Tropical Cyclone Information Statements

8:55 AM ADT Thursday 17 August 2017
Tropical cyclone information statement for:

Newfoundland and Labrador:

  • Newfoundland

For Hurricane Gert.

The next information statement will be issued by 3:30 p.m. NDT.

Hurricane Gert will race across the Southern Grand Banks today with no direct impacts to Canadian land areas. Hurricane force winds are not expected over the Grand Banks.

1. Summary of basic information at 09:30 a.m. NDT.

Location: Near 42.3 North 51.7 West.

About 497 kilometres south-southeast of Cape Race.

Maximum sustained winds: 148 kilometres per hour.

Present movement: East-northeast at 76 kilometres per hour.

Minimum central pressure: 972 millibars.

2. Public weather impacts and warnings summary.

A special weather statement highlights the possibility of abnormal variations in the tides.

a. Wind.

Any significant winds from Gert are expected to remain well offshore.

b. Rainfall.

Some moisture from Gert will feed into an approaching non-tropical weather system near eastern Newfoundland. This system will reach Newfoundland on Thursday and amounts of 25 to 50 mm are forecast over portions of eastern and northern Newfoundland.

c. Surge/Waves.

Long period swells from Gert will reach 2 to 4 metres along south-facing coastlines of Newfoundland later today, with the highest waves likely along the southern Avalon peninsula. These swells could also lead to dangerous rip currents. Significant wave heights of 3 to 5 metres are expected over the Grand Banks on this afternoon. The highest waves from Gert will remain south of Canadian waters.

In addition, Hurricane Gert may cause a series of rapid changes in water levels in harbours and inlets from the Avalon Peninsula north to Trinity Bay for a couple of hours. The most likely time ranges from late this afternoon into this evening. High tide will be occurring late this afternoon for most areas, so there is a risk for minor flooding near and after high tide.

3. Marine weather impacts and warnings summary.

The latest track for Gert has it passing over the extreme southern Grand Banks today and transitioning to a very intense mid-latitude storm as it passes east of our forecast waters. Gale to storm force winds are expected over southernmost portions of the Grand Banks, with hurricane force winds remaining just south of the Grand Banks. Gale and Storm warnings are in effect for the southern Grand Banks.

Forecaster(s): Mercer/Murtha/Couturier

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

Tropical Weather Discussion
NWS National Hurricane Center Miami FL
526 AM EDT Tue Aug 15 2017

Tropical Weather Discussion for North America, Central America
Gulf of Mexico, Caribbean Sea, northern sections of South
America, and Atlantic Ocean to the African coast from the
Equator to 32N. The following information is based on satellite
imagery, weather observations, radar and meteorological analysis.

Based on 0600 UTC surface analysis and satellite imagery through
0915 UTC.

…SPECIAL FEATURES…

Hurricane Gert is centered near 31.8N 72.5W at 15/0900 UTC or
about 375 nm W of Bermuda moving N at 11 kt. Estimated minimum
central pressure is 986 mb. Maximum sustained wind speed is 65 kt
with gusts to 80 kt. Numerous moderate to strong convection is
from 30N-32N between 70W-73W. Scattered moderate convection is
elsewhere from 28N-33N between 70W-74W. See latest NHC
forecast/advisory under AWIPS/WMO headers MIATCMAT3/WTNT23 KNHC
for more details.

…TROPICAL WAVES…

A tropical wave is W of the Cape Verde islands associated with a
1012 mb low pressure located near 14N28W. The wave axis extends
from 18N27W to the low to 09N28W and has been moving W at 10 kt.
The wave is in a region of low vertical wind shear, however
intrusion of Saharan dry air and dust to the wave environment
limit deep convection. Shallow moisture confined to the vicinity
of the monsoon trough and upper level diffluent wind support
scattered moderate convection SW of the low center from 10N-14N
between 28W-33W. Slow development of this system is anticipated
during the next day or two, but conditions are forecast to become
a little more conducive for tropical cyclone formation by later in
the week while the system moves westward over the tropical
Atlantic.

A tropical wave is in the central Atlc with axis extending from
20N51W to 09N53W, moving W at 25 kt. The wave is entering a
region of moderate to strong vertical wind shear and is being
severely affected by extensive Saharan dry air and dust, which is
hindering convection at the time.

A tropical wave is in the E Caribbean with axis extending from
20N64W to 10N66W, moving W at 25 kt. The wave is in a region of
strong vertical wind shear and dry air subsidence, which is
hindering deep convection at the time. Shallow moisture observed
in CIRA LPW imagery and upper level diffluent flow ahead of the
wave axis in the N-central Caribbean support isolated showers over
northern Puerto Rico and adjacent waters as well as the Mona
Passage and E Dominican Republic.

…ITCZ/MONSOON TROUGH…

The monsoon trough extends from the coast of W Africa near 12N16W
to 14N28W to 11N42W. The Intertropical Convergence Zone axis
extends from 11N43W to the coast of Venezuela near 09N60W.
Numerous heavy showers and scattered tstms are coming off the W
African coast associated with the next tropical wave. The
convection extends from 05N to 11N E of 18W. Scattered moderate
convection is from 06N to 15N between 34W and 46W associated with
a 1012 mb low located near 11N39W.

…DISCUSSION…

GULF OF MEXICO…

Weak surface ridging prevails across the basin, which along with
dry air subsidence support mainly fair weather conditions.
A broad upper level low is centered just N of the Yucatan
Peninsula, which supports isolated showers there and in the
Yucatan Channel. Diffluent flow in the NW periphery of the low
support similar shower activity off the SE coast of Louisiana and
Mississippi. Winds are gentle to moderate and from the S-SE in the
western half of the basin and light variable elsewhere. The ridge
will remain in place across the Gulf waters the next couple of
days. A surface trough will develop each evening across the
Yucatan Peninsula shifting W to the Bay of Campeche during the
overnight hours. Locally higher winds can be expected west of the
trough axis.

CARIBBEAN SEA…

A tropical wave is moving through the eastern Caribbean. Please
see section above. The tropical wave will continue to propagate
westward over Puerto Rico this morning, then will move over
central Caribbean waters tonight. Isolated showers are occurring
ahead of the wave axis over northern Puerto Rico and adjacent
waters, the Mona Passage and E Dominican Republic. This convection
is mainly due to shallow moisture and a diffluent wind environment
aloft associated with an upper level low over central Atlc waters.
A broad upper level low centered just N of the Yucatan Peninsula
support isolated showers in the Yucatan Channel extending to NW
Caribbean waters N of 17N W of 80W. Scattered heavy showers and
tstms are over Belize and northern Guatemala associated with the
passage of a tropical wave with axis currently moving across the
Gulf of Tehuantepec, Mexico. Otherwise, fresh to near gale force
winds are in the south-central basin forecast to continue through
Thursday.

…HISPANIOLA…

An upper level low over the central Atlc will drift WSW to the north
and across the Island over the next couple of days. This low aloft
along with the passage of a tropical wave will support scattered
to isolated showers over the Island and adjacent waters through
Thursday.

ATLANTIC OCEAN…

Scattered showers and tstms are N of 28N between 70W and 74W associated
with the rainbands of Hurricane Gert centered north of the area.
See Special features for further details. Otherwise, the
remainder basin generally N of 20N is under the influence of the
Azores high, which supports fair weather. For information about
tropical waves, see section above.

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

Cyclone Donna intensifies to Category 4

18:41 6 May 2017 (Local Time)

Taken from/By: FBC News
Report by: Akosita Talei

Severe Tropical Cyclone Donna has now intensified to a category four system with central pressure of 965 heta pascal destructive hurricane force winds estimated at about 90 knots close to the centre.

TC Donna was located 700km northwest of Port Vila or 1560km west-northwest of Nadi at mid-day today.

Fiji Meteorology Director Ravindra Kumar says it’s moving west-southwest at about 13km/hr and gradually turning southwards and expected to track towards New Caledonia and Southern Vanuatu.

He adds that although TC Donna still lies in favourable environment for further intensification, it’s expected to encounter unfavourable environmental conditions as it turns and tracks in a southerly direction.

He says Fiji is not directly threatened by TC Donna, however associated strong winds will affect Fiji waters and a strong wind warning remains in force for all Fiji waters.

Expect rough seas with east to southeast winds 20 to 25 knots, gusting to 30 knots.

Strong wind warning remains in force for all Fiji waters and Occasional showers expected. Isolated heavy rainfall may lead to flash flooding.
