0615 UTC Sat Dec 13 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.
...SPECIAL FEATURES...
East Atlantic Gale Warnings:
MeteoFrance has issued Gale Warnings for their MADEIRA and
CANARIAS Marine Zones. For Madeira, the warning is valid through
13/21Z, and for Canarias, the warning is valid through 14/00Z.
Please visit website:
wwmiws.wmo.int/index.php/metareas/display/2 for more information.
...MONSOON TROUGH/ITCZ...
The monsoon trough enters the Atlantic near 07N12W and extends to
05N17.5W. The ITCZ continues from 05N17.5W to 01N30W to 00N48W.
Scattered moderate convection is occurring from 02N to 11N east
of 29W.
...GULF OF AMERICA...
A surface trough has been analyzed over the central Bay of
Campeche to 24N94W, and locally fresh E to NE winds are noted over
the eastern Bay through the Campeche Bank. Elsewhere, a 1021 mb
high centered over northern Florida extends ridging through the
Gulf, supporting moderate or weaker winds over much of the basin.
Locally fresh E to NE winds, observed on recent scatterometer
data, are noted through the Florida Straits as a moderate pressure
gradient prevails between the ridge and a surface trough over the
northwestern Caribbean. Seas of 1 to 2 ft are observed over the
northern and northeastern basin via recent buoy data, with 2 to 4
ft seas noted in the southern and western Gulf.
For the forecast, weak high pressure located over north Florida
and the adjacent Atlantic will slide northeastward and into the NW
Atlantic through Sat to produce moderate to occasionally fresh E
to SE winds across the S and W Gulf. Otherwise, moderate or weaker
winds and slight seas are expected over the remainder of the
basin through Sat. The next cold front is expected to enter the
northern Gulf on Sun morning, bringing strong N to NE winds and
building seas behind the front. The front is expected to reach the
south-central Gulf along 24N/25N by Mon morning, and move south
of the basin Mon night.
...CARIBBEAN SEA...
Widespread fresh trade winds are noted over much of the
Caribbean, as a tight pressure gradient prevails between a 1007 mb
low over the south-central Caribbean, a surface trough over the
northwestern basin and ridging to the north. Recent scatterometer
satellite data show ongoing strong winds in the south-central
basin, with locally near-gale force winds noted in the Gulf of
Venezuela. Seas of 8 to 10 ft are occurring in the central and
west-central basin to the west of the strongest winds, with 6 to 8
ft seas noted in the eastern Caribbean, and 4 to 6 ft in the
northwestern basin. Elsewhere, fresh to locally strong trade winds
and 8 to 11 ft seas, as noted via recent altimeter data, prevail
over the Atlantic waters and through the passages.
For the forecast, fresh to strong winds, and moderate to rough
seas are expected over the central Caribbean through Sun morning
due to the pressure gradient between the Colombian low and a
modest western Atlantic ridge. Winds will pulse to near gale-force
at night offshore of northern Colombia. Elsewhere, fresh to
locally strong trade winds and rough seas in large E swell will
prevail over the Atlantic waters, through the Atlantic passages
and into the eastern part of the basin through Mon. A cold front
will enter the northwestern Caribbean early Mon, accompanied by
increasing winds and building seas behind the front. This front is
expected to reach from central Cuba to N Belize Tue evening, then
begin to stall and weaken.
...ATLANTIC OCEAN...
Please see the Special Features section above for more information
about the Gale warning in effect over the Eastern Atlantic.
A cold front extends from 31N56W to 24N70W, where it transitions
to a stationary front that continues through the central Bahamas
and central Cuba. Scattered moderate convection is noted near and
ahead of the cold front, north of 26N between 53W and 62W.
Moderate to locally fresh S to SW winds are noted via
scatterometer data ahead of the front, while gentle to moderate
winds prevail to the north. A NW swell associated with this cold
front is supporting 8 to 10 ft seas north of 28N between 52W and
70W. Farther west, a 1021 mb high centered near 30N77W extends
ridging over the northwest tropical Atlantic. The pressure
gradient between this high and the aforementioned cold and
stationary fronts is supporting moderate to fresh NE winds north
of the Lesser Antilles and through the Bahamas. Elsewhere, a cold
front extends from 31N10.5W through northwestern Africa to 22N20W
to 25N40W, and strong to gale force winds and 10 to 20 ft seas
prevail north of the front. Widespread fresh to locally strong
trade winds and rough seas prevail south of 25N.
For the forecast, large NW swell is expected north of 28N between
70W and the aforementioned cold and stationary fronts through Sat
morning as the north portion of front drifts eastward. The front
is forecast to become stationary Sat, then lift northward while
dissipating. The next strong cold front is slated to move off the
coast of the southeastern United States on Sun, with strong to
near gale-force winds and quickly building seas expected behind
the front. The front is forecast to reach from just E of Bermuda
to the central Bahamas by Mon morning, and from 29N55W to the SE
Bahamas and central Cuba Tue morning.

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. 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
