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 0600 UTC surface analysis and satellite imagery through
1000 UTC.
...SPECIAL FEATURES...
Caribbean Gale Warning: The pressure gradient between 1030 mb
high pressure over the central Atlantic and the Colombian low is
supporting fresh to near gale-force NE to E winds offshore
Colombia. These two features will remain in place through the
middle of the week, before the high pressure weakens and shifts
eastward. Drainage flow at night will enhance winds off Colombia
to gale force at night through Thu morning. Rough seas are
forecast with these winds.
Please read the latest High Seas Forecast issued by the
National Hurricane Center at website:
https://nhc.noaa.gov/text/MIAHSFAT2.shtml for more details.
Significant Heavy Rainfall in the Gulf of Honduras and northern
Central America: Periods of significant heavy rainfall are
expected through today as abundant tropical moisture interacts
with a shearline extending from eastern Cuba to the Gulf of
Honduras. Periods of heavy rainfall will continue through early
today in the Gulf and northern Honduras, where totals in excess
of 12 inches will be likely.
Please consult products from your local meteorological services
for additional information.
...MONSOON TROUGH/ITCZ...
The monsoon trough enters the Atlantic through the coast of
Guinea near 09N13W and continues southwestward to 03N24W. The
ITCZ extends from 03N24W to 03S40W. Scattered moderate convection
is noted within 120 nm on both sides of the ITCZ between 17W-36W.
...GULF OF AMERICA...
A strong surface ridge over the eastern United States forces
fresh to strong easterly winds and moderate to rough seas east of
90E, including the Florida Straits. Moderate to fresh easterly
winds and moderate seas are found west of 90E to a line from
southern Texas to Coatzacoalcos, Mexico. Elsewhere, light to
gentle winds and moderate seas are prevalent.
For the forecast, the fresh to strong northerly winds and
moderate to rough seas will persist through today. The next cold
front is slated to enter the NW Gulf Fri night into Sat followed
by fresh to strong winds and building seas. Reinforcing high
pressure in the wake of the front, may bring gale conditions first
near Tampico, then near Veracruz on Mon.
...CARIBBEAN SEA...
Please read the Special Features section on Potential Heavy
Rainfall in the NW Caribbean through midweek, as well as a Gale
Warning offshore Colombia.
A shearline extends from eastern Cuba to northern Honduras. Fresh
to strong NE winds, and moderate to rough seas, prevail W of the
shearline and north of 17N. Outside of the south-central
Caribbean, fresh to strong easterly winds and moderate seas are
found off southern Hispaniola and NE Caribbean. Easterly swell is
reaching the Atlantic water passages of the NE Caribbean, allowing
for localized rough seas. Elsewhere, moderate to fresh easterly
winds and moderate seas are evident.
For the forecast, strong high pressure over the SE of the United
States will continue to promote fresh to strong NE winds and
moderate to rough seas across the NW Caribbean through today.
These winds are transporting abundant tropical moisture into
northern Honduras supporting periods of locally heavy rainfall. A
surface trough, and associated area of moisture, will move across
the Leeward Islands late today, and over Puerto Rico on Thu,
likely reaching Hispaniola on Fri. This is forecast to increase
the likelihood of scattered showers and isolated thunderstorms
over the islands and surrounding waters.
...ATLANTIC OCEAN...
A stationary front enters the discussion waters near 31N63W and
continues to eastern Cuba. To the W of this front, a weakening
stationary front extends from 31N70W to 29N81W. Scattered showers
are noted near these boundaries. The pressure gradient between a
strong ridge over the eastern United States and the fronts
supports fresh to strong NE winds and moderate to rough seas W of
68W. The remainder of the basin is dominated by an extensive
subtropical ridge SW of the Azores, forcing fresh to near gale-
force easterly winds and rough to very rough seas south of 27N
and east of 67W. Elsewhere, moderate or weaker winds and moderate
seas are prevalent. Divergence aloft east of the Lesser Antilles
sustains a large area of scattered showers and isolated
thunderstorms, especially from 14N to 20N and between 45W and 57W.
For the forecast west of 55W, the Atlantic high pressure will
continue to promote fresh to strong NE to E winds and rough seas
east of 67W through Thu. The stationary front in the W Atlantic will
lift N and gradually dissipate through Thu, while the weakening
front W of the aforementioned one will dissipate today. The
pressure gradient over the W Atlantic will continue to support
fresh to strong NE winds in the vicinity of the Bahamas and the
Straits of Florida through today.

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
