Tropical Weather Outlook
NWS National Hurricane Center Miami FL
800 AM EDT Thu Sep 23 2021
For the North Atlantic...Caribbean Sea and the Gulf of Mexico:
The National Hurricane Center is issuing advisories on Tropical
Depression Eighteen, located about 1800 miles east-southeast of the
northern Leeward Islands.
The National Hurricane Center has issued the last advisory on
Post-Tropical Cyclone Rose, located more than 1300 miles
west-northwest of the Cabo Verde Islands.
A gale-force, non-tropical low pressure system, the remnants of
Odette, is located a little more than 600 miles west-northwest of
the westernmost Azores. While showers and thunderstorms remain
limited near the low, only a small increase in this activity could
result in the formation of a subtropical or tropical cyclone while
it moves generally southward over marginally warmer waters during
the next day or two. Strong upper-level winds are expected to
develop over the system by this weekend, which should then limit
further development. Additional information on this system,
including gale warnings, can be found in High Seas Forecasts issued
by the National Weather Service.
* Formation chance through 48 hours...medium...60 percent.
* Formation chance through 5 days...medium...60 percent.
Another tropical wave is expected to move off the west coast of
Africa by the end of the weekend. Thereafter, environmental
conditions are forecast to be conducive for gradual development of
this system as it moves westward at 10 to 15 mph over the far east
Atlantic.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...low...20 percent.

Perspectiva sobre las Condiciones del Tiempo en el Tropico
Centro Nacional de Huracanes del SNM Miami FL
Traducido por el SNM San Juan, PR
800 AM EDT jueves 23 de septiembre de 2021
Para el Atlantico Norte...Mar Caribe y Golfo de Mexico:
El Centro Nacional de Huracanes esta emitiendo advertencias sobre la
Depresion Tropical Dieciocho, localizada a unas 1800 millas al este
sureste de las Islas de Sotavento del norte.
El Centro Nacional de Huracanes ha emitido la ultima advertencia
sobre el Ciclon Pos-tropical Rose, localizado a mas de 1300 millas
al oeste noroeste de las Islas de Cabo Verde.
Un sistema de baja presion no tropical con fuerza de galerna, los
remanentes de Odette, se encuentra a poco mas de 600 millas al oeste
noroeste del extremo oeste de las Azores. Mientras que los aguaceros

Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1205 UTC Thu Sep 23 2021
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 31N. The following information is based on satellite
imagery, weather observations, radar and meteorological analysis.
Based on 0600 UTC surface analysis and satellite imagery through
1030 UTC.
...SPECIAL FEATURES...
Tropical Depression Eighteen is centered near 10.5N 36.4W at
23/0900 UTC or 1620 nm ESE of the Northern Leeward Islands
moving W at 13 kt. Estimated minimum central pressure is 1008
mb. Maximum sustained wind speed is 30 kt with gusts to 40 kt.
Convection is becoming better organized within 120 nm in the
northwest semicircle of the center of the depression. Seas are
estimate to be reaching 10 ft currently, but will build throughout
today within 120 nm on the north side of the low as it continues
to move westward. The depression is expected continue to intensify
and reach tropical storm strength later today, and likely become
a hurricane Sat. Please read the latest the latest NHC
Forecast/Advisory and Public Advisory for T.S. Eighteen at
www.hurricanes.gov for more details.
Recently downgraded Post-Tropical Cyclone Rose is centered
near 25.2N 41.6W at 23/0900 UTC or 1130 nm WNW of the Cabo Verde
Islands moving NW at 9 kt. Estimated minimum central pressure is
1010 mb. The center remains fully exposed with no significant
convection noted in its vicinity. An earlier CryoSat-2 altimeter
pass indicated seas were still reaching near 12 ft within 120 nm
in the northeast quadrant of Rose. This is not really due to the
winds near Rose, and is actually due to a larger area of northerly
swell causing 8 to 12 ft seas north of 22N between 35W and 60W.
Rose will move more north tonight, then northeast through Fri,
before gradually dissipating through Sat. Please read the latest the
latest Rose NHC Forecast/Advisory and Public Advisory at www.hurricanes.gov
for more details.
A gale-force, non-tropical low pressure system, the remnants of
Odette,is located about 520 nm west-northwest of the westernmost
Azores. While showers and thunderstorms remain limited near the
low, only a small increase in this activity could result in the
formation of a subtropical or tropical cyclone while it moves
generally southward over marginally warmer waters during the
next day or two. Strong upper-level winds are expected to
develop over the system by this weekend, which should then limit
further development. Additional information on this system,
including gale warnings, can be found in High Seas Forecasts
issued by the Ocean Prediction Center ocean.weather.gov. Also
see the latest Tropical Weather Outlook at www.hurricanes.gov
for more details.
...TROPICAL WAVES...
A tropical wave is evident just east of the Cabo Verde Islands
along 21W from 05N to 20N. Scattered moderate convection is noted
from 03N to 07N east of 22W. Another tropical wave is analyzed
along 50W/51W south of 20N. No significant convection is noted
near the wave axis.
...MONSOON TROUGH/ITCZ...
The monsoon trough passes through the the Senegalese coast near
15N17W to 08N25W to 08N30W. A segment of the ITCZ extends from
07N40W to 06N48W, and from 06N51W to 06N57W. Other than the
convection noted in the Tropical Wave section, no significant
convection is observed along the monsoon trough or in association
with the ITCZ.
GULF OF MEXICO...
An early season cold front is moving across the northern Gulf, and
currently extends from Crystal River, Florida to Poza Rica, Mexico.
Scatterometer satellite data along with recent buoy observations
indicate fresh to strong northerly winds are following the front.
This includes and area of fresh to strong NW winds just of the
Mexican coast near Tampico. Altimeter satellite data along with
recent buoy observations are showing seas building to 6 to 8 ft
behind the front. Light to gentle breezes and slight seas are
noted south of the front. Scattered moderate convection is noted
mainly along the coast of Mexico, south of 24N and west of 95W, as
well as a few thunderstorms along the front between 85W and 90W.
For the forecast, the front will continue to move southeastward
through tonight, stall from roughly Fort Myers, Florida to the
coast of Veracruz, Mexico near 18N95W Fri, then dissipate Sat.
Fresh to strong winds will follow the front into tonight,
including along the coast of Veracruz where seas may build to
8 ft. Looking ahead, winds and seas will diminish across basin
from Sat and into early next week as high pressure builds over
the northern Gulf.
CARIBBEAN SEA...
A sharp upper trough across eastern Cuba continues to support
scattered overnight showers and thunderstorms from the southern
peninsula of Haiti to Jamaica. Scattered showers and thunderstorms
are also evident north of the monsoon trough off the coast of
Colombia and eastern Panama. A weakened subtropical ridge north of
the area continues to support a pattern of below average winds
across the basin. Moderate trade winds are noted over the
southeast Caribbean, with generally light to gentle trade winds
elsewhere. Seas are 1 to 3 ft over the northwest Caribbean, and 3
to 5 ft elsewhere.
For the forecast, Tropical Depression Eighteen is well to the east near
10.5N 36.4W 1008 mb at 0900 UTC, moving W at 13 kt. Maximum
sustained winds are 30 kt with gusts 40 kt. Eighteen will will
continue to intensify as it moves across the Atlantic, becoming a
hurricane near 13N47W by Sat afternoon, and reaching 55W east of
the Leeward Islands by Mon. Marine interests in the Leeward
Islands should stay aware of the expected track of this developing
system. Meanwhile, moderate trade winds will persist over much of
the Caribbean into early next week, becoming fresh over the
south- central Caribbean starting Fri night as high pressure
builds east of the Bahamas.
ATLANTIC OCEAN...
Please read the Special Features section above for details on
the Tropical Depressions Rose and Eighteen.
The Cumbre Vieja volcano on the island of La Palma in the Canary
Islands has been erupting since 19/1410 UTC. The volcano is still
emitting ashes, mainly around the volcano drifting SSW below
10,000 ft, and NE above 10,000 ft. Marine and aviation interests
should monitor this on-going situation by reading Volcanic Ash
Advisory issued by Meteo-France at http://vaac.meteo.fr/volcanoes
/la-palma/. The next advisory will be issue no later than 23/0900
UTC.
A stationary front extends from 32N42W to 27N60W to 31N78W to low
pressure off the coast of South Carolina. An associated cold
front is moving off the Georgia and northeast Florida coasts,
reaching from the low pressure to near Jacksonville, Florida.
Scattered showers and a few thunderstorms are ongoing within 120
nm north of the stationary front between 60W and 65W. To the
south of the stationary front, the 1008 mb remnant low of Peter
persists near 22N67W. A large area of moderate to strong
convection is flaring from the center of the partially exposed
low, to within 90 nm of the center. A recent altimeter pass over
this low showed seas are at least seven feet, maybe eight, within
180 nm to the north of the center. This is due in part to
northerly swell that recently entered the area. Aside from the
features and related winds and seas already mentioned in this
discussion, moderate to occasionally fresh trade winds are noted
across the basing, with 4 to 6 ft seas in open waters.
For the forecast west of 65W, the remnant low of Peter will
dissipate as it drifts northeast of the region through Fri.
Meanwhile, the cold front moving off the northeast Florida coast
this morning will stall from 31N77W to near Fort Pierce, Florida
by tonight, then dissipate through early Sun just before a second
weak front possibly moves into the region early next week. Farther
east, Tropical Depression Eighteen will continue to intensify as
it moves across the Atlantic, becoming a hurricane near 13N47W by
Sat, and reaching 55W east of the Leeward Islands by Mon.

Marine Weather Discussion
NWS National Hurricane Center Miami FL
1122 AM EDT Mon May 17 2021
Marine Weather Discussion for the Gulf of Mexico, Caribbean Sea,
and Tropical North Atlantic from 07N to 19N between 55W and 64W
and the Southwest North Atlantic including the Bahamas
This is the last Marine Weather Discussion issued by the National
Hurricane Center. For marine information, please see the Tropical
Weather Discussion at: hurricanes.gov.
...GULF OF MEXICO...
High pressure along the middle Atlantic coasts extending SW to
the NE Gulf will remain generally stationary throughout the
week. This will support moderate to fresh E to SE winds over the
basin through Tue. Winds will increase to fresh to strong late
Tue through Fri as low pressure deepens across the Southern
Plains.
...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN
55W AND 64W...
A ridge NE of the Caribbean Sea will shift eastward and weaken,
diminishing winds and seas modestly through Wed. Trade winds
will increase basin wide Wed night through Fri night as high
pressure builds across the western Atlantic.
...SW N ATLANTIC INCLUDING THE BAHAMAS...
A weakening frontal boundary from 25N65W to the central Bahamas
