Tropical Weather Discussion
NWS National Hurricane Center Miami FL
0615 UTC Sat Dec 27 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
0530 UTC.
...SPECIAL FEATURES...
Western and Central Atlantic Significant Swell:
A cold front extends southwestward from the north-central
Atlantic across 31N50W to 28N70W. A new set of large NW swell
behind the front is producing 12 to 17 ft seas north of 28N
between 50W and 63W. Expect this area of rough to very rough seas
to progress eastward through Sat night. Afterward, another set of
NW swell will arrive and sustain very rough seas through early
next week.
Please read the latest High Seas and Offshore Waters Forecasts
issued by the National Hurricane Center at website:
https://www.nhc.noaa.gov/text/MIAHSFAT2.shtml and
https://www.nhc.noaa.gov/marine/offshores.php for more
information.
...MONSOON TROUGH/ITCZ...
A monsoon trough enters the Atlantic along the Sierra Leone coast near
Freetown, then runs southwestward to 06N18W. An ITCZ continues
west-southwestward from 06N18W to 03N30W to 01N42W. Scattered
moderate to isolated strong convection is observed up to 80 nm
along either side of the ITCZ. Widely scattered showers are seen
south of the monsoon trough from 04N to 06N between 10W and 16W.
...GULF OF AMERICA...
A surface trough is triggering widely scattered showers at the
western Bay of Campeche. Otherwise, a 1019 mb high over the
northeastern Gulf is dominating much of the Gulf with light to
gentle winds and 1 to 2 ft seas north of 23N. South of 23N, gentle
to moderate NE to E winds and seas of 2 to 3 ft prevail,
including the Florida Straits and Bay of Campeche.
For the forecast, a weak pressure gradient will support gentle to
moderate E to SE winds and slight to moderate seas across the
Gulf through late Sun. The next cold front is expected to enter
the northwestern Gulf early Mon, followed by fresh to strong
northerly winds and rough seas, except gale conditions will be
possible in the far west-central and southwestern Gulf by Mon
night.
...CARIBBEAN SEA...
Convergent trade winds continue to generate scattered showers and
isolated thunderstorms at the western Gulf of Honduras, and off
the Nicaragua coast. A broad subtropical ridge in the western
Atlantic sustains a trade-wind regime across most of the Caribbean
Sea. Fresh to strong NE winds and seas of 7 to 10 ft are present
at the south-central basin. Moderate to fresh NE to E winds and 4
to 6 ft seas are noted at the north-central and part of the
southwestern basin. Gentle to moderate ENE to E winds and seas at
3 to 5 ft prevail elsewhere in the Caribbean Sea.
For the forecast, the pressure gradient between the subtropical
ridge and the Colombian low will support fresh to strong winds off
Colombia through mid week, with moderate to fresh trade winds
elsewhere.
...ATLANTIC OCEAN...
Please read the Special Features section at the beginning about
the ongoing significant swell.
A cold front extends southwestward from the north-central
Atlantic across 31N50W to 28N70W, then continues northwestward as
warm front to beyond 31N74W. Scattered moderate convection is
evident near and up to 80 nm southeast of the cold front east of
54W. Patchy showers are seen up to 50 nm south of the rest of the
cold front. At the central Atlantic, convergent southerly winds
near a surface trough is triggering scattered moderate convection
north of 22N between 37W and 41W. Refer to the Monsoon Trough/ITCZ
section for additional convection in the Atlantic Basin.
Outside of the large swell area described in the Special Features
section, moderate to fresh with locally strong SW to NW winds and
8 to 11 ft seas are noted north of 25N between 35W and 65W. West
of 65W and north of 25N, gentle to moderate with locally fresh SW
to W winds and 4 to 8 ft seas exist. To the south from 13N to 25N
between 35W and the Bahamas/Lesser Antilles, a broad subtropical
ridge is supporting light to gentle winds and 6 to 10 ft seas in
large NW swell. For the tropical Atlantic from 00Z to 13N and west
of 35W, moderate to fresh NE to E winds with seas at 6 to 8 ft in
mixed moderate swell prevail.
For the forecast west of 55W, the cold front will move east of 35W
through early Sun. Fresh to strong winds near the front will
diminish through tonight. Large N swell following the front will
mix with earlier large swell still covering the area east of 65W.
Another cold front will move into the waters between northeast
Florida and Bermuda by late Sat, and move east of 35W by early
Mon, leaving a trailing stationary front to dissipate along 21N.
Strong winds and additional large N swell follow this front across
waters east of 70W into early next week. A third cold front will
move off the northeast Florida coast Mon night, and will reach
from Bermuda to Jupiter Inlet, Florida by late Tue, and from
31N60W to central Cuba by late Wed.

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. 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
