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 1200 UTC surface analysis and satellite imagery through
1600 UTC.
...SPECIAL FEATURES...
Caribbean Sea Gale Warning: The pressure gradient between the
Atlantic high pressure and the Colombian low will continue to
support fresh to near gale-force trades across the central and
eastern Caribbean through the early part of the week. Winds
offshore of Colombia will pulse to gale-force Tue night. Seas of
8 to 12 ft are expected with the strongest winds.
Please read the latest High Seas Forecast issued by the National
Hurricane Center at website:
https://www.nhc.noaa.gov/text/MIAHSFAT2.shtml for more details.
...MONSOON TROUGH/ITCZ...
The monsoon trough enters the Atlantic near 10N14W to 01N24W. The
ITCZ continues from that point to the coast of Brazil at
02S42W. Scattered showers are noted along the ITCZ.
...GULF OF AMERICA...
A surface ridge extends across the basin from the W-central
Atlantic. Gentle winds are found N of 25N along with slight seas,
with gentle to moderate E-SE winds and moderate seas prevailing
elsewhere.
For the forecast, the surface ridge will prevail through
midweek. The pressure gradient between the ridge and lower
pressures over Mexico will support mainly moderate to fresh E to
SE winds basin-wide, pulsing to fresh and strong near the northern
Yucatan and the western Gulf in the evenings, and slightly weaker
winds overall in the northeastern Gulf. Seas will be slight to
moderate through Wed. A cold front may impact the northwestern
Gulf beginning Wed night, before moving across the basin through
Fri night with winds increasing to fresh to strong speeds and seas
building to 9 ft behind it. A brief period of gale force winds
may be possible offshore of Veracruz early on Thu.
...CARIBBEAN SEA...
Please see Special Features section above regarding a developing
Gale Warning in the south-central Caribbean.
A strong pressure gradient between the Colombian low and high
pressure to the north is supporting fresh to strong trade winds
over the central and eastern Caribbean. Winds are moderate to
fresh across much of the remaining basin. Rough seas prevail in
the central Caribbean. Seas are moderate in the eastern and SW
Caribbean, except locally rough near Atlantic passages, while
slight to moderate seas prevail elsewhere.
For the forecast, the pressure gradient between a Bermuda High and a
Colombian low will support fresh to strong trades across the
eastern basin through Tue, and the central basin through Wed
night. Winds offshore of northwestern Colombia will pulse to
gale-force during the night-time hours Tue night. Fresh to
locally strong NE to E winds will pulse near the Windward
Passage through mid-week. Moderate to fresh winds will pulse in
the Gulf of Honduras and Lee of Cuba through Wed night. Large
easterly trade-wind swell from the tropical North Atlantic will
keep rough seas near the Lesser Antilles through Wed night.
Marine conditions will improve slightly by the end of the week
as the pressure gradient weakens due to a weak cold front
approaching the NW Caribbean.
...ATLANTIC OCEAN...
Surface ridging dominates the central and western tropical
Atlantic, supporting widespread moderate to fresh trade winds
south of 27N. Rough seas in E swell are noted in this region as
well as east of the Lesser Antilles. Elsewhere, the remnants of a
frontal boundary are analyzed as a surface trough, extending from
31N37W to 25N41W. Fresh to strong NE winds are occurring N of 27N
between the trough and 37W. Associated remnant rough seas are
found N of 28N between 27W and 47W. Scattered showers and
thunderstorms are possible N of 22N between 33W and 42W. Farther
east, fresh to strong NE winds and rough seas in NE swell prevail
off the coast of northwest Africa, supported by a strong pressure
gradient between a high to the north over the Azores and lower
pressures over northwest Africa. Elsewhere, gentle to moderate
winds and moderate seas prevail over the rest of the basin.
For the forecast west of 55W, moderate to fresh easterly winds
will prevail south of 27N through midweek, reaching strong north
of Hispaniola into the Windward passage at times. Rough seas will
prevail within these winds and east of the central and southeast
Bahamas through Tue. Moderate or weaker winds can be expected
elsewhere across the region. Southerly fresh to strong winds may
develop off northern Florida Wed night ahead of a potential cold
front. That front may move offshore Thu with fresh to strong winds
and building seas behind it, weakening and slowing from near
Bermuda to the northern Bahamas by late Thu night.

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
