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...
Central Atlantic Large Swell:
A weakening stationary front extends southwestward from the north-
central Atlantic across 31N46W to 23N63W. A shear line curves
westward from 23N63W to 24N78W. Near-gale NE winds prevail in the
vicinity of the front. These winds will continue to weaken as the
front dissipates gradually today. Large, long-period northerly
swell is maintaining seas at 12 to 18 ft up to 450 nm northwest of
the boundary. This northerly swell will steadily decline over the
next couple of days, allowing seas to gradually subside, possibly
dropping below 12 ft on Wed evening.
Please refer to the latest NWS High Seas Forecast issued by the
National Hurricane Center, at the following website:
https://www.nhc.noaa.gov/text/MIAHSFAT2.shtm for more details.
...MONSOON TROUGH/ITCZ...
The monsoon trough enters the Atlantic near 12N16W to 02N28W. The
ITCZ continues from that point to 02S44W. Scattered moderate
convection is noted S of 05N between 22W-33W.
...GULF OF AMERICA...
A surface ridge extends southwestward from the Florida Big Bend
area to near Tampico, Mexico. Moderate to fresh E winds and seas
at 4 to 6 ft are present across the Florida Straits, north of the
Yucatan Peninsula and at the eastern Bay of Campeche. Gentle to
moderate E to SE winds with 2 to 4 ft seas prevail for the rest of
the Gulf.
For the forecast, the high pressure will prevail across the Gulf
waters. Moderate to fresh E to SE winds and moderate seas are
expected over the E Gulf through Sat night. Over the western half
of the Gulf, moderate to fresh SE winds are forecast, except for
strong E to SE winds off the northern Yucatan Peninsula at night.
...CARIBBEAN SEA...
A robust trade-wind regime continues across much of the Caribbean
Sea. Fresh to strong NE winds are seen at the south-central basin,
in the lee of Cuba and the Dominican Republic, and near the
Windward Passage. Seas range from 8 to 11 ft at the south-central
basin, up to 8 ft near the Windward Passage, and 4 to 6 ft in the
lee of Cuba and the Dominican Republic. Mainly moderate NE to E
winds and seas of 3 to 6 ft prevail elsewhere in the Caribbean
Sea.
For the forecast, the pressure gradient between high pressure N of the
area and the Colombian low will support fresh to strong winds
and rough seas offshore Colombia through the forecast period,
pulsing to near gale at night through midweek. This pattern will
also support fresh to strong NE winds in the lee side of Cuba, the
Windward Passage, and south of Hispaniola through Thu night.
...ATLANTIC OCEAN...
Refer to the Special Features section for more information about
the large swell.
A stationary front extends southwestward from the north-central
Atlantic across 31N46W to 23N63W. A shear line curves westward
from 23N63W to over the central Bahamas. Scattered showers are
found near and up to 220 nm northwest of the front. A pre-
frontal trough is triggering similar conditions north of 25N
between 45W and 49W.
Outside of the very rough seas mentioned in the Special Features
section, fresh to strong NE winds and 8 to 11 ft seas are evident
behind the frontal boundary and shear line, except moderate to
fresh E to SE winds with 6 to 8 ft north of 25N between 78W and
the Florida/southern Georgia coast. Farther southeast, gentle to
moderate NE to E winds and seas at 7 to 11 ft in large N swell
exist from 18N to the stationary front between 57W and the
southeast Bahamas. For the remainder of the Atlantic west of 35W,
gentle to moderate NE to E winds and 4 to 7 ft seas prevail.
For the forecast west of 55W, the aforementioned stationary front
will dissipate on Tue. Strong high pressure building in the wake
of the front should keep fresh to strong NE to E winds, and rough
to very rough seas across most of the western Atlantic for the
second half of the week.

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
