Tropical Weather Discussion
NWS National Hurricane Center Miami FL
0615 UTC Wed Dec 10 2025
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
0500 UTC.
...MONSOON TROUGH/ITCZ...
A monsoon trough enters the Atlantic near the coastal border of
Sierra Leone and Liberia, then runs southwestward to 05N16W. An
ITCZ curves westward from 05N16W to 01N34W to 03N44W. Scattered
moderate to isolated strong convection is noted near and up to
200 nm north of the ITCZ between 20W and 40W. Widely scattered
moderate convection is seen the ITCZ and monsoon trough from 01N
to 08N between 10W and 20W.
The eastern end of the East Pacific monsoon trough is causing
isolated thunderstorms across the Caribbean waters near Costa Rica
and Panama.
...GULF OF AMERICA...
A surface trough is generating scattered showers at the south-
central Gulf and Florida Straits. Otherwise, a broad surface ridge
extending southwestward from the Florida Panhandle is dominating
much of the Gulf. Moderate to fresh NE to ENE winds and seas of 6
to 9 ft are present across the south-central and southeastern
Gulf, including the Florida Straits. Gentle to moderate NE to SSE
winds with 3 to 6 ft seas prevail for the rest of the Gulf.
For the forecast, moderate to fresh winds and rough seas will
continue in the south-central and southeastern Gulf tonight
behind a stalled front over the Yucatan Peninsula/Channel and
western Cuba. Elsewhere, moderate to locally fresh W to NW winds
and moderate seas will develop in the northeastern basin by Wed
ahead of a cold front moving through the southern United States.
This front is slated to enter the northern Gulf by early Thu,
with winds turning to the north in the wake of the front.
Otherwise, moderate or weaker winds and slight seas are expected
over the remainder of the Gulf into this weekend as weak high
pressure prevails over the basin.
...CARIBBEAN SEA...
A stationary front stretches southwestward from the Great Bahama
Bank across western Cuba and the Yucatan Channel into the Yucatan
Peninsula. Patchy showers and isolated thunderstorms are found up
to 50 nm along either side of the front. A surface trough is
creating widely scattered moderate convection near and west of
Jamaica. Refer to the Monsoon Trough/ITCZ section at the
beginning for more information. Fresh to locally strong ENE to E
winds with 5 to 7 ft seas dominate the south-central basin.
Moderate to fresh ENE to E winds and 4 to 6 ft seas are present at
the north-central and eastern basin, and part of the western
basin.
For the forecast, moderate to fresh NE winds and rough seas will
continue in the central and the southeastern basin tonight behind
a stalled front that extends from western Cuba to the Yucatan
Peninsula. Elsewhere, moderate to locally fresh W to N winds and
moderate seas will develop in the northeastern basin by Wed ahead
of a cold front moving through the southern United States. This
front is slated to enter the northern Gulf by early Thu, with
winds turning to the north in the wake of the front. Otherwise,
moderate or weaker winds and slight seas are expected over the
remainder of the Gulf into this weekend as weak high pressure
prevails over the basin.
...ATLANTIC OCEAN...
A cold front extends southwestward from the north-central Atlantic
across 31N58W to 26N70W, then continues as a stationary front to
beyond the central Bahama. Scattered moderate convection is
occurring near and up to 200 nm northwest of this boundary.
Convergent trade winds are triggering scattered moderate
convection from 06N to 10N between 27W and 39W. Refer to the
Monsoon Trough/ITCZ section for additional convection in the
Atlantic Basin.
A 1021 mb high near 27N36W is dominating the central and eastern
Atlantic from 21N to 27N between 35W and 60W with gentle to
moderate E to SE winds, and 6 to 9 ft in large northerly swell. To
the north, tight gradient between the high and a 998 mb low
pressure in the north-central Atlantic is inducing fresh to strong
SW winds and seas at 8 to 12 ft north of 27N between 35W and 55W.
Farther west from 20N to 31N, between 55W/60W and the Florida and
southern Georgia coast, gentle with locally moderate SE to W to
NW winds and 6 to 10 ft seas in large northerly swell exist. For
the tropical Atlantic from 07N to 20N/22N between 35W and the
Lesser Antilles, moderate to fresh ENE to E winds and seas of 6 to
9 ft are noted. For the remainder of the Atlantic Basin west of
35W, gentle to moderate ENE to ESE winds and 5 to 7 ft seas
prevail.
For the forecast, fresh to strong SW winds and rough seas that
precede the front, north of 28N and east of 60W will diminish
late tonight into Wed. NW swell associated with this front will
expand southeastward over the northwestern tropical Atlantic
through Wed, supporting rough seas north of 27N by late tonight,
and north of 25N by Wed afternoon. Seas reaching to around 12 ft
will be possible north of 30N and east of 69W into Wed afternoon.
Seas will slowly subside from west to east, west of 65W, into
early Thu. Looking ahead, fresh to strong SW winds along with
rough seas will develop offshore of northern Florida by Wed
evening ahead of a cold front that will be moving across the
southern United States. This cold front is expected to move
offshore the southeastern U.S. coast Wed night, with fresh to
strong NW winds and rough seas expected in the wake of the front.

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
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.

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.
