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
0900 UTC.
...SPECIAL FEATURES...
Gulf of America Gale Warning: A strong cold front will enter the
NW Gulf waters early this morning. Gale force winds and rough
seas are expected in the wake of the front off the coast of Texas
and Louisiana early this morning, and offshore of Tampico and
Veracruz by this afternoon and night. Prolonged gale force winds
and significant very rough seas will persist over the western Bay
of Campeche through late Tue night. Seas will peak around 20 ft
off Veracruz Tue. Conditions will improve from north to south by
midweek.
Central Atlantic Gale and Significant Swell: A couple of cold
fronts are moving through the north central waters, extending from
a storm force low centered near 42N49W. The first cold front
extends from 31N44.5W to 22N61W to 24N71W. The second cold front
enters the waters near 31N47W to 25N61W to 26N70W. Near-gale to
gale force winds are on either side of the front N of 28N between
41W and 54W. Elsewhere, fresh to strong winds are over the waters
N of 23N between 38W and 60W. Winds W of the front will diminish
below gale force this morning, with gale force winds continuing N
of 28N within 60 nm east of the front through this afternoon.
Large N swell generated from the storm system is producing very
rough seas greater than 12 ft over the forecast waters N of 24N
between 40W and 63W. These very rough seas will shift eastward
while gradually subsiding from south to north through the week.
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
information.
...MONSOON TROUGH/ITCZ...
The monsoon trough reaches the Atlantic through the coast of
Guinea near 10N14W and continues to 06N19W. The ITCZ continues
from 06N19W to 00N48W. Scattered moderate and isolated strong
convection is noted from 01N to 05N between 11W and 25W.
...GULF OF AMERICA...
Please read the Special Features section above on a Gale Warning.
A surface trough is noted over the SW Gulf, with moderate winds in
the vicinity of the trough. The remainder of the Gulf if under the
influence of high pressure, anchored by a 1019 mb high centered
over the eastern Gulf. Light to gentle winds are in the vicinity
of the high center, with gentle to locally moderate winds
elsewhere. Seas are in the 1-2 ft range in the eastern Gulf, and
2-4 ft elsewhere.
For the forecast, a cold front will move into the northern Gulf
by early this morning. The front will rapidly shift across the
Gulf waters, moving SE of the area Tue. Gale force winds and rough
seas are expected in the wake of the front off the coast of Texas
and Louisiana early this morning, and offshore of Tampico and
Veracruz by this afternoon and night. Prolonged gale force winds
and significant very rough seas will persist over the western Bay
of Campeche through late Tue night. Widespread strong to near-gale
force winds and rough seas are expected elsewhere behind the
front. Winds and seas will diminish from north to south through
midweek. High pressure will build over the basin following the
front with moderate or weaker winds and moderate seas through late
this week.
...CARIBBEAN SEA...
The pressure gradient between high pressure N of the area and the
Colombian low is supporting fresh to strong winds, and seas of 6-9
ft, over the south central Caribbean. Moderate to fresh winds,
and seas of 5-7 ft, prevail over the north central Caribbean.
Moderate winds and moderate seas are noted elsewhere.
For the forecast, fresh to occasionally strong trade winds and
rough seas are expected over the central Caribbean through the
middle of the week as a moderate pressure gradient prevails
between the Colombian low and high pressure to the north. Winds
may reach near-gale force offshore of northern Colombia tonight.
Moderate to occasionally fresh trade winds and moderate seas are
expected over the rest of the basin through midweek. Elsewhere, a
long period N to NW swell will bring rough seas over the Atlantic
waters this week. A cold front will move into the northwestern
basin late Tue into Wed, and weaken as it moves southeastward and
dissipates on Thu.
...ATLANTIC OCEAN...
See the Special Features section above for details on a gale
warning and a significant swell event in the central Atlantic.
Aside from the cold fronts with gale warnings, and the significant
swell with very rough seas 12 ft or greater, rough seas greater
than 8 ft cover the waters N of a line from 28N70W to 15N54W to
30N22W. Moderate to locally fresh winds, and seas of 6-8 ft are
over the deep tropics S of 12N between 35W and 60W. Elsewhere,
winds are moderate or weaker with moderate seas.
For the forecast west of 55W, fresh to strong W to NW winds and
very rough seas will continue over the central tropical Atlantic,
north of 22N and east of 65W, through this morning as a series of
cold fronts extending from a storm system north of the area move
over the region. Widespread rough seas associated with this storm
system will prevail east of 70W will subside from west to east
early this week. Farther west, fresh to locally strong W to SW
winds will develop offshore of Florida on today ahead of another
cold front moving through the southern U.S. This front will move
offshore by late today, with fresh to strong W to NW winds and
rough seas in the wake of the front. These winds and seas will
expand eastward toward the central Atlantic through midweek as the
front moves eastward. Another cold front is expected to enter the
northwest tropical Atlantic late this week, with increasing winds
and building seas near and behind the front.

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.
