WATCHES AND WARNINGS
——————–
CHANGES WITH THIS ADVISORY:

The government of Mexico has extended the Tropical Storm Warning on
the west coast of the Baja California peninsula northward to San
Jose de Las Palomas, on the east coast northward to Isla San
Luis, and along the coast of mainland Mexico northward to Puerto
Libertad.

The government of Mexico has discontinued the Hurricane Watch for
Baja California Sur, as well as the Tropical Storm Warning south of
Altata on the coast of mainland Mexico.

SUMMARY OF WATCHES AND WARNINGS IN EFFECT:

A Tropical Storm Warning is in effect for…
* Baja California peninsula from San Jose de Las Palomas to Isla
San Luis
* Mainland Mexico from Altata to Puerto Libertad

A Tropical Storm Warning means that tropical storm conditions are
expected somewhere within the warning area within 36 hours.

Interests elsewhere in western Mexico and the Baja California
peninsula should monitor the progress of Lidia.

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

 

DISCUSSION AND 48-HOUR OUTLOOK
——————————
At 300 AM MDT (0900 UTC), the center of Tropical Storm Lidia was
located near latitude 23.8 North, longitude 111.0 West. Lidia is
moving toward the northwest near 8 mph (13 km/h), and this
direction with an increase in forward speed is expected through
Saturday night. On the forecast track, the center of Lidia will
move near or along the west coast of the Baja California peninsula
through Saturday and then move west of the peninsula over the
Pacific waters Saturday night.

Maximum sustained winds are near 65 mph (100 km/h) with higher
gusts. Weakening is forecast during the next couple of days while
Lidia interacts with the mountainous terrain of the Baja California
peninsula. Lidia is expected to become a remnant low by Saturday
night.

Tropical-storm-force winds extend outward up to 195 miles (315 km),
especially to the northeast and southeast of the center.

The estimated minimum central pressure is 987 mb (29.15 inches).

 

HAZARDS AFFECTING LAND
———————-
RAINFALL: Lidia is expected to produce total rain accumulations of
6 to 12 inches across the Mexican states of Baja California Sur into
Baja California, Sinaloa, and the coastal section of Sonora, with
isolated maximum amounts of 20 inches. These rains may cause
life-threatening flash floods and mudslides. Some of the tropical
moisture from Lidia may reach parts of the Desert Southwest this
holiday weekend, including southern California, southern Nevada, and
southwestern Arizona.

WIND: Tropical storm conditions are occurring over the southern
portion of Baja California Sur at this time. These conditions
should spread northward across the warning areas of the Baja
California peninsula and mainland Mexico through Saturday. 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.

STORM SURGE: A dangerous storm surge is expected to produce coastal
flooding in areas of onshore winds on the southern portion of Baja
California Sur. Near the coast, the surge will be accompanied by
large and destructive waves.

SURF: Swells generated by Lidia are affecting portions of the coast
of southwestern and western Mexico and southern portions of Baja
California Sur, and could cause life-threatening surf and rip
current conditions. Please consult products from your local weather
office.

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.
