
——————————
At 1100 AM AST (1500 UTC), the center of Tropical Storm Maria was
located near latitude 36.8 North, longitude 69.3 West. Maria is
moving toward the east near 13 mph (20 km/h), and the storm is
expected to accelerate eastward through tonight. A turn back toward
the east-northeast with an additional increase in forward speed is
expected on Friday. On the forecast track, Maria will continue to
move away from the U.S. east coast and pass well to the south of
Atlantic Canada during the next couple of days.

Maximum sustained winds are near 70 mph (110 km/h) with higher
gusts. Some slight weakening is possible during the next 48 hours.

Tropical-storm-force winds extend outward up to 240 miles (390 km)
from the center.

The estimated minimum central pressure is 982 mb (29.00 inches).

 

HAZARDS AFFECTING LAND
———————-
SURF: Swells generated by Maria are affecting much of the east
coast of the United States, Atlantic Canada, and Bermuda. These
swells are likely to cause life-threatening surf and rip current
conditions. Please consult products from your local weather office
for more information.

Tropical Cyclone Information Statements

 

8:37 AM ADT Thursday 28 September 2017
Tropical cyclone information statement for:

Newfoundland and Labrador:

  • Avalon Peninsula Southeast

For Tropical Storm Maria.

The next information statement will be issued by 3:30 P.M. NDT.

Tropical Storm Maria currently east-northeast of Cape Hatteras, NC. Will accelerate eastward over next few days and track well offshore of Atlantic Canada.

1. Summary of basic information at 9.30 A.M. NDT.

Location: 36.7 north 69.8 west.

about 560 kilometres southeast of New York City.

Maximum sustained winds: 110 km/hour.

Present movement: east-northeast at 13 km/h.

Minimum central pressure: 982 mb.

2. Public weather impacts and warnings summary.

Maria is expected to track well offshore and not have any direct weather impacts on Canadian land areas. Periods of heavy rain are expected over parts of Atlantic Canada today from an unrelated frontal system approaching from the northwest.

a. Wind.

No direct wind impacts are expected over land from Maria as the strongest winds from the storm are expected to remain well offshore.

b. Rainfall.

Rain directly associated with Maria is expected to remain well offshore. However, moisture from the storm may feed into a cold front crossing Atlantic Canada today. This will enhance rainfall amounts along the front as it moves southward. The maximum level of enhancement may be over the southern Avalon Peninsula where a heavy rainfall warning is in effect. Once again, indirectly related to Maria.

c. Surge/waves.

There will be some ocean swells along the Atlantic coast of Nova Scotia today and tomorrow with waves breaking at times above 2 metres. Swells near 2 metres along the southern coast of Newfoundland will persist for a few days. These swells may build to 3-4 metres along the southern Avalon beginning tonight. Dangerous rip currents are also possible and the public should exercise caution until swells subside.

3. Marine weather impacts and warnings summary.

Maria could bring gales to the southern Grand Banks marine areas during its closest approach on Saturday. Seas (mostly swells) may build up to 5 metres over that area late Friday from a combination of both Maria and Hurricane Lee which is farther southeast.

Forecaster: Fogarty/March

Please continue to monitor alerts issued by the Canadian Hurricane Centre and forecasts issued by Environment Canada.

For more comprehensive information about track tables and forecast rationale, please see the Technical Discussion

UK: Storm Aileen to bring very strong winds across much of England and Wales during Tuesday night and into Wednesday morning – Published 12 Sep 2017 1425z (GMT/UTC)

windy 1825 BST

Image above: Windy.com – Near real-time interative wind map (Link)

Storm Aileen is the first storm to be named since this seasons names were released last week and it will bring strong winds to central parts of the UK.

A deepening area of low pressure will bring very strong winds across much of England and Wales during Tuesday night and into Wednesday morning. An Amber National Severe Weather Warning is in place, warning of gusts of 55-65 mph in particular across parts of Cheshire, Lancashire, Derbyshire, Yorkshire, Nottinghamshire and Lincolnshire.  Gusts up to around 75mph gusts could also be possible in exposed locations such as the coast and hills in these areas.

A Yellow weather warning for rain is also in place for parts of Northern Ireland, Northern England and Southern Scotland which warns of 30-40mm of rain falling within 6-9 hours which could cause some disruption.

Chief forecaster Frank Saunders said: “Storm Aileen is expected to bring strong winds of up to 75mph to a central segment of the UK and an Amber weather warning has been issued. As well as the strong winds, there will be some heavy rain pushing eastwards overnight which could see accumulations of 30-40mm. The low pressure system that is bringing these strong winds will move fairly swiftly from west to east over the UK and although there will still be some disruption through Wednesday morning, the winds will ease by the afternoon leaving a day of blustery showers.”

Richard Leonard, road safety spokesperson at Highways England, said: “We’re encouraging drivers to check the latest weather and travel conditions before setting off on journeys, with strong winds expected from Tuesday evening until Wednesday morning. In high winds, there’s a particular risk to lorries, caravans and motorbikes so we’d advise drivers of these vehicles to slow down and avoid using exposed sections of road if possible.”

There has been some speculation that this weather is being driven by the severe weather in the Caribbean and US. There is no such connection. Met Office Deputy Meteorologist Chris Tubbs said: “There are no links between the very strong winds we expect to see here in the UK and the hurricanes affecting the United States and the Caribbean at present. This system originated well north in the Atlantic Ocean, independent of the current Caribbean hurricanes”.

As Storm Aileen clears out eastwards into the North Sea, the UK will be left with cool showery conditions through the end of the week and into the weekend. The showers will still be blustery on Thursday with the winds easing as we get closer to the weekend. Within the showers there will be some periods of brightness although it will still feel cool across the whole of the UK with top temperatures only reaching 18-19°C

Storm Aileen will bring a brief spell of very strong westerly winds with gusts of 65-75 mph during the early hours of Wednesday. Longer journey times by road, rail and air are looking likely, with restrictions on roads and bridges. Damage to trees and perhaps buildings, as well as power cuts are expected. Flying debris and large coastal waves are possible, and these could lead to injuries.

YELLOW WARNING of WIND for Wales, The Midlands, southern parts of northern England, southwest England and southeast England.

Between 20:00 Tue 12th and 10:00 Wed 13th

The worst of the winds, with gusts to 65-75 mph, are expected to be across North Wales, southern parts of Northern England, the North Midlands and Norfolk, for which area a separate Amber warning is being issued. Longer journey times by road, rail and air are likely, with restrictions on roads and bridges. There is also a chance of power cuts, and damage to trees and perhaps buildings. Along windward-facing coasts, some wave overtopping is possible.

YELLOW WARNING of RAIN for southern parts of Northern Ireland, southern Scotland and northern England.

Between 17:00 Tue 12th and 08:00 Wed 13th

Heavy rain is expected later on Tuesday and early on Wednesday. This may cause flooding on the transport network, with spray and difficult driving conditions due to the combination of rain and wind. There is also a small chance of flooding affecting homes and businesses. Note also the possibility of strong winds in the south of the area – please see separate warnings.

inundation, from rising water moving inland from the coastline,
during the next 36 hours in the indicated locations. For a
depiction of areas at risk, please see the National Weather
Service Storm Surge Watch/Warning Graphic, available at
hurricanes.gov. This is a life-threatening situation. Persons
located within these areas should take all necessary actions to
protect life and property from rising water and the potential for
other dangerous conditions. Promptly follow evacuation and other
instructions from local officials.

Interests elsewhere in the southeastern United States should monitor

forecast track, the center of Irma will continue to move over
southwestern Georgia tonight and move into Alabama on Tuesday.

Maximum sustained winds have decreased to near 50 mph (85 km/h) with
higher gusts. Continued weakening is forecast, and Irma is likely
to become a tropical depression on Tuesday.

Tropical-storm-force winds extend outward up to 415 miles (665 km)
from the center.

The estimated minimum central pressure is 985 mb (29.09 inches).

 

HAZARDS AFFECTING LAND
———————-
STORM SURGE: The combination of a dangerous storm surge and the
tide will cause normally dry areas near the coast to be flooded by
rising waters moving inland from the shoreline. The water is
expected to reach the following HEIGHTS ABOVE GROUND if the peak
surge occurs at the time of high tide…

North of Clearwater Beach to Aucilla River…4 t 6 ft
West of Aucilla River to Ochlockonee River…1 to 3 ft
Clearwater Beach to Bonita Beach including Tampa Bay…1 to 3 ft

South Santee River to North of Fernandina Beach…4 to 6 ft
Fernandina Beach to Flagler/Volusia County line, including the St.
Johns River…1 to 3 ft

The deepest water will occur along the immediate coast in areas of
onshore winds, where the surge will be accompanied by large and
destructive waves. Surge-related flooding depends on the relative
timing of the surge and the tidal cycle, and can vary greatly over
short distances. For information specific to your area, please see
products issued by your local National Weather Service forecast
office.

WIND: Tropical storm conditions are expected in portions of the
warning area into tonight.

Rainfall: Irma is expected to produce the following rain
accumulations through Wednesday:

South Carolina and north-central Georgia and Alabama into the
southern Appalachians…3 to 6 inches with isolated 10 inches.
Northern Mississippi and southern portions of Tennessee and North
Carolina…2 to 4 inches.

TORNADOES: Isolated tornadoes are possible tonight along the South
Carolina coast.

SURF: Swells generated by Irma are affecting the southeast coast of
the United States. These swells are likely to cause life-
threatening surf and rip current conditions. Please consult
products from your local weather office.

SUMMARY OF WATCHES AND WARNINGS IN EFFECT:

A Hurricane Warning is in effect for…
* Cabo Rojo to Laguna Verde

A Tropical Storm Warning is in effect for…
* North of Cabo Rojo to Rio Panuco
* South of Laguna Verde to Puerto Veracruz

A Hurricane Warning means that hurricane conditions are expected
somewhere within the warning area, in this case within 12 to 24
hours. Preparations to protect life and property should be rushed
to completion.

A Tropical Storm Warning means that tropical storm conditions are
expected somewhere within the warning area, in this case within 24
hours.

For storm information specific to your area, please monitor
products issued by your national meteorological service.

 

DISCUSSION AND 48-HOUR OUTLOOK
——————————
At 1000 AM CDT (1500 UTC), the center of Hurricane Katia was located
near latitude 21.0 North, longitude 95.8 West. Katia is moving
toward the west-southwest near 5 mph (7 km/h) and this motion is
expected to continue through landfall within the hurricane warning
area early Saturday.

Maximum sustained winds are near 100 mph (155 km/h) with higher
gusts. Some additional strengthening is expected and Katia
could be near major hurricane strength at landfall.

Hurricane-force winds extend outward up to 25 miles (35 km) from the
center and tropical-storm-force winds extend outward up to 70 miles
(110 km).

The estimated minimum central pressure is 975 mb (28.80 inches).

 

HAZARDS AFFECTING LAND
———————-
STORM SURGE: A dangerous storm surge will raise water levels by
as much as 5 to 7 feet above normal tide levels near and to the
north of where Katia makes landfall. Near the coast, the surge will
be accompanied by large and destructive waves.

RAINFALL: Katia is expected to produce total rain accumulations of
10 to 15 inches over northern Veracruz, eastern Hidalgo, and
Puebla. Katia is also expected to produce total rain accumulations
of 2 to 5 inches over southern Tamaulipas, eastern San Luis Potosi,
western Hidalgo, eastern Queretaro, and southern Veracruz through
Saturday evening. Isolated maximum amounts of 25 inches are
possible in northern Veracruz, eastern Hidalgo, Puebla, and San
Luis Potosi. This rainfall will likely cause life-threatening flash
floods and mudslides, especially in areas of mountainous terrain.

WIND: Hurricane conditions are expected within portions of the
hurricane warning area by tonight or early Saturday, with tropical
storm conditions expected within the tropical storm warning areas by
later today.

SURF: Swells generated by Katia will continue to affect portions of
the coast of southeastern Mexico during the next couple of days.
These swells are likely to cause life-threatening surf and rip
current conditions. Please consult products from your local weather
office.

DISCUSSION AND 48-HOUR OUTLOOK
——————————
At 1000 PM CDT (0300 UTC), the center of Tropical Depression Harvey
was located near latitude 31.7 North, longitude 92.3 West. The
depression is moving toward the north-northeast near 9 mph (15 km/h)
and this motion is expected to continue tonight. A turn toward the
northeast is expected Thursday or Thursday night. On the forecast
track, the center of Harvey should move through central Louisiana
tonight, then move through northeastern Louisiana and northwestern
Mississippi Thursday and Thursday night, and over the Tennessee
Valley region on Friday.

Maximum sustained winds are near 35 mph (55 km/h) with higher gusts.
Gradual weakening is expected over the next 48 hours.

The estimated minimum central pressure is 998 mb (29.47 inches).

 

HAZARDS AFFECTING LAND
———————-
RAINFALL: Harvey is expected to produce additional rainfall
accumulations of 4 to 8 inches from southwestern Louisiana and the
adjacent border of eastern Texas northeastward into western
Tennessee and Kentucky through Friday with isolated amounts up to 12
inches. The threat of heavy rains has ended in the Houston/
Galveston area. However catastrophic and life-threatening flooding
will continue in and around Houston, Beaumont/Port Arthur,
and eastward into southwest Louisiana for the rest of the week. The
expected heavy rains spreading northeastward from Louisiana into
western Kentucky may also lead to flash flooding and increased river
and small stream flooding. DO NOT ATTEMPT TO TRAVEL IN THE AFFECTED
AREA IF YOU ARE IN A SAFE PLACE. DO NOT DRIVE INTO FLOODED
ROADWAYS. Please see warnings and products issued by your local
National Weather Service office for additional information on this
life-threatening situation.

Elsewhere, the outer bands of Harvey are expected to produce
additional rainfall amounts of 3 to 6 inches over portions of the
central and eastern Gulf States and 2 to 4 inches farther north into
parts of the Tennessee Valley, Ohio Valley and southern Mid Atlantic
through Saturday. These rains may lead to flooding concerns across
these areas.

A list of preliminary rainfall observations compiled by the NOAA
Weather Prediction Center can be found at:
http://www.wpc.ncep.noaa.gov/discussions/nfdscc1.html

STORM SURGE: Water levels along the northwestern and northern
Gulf coast should subside very slowly over the next day or two.

TORNADOES: Isolated tornadoes are possible tonight across parts of
Mississippi, southern Alabama, and southwest Georgia. Additional
tornadoes are possible on Thursday afternoon and evening across
northern portions of Mississippi, Alabama, Georgia, and into parts
of Tennessee.

within the watch area.

A Tropical Storm Warning means that tropical storm conditions are
expected somewhere within the warning area.

For storm information specific to your area, please monitor
products issued by your national meteorological service.

 

DISCUSSION AND 48-HOUR OUTLOOK
——————————
At 400 AM CDT (0900 UTC), the center of Tropical Storm Franklin was
located near latitude 20.4 North, longitude 92.7 West. Franklin is
moving toward the west near 13 mph (20 km/h) and this general motion
is expected to continue for the next 24 to 36 hours. On the
forecast track, the center of Franklin is expected to approach the
coast of eastern Mexico today, then cross the coast in the Mexican
state of Veracruz tonight or early Thursday.

Maximum sustained winds have increased to near 65 mph (100 km/h)
with higher gusts. Additional strengthening is expected, and
Franklin is forecast to become a hurricane later today and reach the
coast of Mexico as a hurricane tonight or early Thursday. Rapid
weakening is expected after landfall in Mexico.

Tropical-storm-force winds extend outward up to 140 miles (220 km)
from the center. The Mexican automated station at Cayo Arenas,
located to the north-northeast of the center, recently reported
sustained winds of 39 mph (63 km/h) and a wind gust of 51 mph
(81 km/h).

The estimated minimum central pressure is 994 mb (29.36 inches).

 

HAZARDS AFFECTING LAND
———————-
RAINFALL: Franklin is expected to produce additional rainfall
accumulations of 1 to 3 inches across portions of the Yucatan
Peninsula of Mexico through Monday. Rainfall totals of 4 to 8
inches with isolated maximum amounts of 15 inches are possible
across the Mexican states of Tabasco, northern Veracruz, northern
Puebla, Tlaxacala, Hidalgo, Queretar and eastern San Louis Potosi in
eastern Mexico. These rains will be capable of producing
life-threatening flash floods and mudslides.

WIND: Hurricane conditions are expected to reach the coast within
the Hurricane Warning area by tonight. Winds are expected to first
reach tropical storm strength later today, making outside
preparations difficult or dangerous. Preparations to protect life
and property should be rushed to completion.

Tropical storm conditions are expected across portions of the
Tropical Storm Warning area along the southern shore of the
Bay of Campeche through tonight. Hurricane conditions are
possible within the Hurricane Watch area tonight. Tropical storm
conditions are expected within the Tropical Storm Warning area in
eastern Mexico by this evening.

STORM SURGE: A dangerous storm surge will raise water levels by
as much as 2 to 4 feet above normal tide levels along the
immediate coast near and to the north of where the center makes
landfall in the Hurricane Warning area. Near the coast, the
surge will be accompanied by large and destructive waves.

Typhoon Noru poses a growing threat to southern Japan – Category 6

“Residents of Japan’s southern islands need to keep a close eye on Typhoon Noru. Noru was a strong Category 2 storm as of 12Z Tuesday, with top sustained winds (1-minute) of 90 knots (105 mph) as estimated by the Joint Typhoon Warning Center (JTWC). After hurtling to Category 5 intensity on Sunday, the typhoon weakened gradually on Monday as it lost the benefit of a high-altitude outflow channel. However, Noru is expected to re-intensify as it moves slowly northwest toward Japan, where it will encounter slightly warmer waters (above 30°C or 86°F), and into a region with more favorable upper-level winds.

Noru’s northwest track is expected to bend slightly westward as it moves around a compact upper-level high parked near South Korea and the Sea of Japan. This is good news for Japan’s key population centers, including Tokyo, as it would take the typhoon well to their southwest. The large southern island of Kyushu, and the smaller archipelago of the Ryukyu Islands, may not be so lucky. By this weekend, the JTWC track brings Noru toward the west coast of Kyushu as a Category 3 storm. Such a track would put Kyushu on the more dangerous right-hand side of the typhoon. The official three-day outlook from the Japan Meteorological Agency angles Noru more toward the west over the next three days, which would bring the strongest impacts into the more sparsely populated Ryukyu Islands. A crucial question is how quickly the small upper high to the north of Noru breaks down, which is very difficult to predict at this point. The cone of uncertainty for Noru is, in reality, larger than is currently being depicted, given the higher-than-usual uncertainties in the evolution of the steering flow for the typhoon.

For what it’s worth, the operational runs of both the European and GFS models re-intensify Noru into a fearsome super typhoon. The 0Z Tuesday run of the Euro model took Noru on a track similar to the JTWC forecast, looping just to the west of Kyushu, while the 0Z and 6Z Tuesday runs of the GFS moved Noru on a slower, more northward track that would affect Kyushu as well as parts of central Japan. Both models deepened Noru below 900 mb by this weekend, which would imply the possibility of a Category 5 supertyphoon, but these values are very likely unrealistic. This may be a good example of the current tendency of global models to over-deepen strong tropical cyclones at subtropical latitudes (roughly north of 25°N). Until recent years, the global models featured resolution that was too coarse to replicate the lowest pressures at the heart of strong tropical cyclones. Today, the upgraded, higher-resolution models can produce very low surface pressures more readily, but they do not fully account for the ocean-atmosphere interaction across subtropical regions. At these latitudes, late-summer ocean temperatures can be very warm over a very shallow layer that is quickly disrupted by a strong hurricane or typhoon. (Thanks to Julian Heming, UK Met Office, for this background.) We should look at the HWRF model, which is our best intensity model, for guidance on how strong Noru might get. The 06Z Tuesday run of the HWRF model rebuilds Noru to Category 4 strength with 140 mph winds, and predicts a track that would take the storm well west of Kyushu.” – Dr. Jeff Masters & Bob Henson atCategory 6

area. drizzle in Gulf Shores. light rain and LIFR in Fort Rucker
and Dothan. FLORIDA: rain, heavy at times, and LIFR conditions,
from Perry westward. LIFR/IFR around the Tampa/St. Petersburg
metropolitan area.

…THE CARIBBEAN SEA…

Upper level anticyclonic wind flow covers the area that is from
70W westward. Upper level cyclonic wind flow covers the rest of
the Caribbean Sea, with a 14N68W Caribbean Sea cyclonic
circulation center. Tropical Storm Bret is set to move into the
SE corner of the Caribbean Sea during the next 24 hours.

The Monsoon Trough extends from 09N74W in Colombia, through
Panama, northwestward through Costa Rica, and beyond, into the
eastern Pacific Ocean. Convective precipitation: isolated moderate
to locally strong is from 15N southward from 77W westward.

24-hour rainfall totals that are listed for the period that ended
at 20/0000 UTC…according to the PAN AMERICAN TEMPERATURE AND
PRECIPITATION TABLES…MIATPTPAN/SXCA01 KNHC…are 1.06 in
Guadeloupe, and 0.10 in Curacao.

…HISPANIOLA…

Middle level-to-upper level cyclonic wind flow, from an inverted
trough, is moving across the area. Rainshowers and thunder still
are possible across Hispaniola.

SURFACE OBSERVATIONS…for Port-au-Prince in Haiti: MVFR. for the
DOMINICAN REPUBLIC: Santo Domingo: VFR. few cumulonimbus clouds.
Punta Cana: rain and thunder. VFR. few cumulonimbus clouds.
Santiago: VFR. Puerto Plata: VFR.

The GFS MODEL forecast for 250 mb shows that day one will consist
of cyclonic wind flow, with the current N-to-S oriented trough.
Expect southerly wind flow during the first half of day two,
followed by anticyclonic wind flow during the second half of day
two. The GFS MODEL forecast for 500 mb shows that day one will
consist of the rest of the inverted trough moving through the area
completely, during day one. Day one will end with SE wind flow
moving across Hispaniola. Expect SE wind flow during day two, with
an E-to-W oriented Atlantic Ocean ridge. The GFS MODEL forecast
for 700 mb shows that day one will consist of SE-to-E wind flow.
Expect cyclonic wind flow with a separate inverted trough, during
day two. Hispaniola will be on the southern side of an E-to-W
oriented Atlantic Ocean ridge.

…THE ATLANTIC OCEAN…

An upper level trough is anchored by a cyclonic circulation
center that is about 770 nm to the NE of Puerto Rico, to a 14N68W
Caribbean Sea cyclonic circulation center. Convective
precipitation: widely scattered moderate to isolated strong from
20N to 21N between 68W and 70W. Broken to overcast multilayered
clouds and possible rainshowers are elsewhere from 22N southward
between Puerto Rico and 73W. Rainshowers and thunder still are

TROPICAL CYCLONE ADVICE NUMBER 15

Issued at 7:49 pm EST on Sunday 26 March 2017

Headline:

Tropical cyclone Debbie moving towards the coast, expected to intensify into a category 3 system this evening.

Areas Affected:

Warning Zone

Lucinda to St Lawrence including Townsville, Mackay, and the Whitsunday Islands.

Watch Zone

Innisfail to Lucinda, extending inland to Charters Towers and Mount Coolon.

Cancelled Zone

None.

Details of Tropical Cyclone Debbie at 7:00 pm AEST:

Intensity: Category 2, sustained winds near the centre of 110 kilometres per hour with wind gusts to 155 kilometres per hour.

Location: within 30 kilometres of 18.4 degrees South 150.9 degrees East, estimated to be 440 kilometres east northeast of Townsville and 330 kilometres east northeast of Bowen.

Movement: west southwest at 7 kilometres per hour.

Tropical cyclone Debbie is moving west-southwest towards the north Queensland coast and is currently forecast to intensify into a category 3 system tonight. Tropical cyclone Debbie is likely continue on a similar track and intensify further prior to making landfall between Rollingstone and Proserpine on Tuesday morning.

Hazards:

GALES are expected to develop about the exposed coast and islands between Ayr and Mackay tonight, and could extend to remaining areas between Lucinda and St Lawrence on Monday. GALES could extend further north to coastal areas between Innisfail and Lucinda during Monday evening or Tuesday morning, as well as further inland to Charters Towers and Mount Coolon.

DESTRUCTIVE WINDS with gusts over 125 km/h may develop about the exposed coast and islands between Ayr and Mackay as early as Monday morning. These DESTRUCTIVE WINDS may then gradually extend further north to Lucinda during the day Monday and overnight into Tuesday.

The VERY DESTRUCTIVE CORE of Tropical Cyclone Debbie is currently expected to cross the coast between Rollingstone and Proserpine on Tuesday morning, most likely as a CATEGORY 4 tropical cyclone, with wind gusts up to 260 km/h near the centre.

Abnormally high tides are expected to occur south of Proserpine on the high tides on Monday.

Residents between and between Lucinda and Mackay are specifically warned of the dangerous storm tide as the cyclone crosses the coast on Tuesday morning. The sea is likely to rise steadily up to a level well above the normal tide, with damaging waves and flooding of some low-lying areas close to the shoreline.as the cyclone approaches the coast on Tuesday. Large waves may also develop along the beachfront. People living in areas likely to be affected by this flooding should take measures to protect their property as much as possible and be prepared to follow instructions regarding evacuation of the area if advised to do so by the authorities.

Areas of heavy rain with the potential to cause severe flash flooding are expected to develop about parts of the northern and central Queensland coast and adjacent inland areas late on Sunday and continue through Monday and Tuesday. Widespread daily rainfall totals of 200 mm, with isolated falls of 400 mm, is also likely to lead to major river flooding over a broad area next week, and a Flood Watch is current for coastal catchments between Cardwell and Gladstone, extending inland to the eastern Gulf River catchments.

Recommended Action:

People between Ayr and St Lawrence should immediately commence or continue preparations, especially securing boats and property using available daylight hours.

– For cyclone preparedness and safety advice, visit Queensland’s Disaster Management Services website (www.disaster.qld.gov.au)

– For emergency assistance call the Queensland State Emergency Service on 132 500 (for assistance with storm damage, rising flood water, fallen trees on buildings or roof damage).

People between Cairns and Ayr, and inland to Charters Towers and Mount Coolon should consider what action they will need to take if the cyclone threat increases.

REMARKS:
260900Z POSITION NEAR 18.4S 151.0E.
TROPICAL CYCLONE 13P (DEBBIE), LOCATED APPROXIMATELY 320 NM EAST-
SOUTHEAST OF CAIRNS, AUSTRALIA, HAS TRACKED WEST-SOUTHWESTWARD AT
03 KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY DEPICTS AN ORGANIZED LOW-LEVEL CIRCULATION CENTER WITH
FLARING DEEP CONVECTION WRAPPING INTO THE SYSTEM. A 260545Z SSMIS 37
GHZ IMAGE REVEALS TIGHTLY CURVED CONVECTIVE BANDING, A LARGE
MICROWAVE EYE, AND SUPPORTS THE CURRENT JTWC BEST TRACK POSITION
WITH HIGH CONFIDENCE. THE INITIAL INTENSITY OF 70 KNOTS IS SUPPORTED
BY MULTI-AGENCY DVORAKS OF T3.5 (55 TO 70 KNOTS) LATEST SATCON
ESTIMATES AROUND 65 KNOTS, AND THE IMPROVED CONVECTIVE ORGANIZATION.
UPPER-LEVEL ANALYSIS CONTINUES TO INDICATE A VERY FAVORABLE
ENVIRONMENT FOR DEVELOPMENT WITH RADIAL OUTFLOW AND LOW VERTICAL
WIND SHEAR. HOWEVER, RECENT TPW IMAGERY SHOWS SOME DRY CONTINENTAL
AIR BEING ENTRAINED INTO THE SYSTEM, WHICH HAS SLOWED THE
INTENSIFICATION OVER THE PAST 12 HOURS. TC DEBBIE HAS BEEN TRACKING
SLOWLY SOUTHWESTWARD BETWEEN THE WESTERN PERIPHERY OF A NER AND A
STR TO THE SOUTHWEST. THIS SYSTEM WILL REMAIN UNDER THE SHARED
STEERING INFLUENCE OF BOTH FEATURES THROUGH THE FORECAST PERIOD,
WHICH WILL MAINTAIN ITS SOUTHWESTWARD TRAJECTORY. FAVORABLE
ENVIRONMENTAL CONDITIONS WILL PERSIST UNTIL TC 13P MAKES LANDFALL
SHORTLY AFTER TAU 36, ALLOWING FOR A PERIOD OF STEADY
INTENSIFICATION. AS THE SYSTEM TRACKS INLAND, THE FRICTIONAL EFFECTS
OF RUGGED TERRAIN WILL RAPIDLY ERODE THE CYCLONE LEADING TO COMPLETE
DISSIPATION BY THE END OF THE FORECAST PERIOD. DYNAMIC MODEL
GUIDANCE HAVE CONTINUED TO CONSOLIDATE ON THE FORECAST TRACK LENDING
HIGH CONFIDENCE TO THE JTWC FORECAST TRACK. MAXIMUM SIGNIFICANT WAVE
HEIGHT AT 260600Z IS 18 FEET. NEXT WARNINGS AT 262100Z AND 270900Z.//

REMARKS:
082100Z POSITION NEAR 15.2S 69.8E.
TROPICAL CYCLONE 11S (ELEVEN), LOCATED APPROXIMATELY 506 NM
SOUTH-SOUTHWEST OF DIEGO GARCIA, HAS TRACKED WESTWARD AT 05 KNOTS
OVER THE PAST SIX HOURS. ANIMATED INFRARED SATELLITE IMAGERY (IR)
AND A 081732Z AMSU 89 GHZ IMAGE DEPICT A PARTIALLY EXPOSED LOW-LEVEL
CIRCULATION CENTER (LLCC) WITH DEEP CONVECTION ALONG THE EASTERN
PERIPHERY. THE PREVIOUSLY FRAGMENTED CONVECTION HAS DEEPENED AND
CONSOLIDATED NEAR THE LLCC OVER THE LAST 6 TO 12 HOURS. THE INITIAL
POSITION IS SUPPORTED WITH HIGH CONFIDENCE BASED ON A 081732Z ASCAT
PASS SHOWING THE TIGHT LLCC. THE INITIAL INTENSITY OF 35 KNOTS IS
SUPPORTED BY THE RECENT ASCAT PASS SHOWING 35 KNOT WINDS ALONG THE
SOUTHERN PERIPHERY OF THE LLCC, AND DVORAK CURRENT INTENSITY
ESTIMATES RANGING FROM OF T2.5-3.0 FROM ALL REPORTING AGENCIES.
UPPER-LEVEL ANALYSIS INDICATES AN OVERALL FAVORABLE ENVIRONMENT FOR
DEVELOPMENT WITH A SMALL BUT DEVELOPING POINT SOURCE DIRECTLY OVER
THE SYSTEM, ACCOMPANIED BY LOW-MODERATE (15 TO 20 KNOTS) VERTICAL
WIND SHEAR (VWS). SSTS ALSO SUPPORT INTENSIFICATION WITH TEMPS
OBSERVED NEAR 30C. SINCE THE SYSTEM REMAINS RELATIVELY SHALLOW AT
THIS TIME, THE PRIMARY STEERING INFLUENCE IS THE SUB-TROPICAL RIDGE
(STR) TO THE SOUTH, STEERING TC 11S SOUTH OF DUE WEST FOR THE TIME
BEING. UPPER-LEVEL OUTFLOW FROM THE REMNANTS OF TC 09S ARE CURRENTLY
PROVIDING SOME PRESSURE ON THE WESTERN SIDE OF THE SYSTEM,
DISPLACING THE DEEPEST CONVECTION SLIGHTLY OFF THE LLCC, AND
LIMITING POTENTIAL INTENSIFICATION IN THE NEAR-TERM. THE SYSTEM IS
FORECAST TO UNDERGO SLOW INTENSIFICATION THROUGH TAU 24. AS UPPER-
LEVEL POLEWARD OUTFLOW IS REESTABLISHED BEYOND TAU 24, THE SYSTEM
WILL INTENSIFY AT A SLIGHTLY FASTER RATE, REACHING PEAK INTENSITY AT
TAU 120 AS THE SYSTEM WILL TAP INTO A STRONG POLEWARD OUTFLOW
CHANNEL AHEAD OF AN APPROACHING MID-LATITUDE TROUGH. TC11S WILL
TRACK GENERALLY WESTWARD THROUGH TAU 24 UNDER THE INFLUENCE OF THE
STEERING RIDGE TO THE SOUTH, THEN TURN SHARPLY SOUTHWEST AS IT
STRENGTHENS AND THE STEERING SHIFTS TO A NORTH-SOUTH ORIENTED RIDGE
TO THE EAST. TC 11S IS EXPECTED TO INCREASE IN FOREWORD MOTION AFTER
TAU 36 DUE TO THE STRENGTHENING OF THE RIDGE SYSTEM TO THE EAST.
DYNAMIC MODEL GUIDANCE REMAINS IN FAIRLY GOOD AGREEMENT ON THE
GENERAL DIRECTION OF THE TRACK, WITH SOME INITIAL DISAGREEMENT OF
THE TIMING OF THE TURN SOUTH. THE CURRENT FORECAST LIES NEAR THE
MULTI-MODEL CONSENSUS TRACK, LEADING TO HIGH CONFIDENCE IN THE JTWC
FORECAST TRACK. MAXIMUM SIGNIFICANT WAVE IS 14 FEET. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 081800Z IS 14 FEET. NEXT WARNINGS AT
090900Z AND 092100Z.//

THE SATELLITE PRESENTATION IS GENERALLY IMPROVING BUT IT IS
A VERY RECENT. THE N18 1416Z WATCH AGAIN PASS A CENTER EXPOSES A
WEST OF THE DEEP CONVECTION, AND IT IS SINCE SHORTLY BEFORE 17Z ONLY ONE
BURST OF CONVECTION TAKES PLACE VERY NEAR THE CENTER. THE ASCAT PASS OF THE
EVENING CONFIRMS INTENSITY ANALYZED. IF THIS TREND IS CONSOLIDATING
IN THE NEXT FEW HOURS, THE SYSTEM COULD TAKE ADVANTAGE OF THE SMALL
WINDOW OF FAVOURABLE CONDITIONS TO INTENSIFY MORE
SIGNIFICANTLY
THE MINIMUM SE MOVED SLOWLY IN THE WEST BRANCH UNDER
THE INFLUENCE OF THE SUBTROPICAL LOW/MEDIUM RIDGE
TROPOSPHERE LOCATED ON THE SOUTH EAST OF THE BASIN. TOMORROW NIGHT, THE
MODELS AVAILABLE ARE IN GOOD AGREEMENT TO PREDICT A TURN TOWARDS THE
SOUTH BUT WITH TIMING DIFFERENCES, WHICH CAUSES A
UNCERTAINTY AVERAGE WELL REPORTED BY THE DISPERSION OF THE FORECAST
OVERVIEW OF THE CEP. THIS WEEKEND, THE SYSTEM IS EXPECTED TO RECOVER HIS
PATH ON THE SIDE OF THE SUBTROPICAL RIDGE NORTHWEST AND
SPEED UP BYPASSING THIS RIDGE.
THE SMALL SIZE OF THE SYSTEM MAKES IT PARTICULARLY SENSITIVE HAS ITS
ENVIRONMENT, INCLUDING ALTITUDE, WHICH MAKES FORECASTING
HARD INTENSITY. FROM THURSDAY NIGHT, THE ASCENT OF A THALWEG
ALTITUDE FROM THE MIDDLE LATITUDES (WAVE SURGE OF)
ROSSBY) CAUSES THE APPEARANCE OF A SECTOR MODERATE CONSTRAINT
NORTH. ACCORDING TO THE LATEST MODEL DATA, MOVING
RELATIVELY QUICK OF THE SYSTEM COULD ALLOW IT TO LIMIT ITS
WITHIN THIS ENVIRONMENT LESS FAVOURABLE, WITHOUT WEAKENING
INFLUENCE ON BAROCLINIC NET DYNAMICS OF ALTITUDE. IN THE PROCESS OF
WEEKEND WITH THE DISSIPATION OF THE THALWEG OF ALTITUDE AND MAINTAINING
A GREAT DIFFERENCE POLAR, THE SYSTEM COULD BE

REINTENSIFIER.

LA PRESENTATION SATELLITE EST GLOBALEMENT EN AMELIORATION MAIS C’EST
TRES RECENT. LA PASS N18 DE 1416Z MONTRE ENCORE UN CENTRE EXPOSE A
L’OUEST DE LA CONVECTION PROFONDE, ET C’EST DEPUIS PEU AVANT 17Z QU’UN
BURST DE CONVECTION A LIEU TRES PRES DU CENTRE. LA PASS ASCAT DE LA
SOIREE CONFIRME L’INTENSITE ANALYSEE. SI CETTE TENDANCE SE CONSOLIDE
DANS LES PROCHAINES HEURES, LE SYSTEME POURRAIT PROFITER DE LA PETITE
FENETRE DE CONDITIONS FAVORABLES POUR S’INTENSIFIER PLUS
SIGNIFICATIVEMENT
LE MINIMUM SE DEPLACE LENTEMENT EN DIRECTION GENERALE DE L’OUEST SOUS
L’INFLUENCE DE LA DORSALE SUBTROPICALE DE BASSES/MOYENNES
TROPOSPHERE SITUEE SUR LA PARTIE SUD-EST DU BASSIN. DEMAIN SOIR, LES
MODELES DISPONIBLES SONT EN BON ACCORD POUR PREVOIR UN VIRAGE VERS LE
SUD MAIS AVEC DES DIFFERENCES DE TIMING, CE QUI PROVOQUE UNE
INCERTITUDE MOYENNE BIEN BALISEE PAR LA DISPERSION DE LA PREVISION
D’ENSEMBLE DU CEP. CE WEEK-END, LE SYSTEME DEVRAIT REDRESSER SA
TRAJECTOIRE SUR LA FACE NORD-OUEST DE LA DORSALE SUBTROPICALE ET
ACCELERER EN CONTOURNANT CETTE DORSALE.
LA PETITE TAILLE DU SYSTEME LE REND PARTICULIEREMENT SENSIBLE A SON
ENVIRONNEMENT, NOTAMMENT EN ALTITUDE, CE QUI REND LA PREVISION
D’INTENSITE DIFFICILE. A PARTIR DE JEUDI SOIR, LA REMONTEE D’UN THALWEG
D’ALTITUDE DEPUIS LES MOYENNES LATITUDES (DEFERLEMENT D’ONDE DE
ROSSBY) PROVOQUE L’APPARITION D’UNE CONTRAINTE MODEREE DE SECTEUR
NORD. SELON LES DERNIERES DONNEES MODELES, LE DEPLACEMENT
RELATIVEMENT RAPIDE DU SYSTEME POURRAIT LUI PERMETTRE DE LIMITER SON
AFFAIBLISSEMENT AU SEIN DE CET ENVIRONNEMENT MOINS FAVORABLE, SANS
INFLUENCE BAROCLINE NETTE DE LA DYNAMIQUE D’ALTITUDE. EN COURS DE
WEEK-END, AVEC LA DISSIPATION DU THALWEG D’ALTITUDE ET LE MAINTIEN
D’UNE EXCELLENTE DIVERGENCE POLAIRE, LE SYSTEME POURRAIT SE

ON THE LAST 6 HOURS. HE SHOULD DIVE MORE FRANKLY IN
HEADING SOUTH IN THE NEXT FEW HOURS IN ACCELERANT.
CONFIGURING SATELLITE REMAINS THE SAME, WITH THE PRESENCE OF
ACTIVE CONVERGENCE LINES (ESPECIALLY ON THE NORTH OF THE CHANNEL AND THE)
COAST NORTHWEST OF MADAGASCAR AT THE ELECTRICAL LEVEL) SE FAR FORMING
CENTER IN PART ON SEA IN THE NORTH-WEST QUADRANTS AND SOUTHEAST
THE TRAFFIC.
IN THE COMING DAYS, THE DISPLACEMENT CONTINUES ON A
TRAJECTORY THAT SHOULD QUICKLY BECOME MERIDIAN WITH THE WEAKENING
THE RIDGE PRESENT ON AVERAGE TROPOSPHERE ON MADAGASCAR. THE
ORDER OF THE WIND BLOW STRONG WINDS SHOULD REMAIN PRESENT THROUGHOUT
THE COAST IS MALAGASY DURING THIS DESCENT, IS EXTENDING TO THE SOUTHEAST
MALAGASY DURING THE DAY TOMORROW NIGHT OR NEXT. AT THE
RE-RELEASE AT SEA (THURSDAY NIGHT (A FRIDAY), THE BEGINNING OF A TRANSITION
EXTRATROPICAL SHOULD START QUICKLY ENOUGH IN INTERACTION
WITH A WATER-COURSE OF ARRIVING BY THE SOUTHWEST INTO A ALTITUDE
VERY CISAILLEE ENVIRONMENT WITH POTENTIAL OCEANIC
DECREASING QUICKLY.
