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...
Central Atlantic Gales and Significant Swell:
A strong cold front curves west-southwestward from east of Bermuda
across 31N62W to beyond 31N77W. It will bring W to NW near-gale to
gale-force winds across the central Atlantic, north of 29N between
56W and 62W tonight through early Thu morning. In addition, large
NW swell behind the cold front will cause 12 to 15 ft seas north
of 30N between 57W and 67W late tonight. Seas are expected to
build higher to between 12 and 20 ft and spread to 27N between
53W and 69W by early Thu morning. Then these seas will gradually
subside to between 12 and 17 ft but shift to north of 25N between
49W and 64W Thu evening.
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 Guinea coast near
Conakry, then curves southwestward to 04N19W. An ITCZ continues
from 04N19W through 03N35W to just north of Belem, Brazil at
0.5N48W. Scattered moderate to isolated strong convection is
noted near and north of the ITCZ from 00N to 06N between 43W and
the Brazil/French Guiana coast. Widely scattered moderate
convection is found south of the monsoon trough from 04N to 06N
west of 15W.
...GULF OF AMERICA...
A surface trough is triggering scattered showers and isolated
strong thunderstorms at the central Bay of Campeche. Otherwise, A
1027 mb high at the northeastern Gulf is dominating the rest of
the Gulf. Moderate to fresh ENE to E winds and seas of 4 to 7 ft
are present at the south-central and southeastern Gulf, including
the Straits of Florida. Gentle to moderate ENE to ESE winds and 3
to 5 ft seas are noted at the north-central Gulf. Light to gentle
winds with seas at 1 to 3 ft prevail for the rest of the Gulf.
For the forecast, the 1027 mb high will continue to support
moderate to fresh NE to E winds and moderate to rough seas across
the south-central and southeastern Gulf through tonight. Areas of
fog are possible across the northern Gulf into Thu. A ridge will
remain in control of the weather pattern across the Gulf region
the remainder of the week, with a high pressure center located
over the northeastern Gulf Thu through Sat. This system will
produce mainly a gentle to moderate wind flow with slight to
moderate seas. Looking ahead, the next cold front is expected to
enter the northwestern Gulf on Mon, followed by fresh to strong
northerly winds and rough seas, except gale conditions will be
possible in the far west-central Gulf, and in the northwest part
of the southwestern Gulf Mon night.
...CARIBBEAN SEA...
A robust trade-wind regime continues across much of the Caribbean
Sea. Convergent trades are creating scattered showers and isolated
thunderstorms at the Gulf of Honduras, and south of Haiti. Fresh
to strong NE winds and seas of 5 to 8 ft are evident at the
south-central basin, lee of Cuba, near the Windward Passage
and near Hispaniola. Gentle to moderate NE winds and 3 to 5 ft
seas are seen at the eastern basin. Moderate to fresh NE to E
winds and seas at 4 to 6 ft prevail elsewhere in the Caribbean
Sea.
For the forecast, strong high pressure across the western
Atlantic combined with the Colombian low will continue to support
fresh to strong winds in the lee of Cuba, the Windward Passage,
and the central Caribbean through Thu night, except through Mon
off Colombia. Long-period northerly swell moving into the
northeastern passages will gradually subside Thu. This will be
followed by additional northerly swell arriving into northeastern
passages late Fri into Sat before subsiding Sun.
...ATLANTIC OCEAN...
See Special Features at the beginning about Gales and Significant
Swell.
A strong cold front curves west-southwestward from east of Bermuda
across 31N62W to beyond 31N77W. Patchy showers and isolated
thunderstorms are occurring near and up to 50 nm north of the
front. Convergent SE to SW winds farther east are causing
scattered to numerous showers and isolated strong thunderstorms
north of 27N between 56W and 63W. At the central Atlantic, a
weakening stationary front reaches southwestward from the north-
central Atlantic across 31N37W to 23N57W. Scattered moderate
convection is occurring up to 150 nm along either side of this
boundary. Refer to the Monsoon Trough/ITCZ section for additional
convection in the Atlantic Basin.
Outside the area mentioned in the Special Features section,
Moderate to fresh W to NW winds and seas of 6 to 10 ft dominate
north of 27N between 52W and 72W. Gentle to moderate N to NE
winds and 4 to 6 ft seas are present north of 20N and west of 72W.
From 20N to 27N between 52W and 72W, gentle to moderate N to NE
winds and seas at 7 to 9 ft in large northerly swell exist.
Farther east, north of 20N between 35W and 52W, gentle to moderate
SE to S winds with 6 to 10 ft seas in large NW swell are noted.
For the tropical Atlantic from 06N to 20N between 35W and the
Lesser Antilles, gentle to moderate NE to ESE winds and seas of 6
to 8 ft are evident. For the remainder of the Atlantic Basin west
of 35W, light to gentle winds and 4 to 6 ft seas in mixed moderate
swells prevail.
For the forecast west of 55W, the stationary front will gradually
dissipate tonight. The aforementioned strong cold front is
anticipated to move across the Atlantic waters east of the
Bahamas through early Thu while weakening. Large swell continues
to impact the region east of the Bahamas. Strong winds and a new
set of large reinforcing swell will follow this front, mainly over
the waters east of 70W through Thu. Another cold front will move
over the waters between northeastern Florida and Bermuda Fri
before moving east of the area Sat. It will be followed by
additional reinforcing swell east of 70W. Looking ahead, yet
another front will move off northeastern Florida coast Sat, and
move east of the region through Mon.

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
