Tropical Weather Discussion for North America, Central America
Gulf of America, 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 0000 UTC surface analysis and satellite imagery through
0400 UTC.
...SPECIAL FEATURES...
Post-Tropical Cyclone Gonzalo is centered near 19.6N 23.2W at
27/0000 UTC, moving NNW at 7 kt. Estimated minimum central
pressure is 1008 mb. Maximum sustained winds are 35 kt within 90
nm across the NE semicircle. Peak seas are near 16 ft in the NE
quadrant. Gonzalo remnants are a sheared system with scattered to
locally numerous moderate isolated strong convection extending
well NE of the center, from 19.5N to 24N between 16W and 23W. The
remnant low of Gonzalo will continue to move N-NW and away from
the Cabo Verde Islands during the next few days, while gradually
weakening. S to SE swell generated by Gonzalo and the regional
monsoonal winds are expected to continue to affect portions of the
Cabo Verde Islands overnight while gradually diminishing through
Sunday morning.
Please read the latest area forecasts for the Post-Tropical
remnants of Gonzalo issued by MeteoFrance at
wwmis.wmo.int/index.php/metareas/display/2 for more details.
...TROPICAL WAVES...
A tropical wave is analyzed along 66W, south of 18N, moving west
at 10 to 15 kt. The wave has become significantly sheared by an
upper level low over the NE Caribbean. No significant convection
is depicted over water at this time near this wave.
A tropical wave is in the W Caribbean with axis along 82W-83W, S
of 16N, extending across western Panama, moving west near 10 kt.
Moderate convection associated with this wave is inland and along
the coasts of Central America from western Panama to central
Nicaragua.
...MONSOON TROUGH/ITCZ...
The monsoon trough exits Africa along the coast of Mauritania near
17N16W and extends to the remnant low of Gonzalo near 19.5N23W
then southwestward to 09.5N33W to 09N38W. The ITCZ extends from
09N40W to 12N55W to 11N60W. Scattered moderate convection is
noted within 180 nm SE of the monsoon trough between 20W and 36W.
Scattered moderate isolated strong convection is noted from 08N
to 12.5N between 48W and 61W.
...GULF OF AMERICA...
A dissipating frontal boundary extends across the basin from the
western tip of Cuba to the NE Mexican coast along 24.5N. Widely
scattered clusters of moderate convection are within 75 nm S of
this boundary. Isolated weak showers are elsewhere to the N across
northwest and north-central portions. The upper level trough
across the basin in recent days has weakened considerable and
drifted SE and now extends from central Florida southwestward
across SE portions and the Bay of Campeche. Scattered moderate
convection is also along and ahead a surface trough across the
western Yucatan Peninsula and moving into the immediate coastal
waters. Surface observations indicate that a weak 1014 mb high
center has shifted southward into the NE Gulf offshore of the
Florida-Alabama border. Light to gentle anticyclonic winds prevail
across the basin with a few small zones of moderate E winds
occurring N of the front offshore of Louisiana and across the
upper Mexican offshore waters. Seas are 3 ft in these areas and
less than 3 ft elsewhere.
For the forecast, light to gentle winds, and slight to moderate
seas, will prevail through the weekend. Winds and seas will
gradually increase to gentle to moderate speeds Mon, and to
moderate to fresh speeds Tue night through Thu night, as high
pressure shifts into the eastern Gulf and a frontal system moves
into the Central Plains. Slight seas basin-wide will build to
moderate Wed night through Thu following the increase in winds.
...CARIBBEAN SEA...
A weaker than normal pressure gradient across the western Atlantic
and Caribbean basin is translating to gentle to moderate trades
over most of the basin. Moderate to locally fresh winds are
occurring across the waters S of 13.5N between NW Venezuela and NE
Colombia, and in the Gulf of Honduras, where seas are 3 to 5 ft.
Moderate winds follow the tropical wave and extend into the
Windward Islands. Seas are 2 to 4 f there. Elsewhere light to
gentle winds prevail with seas 3 ft or less.
For the forecast, a weak pressure gradient will support gentle to
moderate trades across the Caribbean through Mon night. High
pressure will build E of the Bahamas on Tue, which will result in
trades reaching moderate to fresh speeds basin-wide. Seas will be
slight to moderate through the period.
...ATLANTIC OCEAN...
See Special Features section above for information on Post-
Tropical Cyclone Gonzalo.
Large N to NE swell generated by Low pressure off the East Coast
of the U.S. and associated frontal system continues to dominate
the waters N of 24N and W of 70W, becoming NW swell N of 25N
between 64W and 70W. This swell has peaked in the past 24 hours
and is beginning to subside, with maximum seas now 10-11 ft
between 29N and 31N, except higher in the Gulfstream. This swell
will continue to gradually subside through Mon, while gradually
becoming more NW to N, and propagating to the waters near 60W by
late Mon.
Tropical Depression Fay is centered near 29.6N 43.9W at 27/0300,
moving S at 2 kt. Estimated minimum central pressure is 1010 mb.
Maximum sustained wind speed is 30 kt with gusts to 40 kt. Peak
seas to 10 ft are within 60 nm N of center, while seas of 6 to 10
ft are found across the area N of 28N between 40W and 47W.
Numerous moderate to strong convection has recently erupted within
120 nm across the SW semicircle.
A vigorous upper-level trough along the eastern seaboard of the
U.S. supports the deep low pressure off the NE Atlantic coast,
and supports a cold front across the western Atlantic waters
extending through 31N68W through the central Bahamas and into
western Cuba. Scattered to locally numerous moderate isolated
strong convection is ongoing E of this front, from NE Cuba and NW
Hispaniola through the Turks and Caicos, to the area between the
front and 30N72W. Moderate to locally fresh SW to S winds
generally prevail E of the front from 21N north-northeastward to
beyond 31N and W of 62W. Seas are 4 to 9 ft in northerly swell
described above, highest N of 27N. To the east, a surface trough
supported by a mid-level low is inducing numerous moderate
convection from 26N to 30N between 55W and 60W. Moderate to
locally fresh S winds and seas 5 to 7 ft are present in the
vicinity of this trough. To the SE, a belt of gentle to moderate
trades prevails from 10N to 21N W of 34W to the Lesser Antilles,
where seas are 5 to 6 ft. Farther E, moderate to fresh NE winds
prevail N of the monsoon trough to 24N between 24W and 33W, where
seas are 7 to 10 ft in NE swell from Gonzalo. Otherwise mainly
gentle winds prevail.
For the forecast west of 55W, the aforementioned cold front will
will reach from near Bermuda to central Cuba tonight before
starting to weaken. Scattered showers and isolated thunderstorms
are expected along and ahead of the front. Moderate to fresh SW
winds are expected E of the front through the remainder of the
weekend before diminishing Mon. Large northerly swell behind the
front will gradually subside through Mon.

Issued at 900 AM GMT Sun Sep 27 2026475 WTNT41 KNHC 270850 TCDAT1 Tropical Depression Fay Discussion Number 29 NWS National Hurricane Center Miami FL AL062026 900 AM GMT Sun Sep 27 2026 Fay's convection has redeveloped once again. Since the last advisory, an area of deep convection located just south of the storm's low-level center has grown in size, with cloud-top temperatures nearing -80°C at times. The latest subjective Dvorak intensity estimate from TAFB rated Fay at 1.5/25 kt, while objective analysis from UW-CIMSS estimates the storm's strength between 29-36 kt. Given Fay's pulsating cycles of convection, the initial intensity was held steady at 30 kt, with the caveat that brief periods of slightly stronger max winds are entirely possible. Initial motion remains slow at 170/3 kt. However, Fay is expected to gain forward speed soon as it escapes the influence of the Atlantic subtropical high and is picked up by the prevailing easterlies early next week. This will cause a turn to the southwest and then west. The latest track forecast is largely unchanged from the previous advisory, reflecting only a slight rightward shift to blend better with HCCA guidance. As long as Fay remains in an environment characterized by warm SSTs, its cycles of pulsating convection are expected to continue. It was anticipated that strong vertical wind shear would work to break apart Fay's circulation, but the storm has proven resilient. Global forecast models still suggest that convection will completely dissipate by the middle of next week at the latest, before Fay opens up into a trough shortly thereafter. Little was changed in the latest intensity forecast. Fay is expected to waver right around tropical depression or even weak tropical storm strength as convection pulsates, before eventually dissipating for good.

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
will drift SE and dissipate through late Tue. Its remnants will
drift N along 23N-24N. The pressure gradient between high
pressure off of Hatteras and the frontal boundary will support
an area of fresh to strong easterly winds N of 23N and W of 68W
with seas to 11 ft E of the Bahamas late Tue through Fri.

000<br />ABNT30 KNHC 011304<br />TWSAT <br /><br />Monthly Tropical Weather Summary<br />NWS National Hurricane Center Miami FL<br />900 AM EDT Thu May 1 2025<br /><br />This is the last National Hurricane Center (NHC) Tropical Weather <br />Summary (TWS) text product that will be issued for the Atlantic <br />basin. The tropical cyclone statistics from the TWS will be found <br />on hurricanes.gov beginning with the 2025 hurricane season. This <br />change will allow for more frequent updates to the statistics and <br />the addition of graphics and links to supporting information that <br />this text only format cannot support. An account of tropical <br />cyclone names, classification (i.e., tropical depression, tropical <br />storm, or hurricane), and maximum sustained wind speed will be found <br />on hurricanes.gov at this url beginning around July 1: <br /><br />https://www.nhc.noaa.gov/data/tcr/index.php?basin=atl<br /><br />A sample webpage is provided here, with the "2023 Atlantic Summary <br />Table (PDF)" example linked below the Tropical Cyclone Reports <br />(TCRs):<br /><br />https://www.nhc.noaa.gov/data/tcr/index.php?season=2023&basin=atl <br /><br />This information will be updated no less frequently than monthly <br />during the hurricane season and will be updated after the season's <br />TCRs are completed to document the official record of the season's <br />tropical cyclone activity. Previously, the statistics and data in <br />the TWS were based on real-time operational assessments and were <br />not updated when the season's TCRs were complete. The new <br />web-based format allows the information to be updated once the <br />post-analysis for the season is complete. <br /><br />For more information, see Service Change Notice 25-22: Migration of <br />the Tropical Weather Summary Information from Text Product Format to <br />hurricanes.gov:<br /><br />https://www.weather.gov/media/notification/pdf_2025/scn25-<br />22_moving_info_from_tws_to_hurricanes.gov.pdf
