DISCUSSION AND 48-HOUR OUTLOOK
——————————
At 500 PM EDT (2100 UTC), the center of Tropical Storm Philippe was
located by surface observations, radar data, and satellite images
near latitude 23.0 North, longitude 82.6 West. Philippe is moving
toward the north near 29 mph (46 km/h) and this motion is expected
to continue this evening, followed by a turn toward the northeast
by early Sunday morning. A faster motion toward the northeast is
expected on Sunday and continuing into Monday. On the forecast
track, the center of Philippe will move off of the northern coast
of Cuba and into the Straits of Florida this evening, and move
across the Florida Keys or the southern tip of the Florida peninsula
overnight, and across the northwestern Bahamas Sunday morning.

Maximum sustained winds have increased to near 40 mph (65 km/h) with
higher gusts. Additional strengthening is forecast during the next
48 hours.

Tropical-storm-force winds extend outward up to 105 miles (165 km)
mainly to the east and southeast of the center. A wind gust of 37
mph (59 km/h) was recently reported at Key West International
Airport.

The estimated minimum central pressure based on surface observations
is 1002 mb (29.59 inches).

 

HAZARDS AFFECTING LAND
———————-
RAINFALL: Philippe is expected to produce the following rainfall
totals:

The Cayman Islands, western and central Cuba, northern Bahamas:
4 to 8 inches with isolated maximum totals of 10 inches through
Sunday. These rainfall amounts may produce life threatening flash
floods and mudslides.

South Florida, including the Keys: 2 to 4 inches with isolated
maximum totals of 6 inches through Sunday. These rainfall totals
may produce flash flooding, especially in urbanized areas.

WIND: Tropical storm conditions are likely occurring in the
warning area across Cuba. Tropical storm conditions are expected to
occur in the warning area later tonight across the northwestern
Bahamas. Tropical storm conditions are possible across the upper
Florida Keys and southeast Florida overnight, and in the central
Bahamas by Sunday morning.

TORNADOES: A couple of brief tornadoes are possible across portions
of South Florida and the Florida Keys this afternoon and evening.

SUMMARY OF WATCHES AND WARNINGS IN EFFECT:

A Tropical Storm Warning is in effect for…
* Entire coast of El Salvador

A Tropical Storm Watch is in effect for…
* Pacific coast of Guatemala

A Tropical Storm Warning means that tropical storm conditions are
expected somewhere within the warning area, in this case within the
next 24 to 36 hours.

A Tropical Storm Watch means that tropical storm conditions are
possible within the watch area, in this case within the next 24
to 36 hours.

Interests in western Honduras should monitor the progress of Selma.

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

 

DISCUSSION AND 48-HOUR OUTLOOK
——————————
At 100 PM CDT (1800 UTC), the center of Tropical Storm Selma was
located near latitude 11.4 North, longitude 89.5 West. Selma is
moving toward the north-northwest near 5 mph (7 km/h), and the
cyclone is expected to turn toward the north by early Saturday.
On the forecast track, the center of Selma will approach the coast
of El Salvador or Guatemala on Saturday.

Maximum sustained winds are near 40 mph (65 km/h) with higher
gusts. Slight strengthening is forecast before Selma reaches the
coast of Central America.

Tropical-storm-force winds extend outward up to 45 miles (75 km)
from the center.

The estimated minimum central pressure is 1005 mb (29.68 inches).

 

HAZARDS AFFECTING LAND
———————-
RAINFALL: Selma is expected to produce total rain accumulations of
3 to 6 inches over El Salvador, southern Guatemala, southern
Honduras and far western Nicaragua over the next couple of days.
Isolated maximum amounts of 10 inches are possible in El Salvador
and southern Guatemala. This rainfall could cause life-threatening
flash floods and mudslides.

WIND: Tropical storm conditions are expected to first reach the
coast within the warning area by early Saturday, making outside
preparations difficult or dangerous. Tropical storm conditions
are possible within the watch area by early Saturday.

SURF: Swells generated by Selma are forecast to affect portions
of the coasts of Nicaragua, Honduras, El Salvador and Guatemala
later today. These swells are likely to cause life-threatening surf
and rip current conditions. Please consult products from your local
weather office.

Storm Brian batters Ireland and United Kingdom – Updated 21 Oct 2017 1507z (GMT/UTC)

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.

DISCUSSION AND 48-HOUR OUTLOOK
——————————
At 1100 PM AST (0300 UTC), the center of Post-Tropical Cyclone
Ophelia was located near latitude 49.2 North, longitude 13.3 West.
The post-tropical cyclone is moving toward the north near 44 mph
(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.

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.

MINIMUM CENTRAL PRESSURE…982 MB…29.00 INCHES

 

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.

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.

DEPICTS TIGHTLY CURVED BANDING CONTINUING TO SPIRAL INTO A DEFINED
LOW LEVEL CIRCULATION CENTER AS THE CYCLONE MOVES FURTHER INLAND
OVER MADAGASCAR. THE CONVECTIVE STRUCTURE HAS CONTINUED TO RAPIDLY
ERODE DUE TO THE LAND INTERACTION WITH THE RUGGED TERRAIN. THE
SYSTEM WILL TRACK SOUTHWARD ALONG THE WESTERN PERIPHERY OF THE
STEERING SUB-TROPICAL RIDGE TO THE EAST. CONCURRENTLY, TC 09S WILL
RAPIDLY DISSIPATE OVER THE NEXT 36 HOURS DUE TO THE IMPACTS OF THE
TERRAIN. THE REMNANT VORTEX SIGNATURE WILL BE ABSORBED INTO A MID-
LATITUDE CYCLONE PASSING SOUTH OF MADAGASCAR. DYNAMIC MODEL GUIDANCE
IS IN VERY TIGHT AGREEMENT LENDING HIGH CONFIDENCE TO THE JTWC
FORECAST. THIS IS THE FINAL WARNING ON THIS SYSTEM BY THE JOINT
TYPHOON WRNCEN PEARL HARBOR HI. THE SYSTEM WILL BE CLOSELY MONITORED

What is a ‘Spanish Plume’?

Official blog of the Met Office news team

There has been a lot of talk about warm weather expected across parts of England again this weekend.  Temperatures are forecast to reach the mid to high 20’s C on Friday and into the weekend, bringing the risk of thundery showers for some.  It has been reported that a ‘Spanish Plume’ is responsible for this. Here, Ewen McCallum, Met Office Chief Meteorologist explains what a ‘Spanish Plume’ is?

‘Spanish Plume’ is actually a rather catchy name for a rather complex meteorological phenomenon which leads to warm conditions and heavy showers or thunderstorms over parts of the UK and north-west Europe.

As the name suggests it is a plume of very warm air that pushes north from the Spanish plateau and reaches the British Isles on a southerly airflow.  Of course over the UK we are normally affected by much cooler Atlantic air as cold fronts encroach from the west. Now…

El Niño and its impact on global weather

Official blog of the Met Office news team

Forecast centres around the world have now declared that an El Niño, the most powerful fluctuation in our climate system, has begun in the tropical Pacific.

For more than a year, scientists have been talking of an increased risk of the start of El Niño conditions in the tropical Pacific.

Scientists have been watching closely because it can change the odds of floods, droughts, heat waves and cold seasons for different regions around the world and can even raise global temperatures.

Early signs of an El Niño last year failed to fully develop and atmospheric conditions remained close to neutral into the start of 2015.

Now, however, observations from the tropical Pacific show that we have moved to weak El Niño  conditions for the first time in five years.

While it is still too early to determine with confidence how strong this El Niño  might be forecast models from…

Europe: Severe weather inc tornadoes forecast for E France and S Germany (Estofex) – Published 250814 2215z (GMT/UTC)

European forecaster Estofex issues level 2 Storm Forecast for E France and S Germany…..

Storm Forecast

Forecast provided by ESTOFEX

Storm Forecast
Valid: Tue 26 Aug 2014 06:00 to Wed 27 Aug 2014 06:00 UTC
Issued: Mon 25 Aug 2014 21:17
Forecaster: SCHLENCZEK

A level 2 was issued for E France and S Germany mainly for tornadoes and severe wind gusts.

A level 1 was issued for NE/E France, Belgium, Luxembourg, S-central Germany and W Czech mainly for severe wind gusts and to a lesser extent for tornadoes.

A level 1 was issued for S UK for a chance of tornadoes.

A level 1 was issued for parts of the North Sea and Baltic Sea for spout-type tornadoes.

SYNOPSIS / DISCUSSION

… SE UK, NE / E France, SW / central Germany …

A dissipating low pressure system over the British Isles which continues eastwards advects warm and unstable air into W / central Europe. A few hundred J/kg of SBCAPE are forecast consistently in the warm sector by the past runs of GFS and ECMWF, at least partly overlapping with 15 – 25 m/s of 0-6 km bulk shear. T/Td is forecast around 20/16 °C for SW Germany which leads to low LCL heights. Convection should fire up in the late morning / early afternoon hours even though there is some subsidence over the central parts of Germany from the upper ridge. Combined with enhanced LL shear and SRH1, this may allow a few tornadoes. Further north, LL shear is weaker but the background wind field should be intense enough to support isolated severe wind gusts mainly from downward transfer of momentum. Local heavy precipitation is possible but fast storm motion should preclude a risk of flooding in most cases.

Over UK, there is very weak LL shear forecast in the afternoon hours but a weak background flow should support some spout-type tornadoes.

… N Germany, Denmark, N Poland, S Scandinavia and Baltic Sea region…

Sufficient buoyancy and weak background winds enhance the chance for long-lasting convergent flow in the vicinity of convective storms and may lead to funnels which could end up in spout-type tornadoes. The greatest chance for landspouts / waterspouts exists around Denmark and N Poland. Further north, deep layer shear is also quite weak but the stronger background flow will likely disturb the formation of funnels / tornadoes.

Some regions with locally enhanced LL shear exist over Finland but overall instability is likely too low to support a tornado threat covered by a LVL1.

… NW Italy and Mediterranean Sea…

A plume of unstable air is advected from the Balearic Islands towards Italy. It will likely remain strongly capped but in case of convective initiation, isolated storms may profit from 20 – 25 m/s of 0-6 km bulk shear and could develop mesocyclones. Overall threat is likely too marginal for a threat level as the capping inversion is likely too strong for storm development.

A TORRO TORNADO WATCH has been issued at 22:45GMT on Saturday 9th August 2014

Valid from/until: 03:00- 17:00GMT on Sunday 10th August 2014 for the following regions

Parts of (see map)

Much of southern, central, and eastern England, and parts of N England

Wales

Channel Islands

THREATS

Tornadoes; wind gusts to 60mph; CG lightning; hail

DISCUSSION

Deepening Atlantic storm with tropical airmass within its warm sector will cross the watch area during Sunday. Although the exact track is still somewhat uncertain, there are indications from several models that a dual-centred system will evolve. The first centre should move into Wales later tonight, with the main centre crossing SW England and heading NE to Lincs by afternoon, whilst the first centre tends to fill or is consumed by the second.

Strong lifting from a sharpening upper trough should steepen lapse rates enough for embedded convection to develop close to and to the south of both centres of low pressure, with wind shear favourable for severe weather, especially to the south and east of the second, deeper, low pressure area.

A mass of heavy rain is already moving in, and through the latter part of the night, embedded convection may affect parts of Wales and SW England, as the low pressure centre(s) move in. During Sunday morning, as the sharpening upper trough digs into the moist sector, it is possible that a squall line may develop across southern England/E Anglia. Additionally, ahead of the low pressure area moving from SW England to Lincs, convection may develop in the moist sector.

In each of these areas, low-level and deep layer wind shear appears sufficient for severe thunderstorms with strong winds and perhaps a tornado or two. The main caveat with this watch is that the maritime nature of the airmass would typically suggest fairly meagre lapse rates – however, global and mesoscale models indication fairly decent instability associated with this system (~1000J/Kg CAPE). If instability and shear can combine favourably, a strong tornado is possible.

The area from SW England to Lincs, and points south-east of there appear to have a higher risk of severe weather than elsewhere in the watch area. Please note this forecast has been issued early due to the fact the situation will not be monitored by TORRO overnight.

8 August 2014 – The remnants of Hurricane Bertha will continue to track towards the UK during the next few days.

“The Met Office has been assessing the likelihood of the UK seeing any effects from Bertha by using our own forecast models alongside models from other world-leading forecast centres.

At the moment southern parts of the UK look as though they are most at risk during Sunday, followed by areas of northeast Scotland on Monday. However, there is also the possibility that the depression could move across northern France as a weak feature.

Bertha storm tracks Possible storm tracks for ex Bertha on Sunday   Bertha Impacts Likely impacts from ex Bertha on Sunday

The transition of Bertha from a tropical to an extra-tropical feature is a particularly hard one to forecast but there is increasing confidence that this feature will affect the UK on Sunday, though with very large uncertainty remaining over the track and intensity.

Chief Meteorologist, Paul Gundersen, said: “There is still some uncertainty surrounding this weekend’s weather, with the potential for heavy rainfall, strong coastal winds and large waves on Sunday. However, there is still a chance that the system may pass to the south of the country giving the UK a brighter day.

“Rain and strong winds may well bring disruption, especially across southern parts of the UK, with the potential for more than 50 mm of rain and coastal gusts of over 60 mph. People should stay up to date with the latest Met Office warnings.”

Craig Woolhouse, Environment Agency Flood Risk Manager, said: “Heavy rain on Sunday may lead to localised surface water flooding in some parts of England and Wales. On Sunday and Monday a combination of high spring tides and strong westerly winds bring a risk of large waves and spray and possible flooding to the south west coast of England and along the Severn Estuary. However, the forecast remains uncertain so we advise people to regularly check the flood risk situation over the next few days.

“If you’re travelling to or from holiday then check your flood risk before setting off and don’t drive through flood waters.

“The Environment Agency is continuing to monitor the situation closely along with the Met Office and local authorities. People can sign up to receive free flood warnings, check their flood risk and keep up to date with the latest situation on the GOV.UK website to  check if you are at risk of flooding or follow @EnvAgency and #floodaware on Twitter for the latest flood updates.”

Jeremy Parr, Head of Flood Risk Management, Natural Resources Wales, said: “Our officers will be monitoring forecasts closely over the weekend as the situation in Wales becomes clearer but in the meantime we are advising people to remain alert.

“We are likely to see some very heavy rain on Sunday into Monday, and combined with strong winds and high spring tides, conditions along the coast could be dangerous.  As the forecast remains unsettled, we are advising people to keep an eye on weather forecasts and check the latest flood alerts on our website.”

Ross Macloed,  RNLI Coastal Safety Manager, said: “Extreme wave heights combined with high tides can make some normal coastal activities we take for granted significantly more risky; the force of surging water or breaking waves can easily knock you over and quickly drag you out of your depth and once in the water it can be difficult to get out. As little as one cubic metre of water weighs a tonne and shows that you should never underestimate how powerful the sea can be.

“If you are planning a coastal activity, our advice is to respect the water, and watch the shore from a safe distance and assess the conditions; think about the risk before deciding if  you need to go closer.”

Met Office records show that there are similar examples of intense low pressure systems occurring in August, for example, the 24 August 2005 where an active storm sat off the northwest coast of Scotland bringing strong winds and heavy rain. On the 30 August 1992 a depression swung up from the southwest across the UK giving a wet and windy Bank Holiday weekend.

We will be keeping an eye on the latest outlook for the weather over the next few days and the progress of ex Bertha to keep everyone up to date with the latest information.

Ex Bertha more likely to miss UK

 

Official blog of the Met Office news team

Tropical Storm Bertha is currently off the north east coast of the US and is likely to become an ‘extra tropical storm’ on Thursday.

It’s then expected to track across the Atlantic – and while there are still a number of possible outcomes, it looks increasingly likely that the UK will miss any serious impacts from ‘ex Bertha’.

The Met Office has been assessing the likelihood of the UK seeing any effects from Bertha by using our own forecast model alongside models from other world-leading forecast centres.

Map shows likely storm track for ex Bertha by midday Sunday. Map shows likely storm track for ex Bertha by midday Sunday.

At the moment the majority of forecasts from those models suggest ex Bertha will track to the south of the UK as a relatively weak low pressure system.

In fact it’s debatable whether this is even ex Bertha, as the storm declines to such an extent as it comes across the Atlantic…

France: Tornado kills 2 campers in Ardèche and Gard. 16 injured across Rhone-Alpes – Published 210714 1920z (UTC)

Two campers died when a tornado ripped through neighbouring campsites in Ardèche and Gard yesterday, on a weekend that saw much of France battered by storms.

A 50-year-old camper was killed when the tornado touched down at a campsite in Saint-Just d’Ardèche, causing trees to fall on dozens of tents. And a 46-year-old woman was fatally injured when the same tornado felled a tree at a site in Saint-Paulet-de-Caisson.

A total 40 campers were evacuated as the twister damaged a number of trees. The twin tragedies in Ardèche and Gard were caused as storms that swept across France passed through Cévennes and Nimes before returning to the Rhône Gard.

Elsewhere, hailstones the size of golf balls left 10 people injured and forced organisers to call a halt to a planned concert by Vanessa Paradis at the Grand Souk festival in Riberac, Dordogne, on Saturday.

Meanwhile, 1,000 jazz fans had to be evacuated from a festival concert in Saint-Emilion. Planned events on Sunday were also cancelled as volunteers cleared up after the storm.

Six scouts from Oise were taken to hospital in Gironde, on Saturday, after suffering lightning burns while on a camping trip in Saint-Simon de Pellouaille. Across Aquitaine, 8,500 households were left without power as storms swept through the region on Saturday night.

The tornado hit a campsite in the town of Saint-Just-d’Ardeche, pulling down trees and destroying caravans and tents on Sunday afternoon.

A 42-year-old Frenchman died when a tree fell on him as the tornado hit. Five others were left injured although their conditions are not believed to be life-threatening.

Captain François Degrange, from the local police told AFP that trees had been brought down over a three to four kilometer radius.

“I have never seen that in my career before,” he said.

In a separate incident a woman was also killed by a falling tree at a campsite at Saint-Paulet-de-Caisson in the neighbouring Gard department.

According to Midi-Libre newspaper a baby was also injured as the storms hit and had to be rushed to hospital.

Hundreds of campers in the region have had to be evacuated.

The storms, which brought the mini-heatwave to an abrupt end, were accompanied by gale force winds and hailstones the size of tennis balls in some regions.

Nine departments in eastern France remained on alert for storms on Sunday evening, while other areas of north eastern France were on alert for heavy rain and floods.

Europe: Euro-forecaster Estofex issues Level 2 Storm Forecast for N Italy – Published 290614 1700z

Storm Forecast

Forecast provided by ESTOFEX (Click image to go to source)

Storm Forecast
Valid: Sun 29 Jun 2014 06:00 to Mon 30 Jun 2014 06:00 UTC
Issued: Sun 29 Jun 2014 04:22
Forecaster: VAN DER VELDE

A level 2 was issued for N Italy mainly for severe convective wind gusts, large hail and excessive convective precipitation.

A level 1 was issued for parts of central Europe mainly for large hail.

SYNOPSIS

The cold front associated with a large amplitude mid level trough from Scandinavia to the Mediterranean Sea is pushing eastward through Italy and central Europe today. Surface level lows reside over southern Scandinavia and northern Italy. Cold airmass thunderstorms are likely over France, Benelux and western Germany. The prefrontal airmass over Italy is moderately unstable due to the presence of the Saharan Air Layer with steep mid level lapse rates and 10-12 g/kg moist boundary layer air. Strong winds in mid levels create a favorable kinematic environment for storms.

DISCUSSION

…Italy, southern Austria and western Balkan…

Some regional WRF models predict over 2500 J/kg SBCAPE over the Lgurian Sea. MLCAPE should be 1000-2000 J/kg. This will be capped south of the Po valley. Either way, given the 20 m/s deep layer shear and strong moisture lifting over the south slopes of the Alps triggering of supercells and MCSes is highly probable, with chances of widespread large to very large hail and severe wind gusts. During the evening as the cold front comes through, the model scenario (GFS, WRF) is that some discrete supercells or a linear system will also affect the area south of the Po valley. The area of Austria to Croatia will likely see the strongest moisture lift and largest storms, and can become affected by excessive convective rainfall, at least locally. The PV/dynamic tropopause intrusion acquires a negative tilt at night which might help to keep the storms active for long in the region near Slovenia, although WRF models keep the storms moving. Tornadoes are not ruled out with pre-Alpine 0-1 km shear of 8 m/s and locally higher.

…Hungary, N and E Austria, Czechia, Slovakia, Poland, Lithuania…

Relatively modest MLCAPE should exist in a broad area from Hungary/Austria to the Baltics. The presence of 10-15 m/s deep layer shear could develop persistent and rotating updrafts which can locally release large hail. The frontal convergence zone in the Austrian-Hungarian-Czechian borders region should be the main focus for convective development, another is NE Poland and Lithuania near the occlusion.

…southern Sweden and Norway…

Some instability is present within the low. Low cloud bases and slow cell motion combined with good low-level buoyancy and convergence zones are found mainly over southern Sweden. Such conditions are favorable for spout type tornadoes and funnels.

…France to Southwestern Germany…

A surface low pressure center lies currently (14Z) at the west coast of France (Bordeaux). A large Atlantic upper trough moves into the region and will provide destabilization of the mid and upper levels, which is needed as 12Z soundings still show inversions at 900 and 450 hPa. A stationary frontal zone is well-defined by thermal gradients and a sharp wind shift (NE/S) running from some 100km north of Bordeaux to Stuttgart approximately.

Observed surface mixing ratios in France vary at 13Z between 10.5 and 13 g/kg with potential temperatures ranging between 26 and 32ーC, the higher values over the Massif Central.
Inserting these values into Bordeaux and Nimes 12Z soundings, the cap can be bypassed in some locations and some 1000 J/kg SBCAPE could be obtained, but MLCAPE will be lower and mixed parcels may have some trouble with the cap.

In fact, satellite shows initiation over northern Massif Central oriented SW-NE and along the front in the west (WSW-ENE). The storms will grow in a strong kinematic environment with large but relatively straight hodographs. Observed Bordeaux 600 hPa wind is 60 kts with 40 kts at 900 hPa. This directly translates into a primary threat of severe convective wind gusts, especially as cold pools join into an MCS. Deep layer shear values of 15-20 m/s and SREH of 150 mイ/sイ initially and over 250 mイ/sイ predicted by GFS at 18Z (SW France) support supercells. 0-1 km shear ranges from 10 m/s in the afternoon to over 15 m/s during the evening (GFS). Together with relatively low LCL (descending to <1000 m in the evening) this underlines potential for tornadoes, and supports bow echoes. Large hail will be possible as well, but the upper level inversion represents a mixed phase region without much buoyancy which could be a limiting factor.

After 18Z the mid level cold front comes in from the west and will likely trigger storms in SW France moving upscale to a somewhat parallel-stratiform MCS over the southeastern quarter of France (this will happen beyond the validity time of this MD).

Hagibis re-intensifies near Japan, What to Expect – WestPacWx

Tropical Storm Hagibis is acting like that annoying little person you know that will just not go away. This storm formed quickly in the south china sea, came on shore Sunday, weakened over China and then made a return from the grave Tuesday morning in the East China Sea as a Tropical Storm yet again with winds sustained at 65kph and pressure at 996hpa.

In reality though this storm really is sub-tropical at this point. The bulk of the convection remains along the western side of the storm with dry air wrapping in from the north on the east. Furthermore it has an abundance of upper level support shearing apart the low level circulation.  Still though it will pack a 1-2 punch with the rain season front in western Japan.

VIS SAT

Specifically southern Kyushu heavy rainfall up to 200mm is expected through Wednesday morning along with high winds and large waves near the coastline.

The storm is racing north of Okinawa today but a few thunderstorms are still possible on what would be a cold front developing south of the storm. A few of these could become strong. The biggest problem in Okinawa though will be the gusty winds and high waves from the North.

Hagibis will continue to track east south of Tokyo but still will bring high waves up and down the pacific coast of Japan as a strong extra-tropical storm.

Farther North in Japan what we are seeing is a cut off low proving to be the ignition for severe thunderstorms on Tuesday and Wednesday in Central and Northern Japan. Cold upper level air combined with day time heating could trigger more severe weather.

I say more because on Monday a storm brought heavy rainfall and hail to Tochigi prefecture. In Utsunomiya flooding was reported along with landslides causing 30 families to be evacuated and nine homes were inundated by flood waters.

In Eastern China is still expected mostly due to the rainy season front. Flooding is still possible in areas south of the Yangzi river basin.

The monsoon continues to settle farther south but later this week we could see another surge from the south west. Check the latest update for more information on this..
