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
0830 UTC.
...MONSOON TROUGH/ITCZ...
The monsoon trough extends from 13N17W to 02N30W. The ITCZ
continues from 02N30W to 02S42W. Scattered moderate to isolated
strong convection is along and south of the boundaries mainly W
of 20W.
GULF OF AMERICA...
A cold front extends across the Florida Straits westward to near
24N85W, then dissipating front to 22N93W. Fresh to strong winds,
and seas of 5-8 ft, prevail N of the front and E of 90W. Moderate
winds, and seas of 5-7 ft, are found W of 90W.
For the forecast, fresh to locally strong NE winds and moderate
to rough seas will prevail N of the front today. The western
portion of this boundary will gradually dissipate over the central
and western Gulf today, while the eastern portion will move
across Cuba and the Yucatan Channel before stalling along about
21N Wed and dissipating early Thu. Gentle to moderate
southeasterly winds will return to the Gulf on Thu.
CARIBBEAN SEA...
A weak pressure gradient is supporting moderate to fresh winds off
the coast of Colombia. Gentle to moderate winds prevail elsewhere.
Seas are in the 4-6 ft range E of 75W, and 3-4 ft W of 75W.
For the forecast, weak Atlantic high pressure will continue N of
the basin and support a weaker than usual pressure gradient over
the Caribbean basin throughout the week. Fresh to strong NE winds
will develop tonight and Wed night across the Windward Passage and
in the lee of Cuba, associated with a late-season cold front
moving slowly across Cuba. The front is expected to dissipate
across eastern Cuba early Thu. Tranquil marine conditions are
expected across the entire basin Fri and Sat.
ATLANTIC OCEAN...
A cold front extends from 31N65W southwestward across the central
Bahamas and across the Florida Straits. Fresh to near- gale winds,
and seas of 7-11 ft prevail W of the front. The rest of the
Atlantic discussion waters are dominated by high pressure. Winds
are generally moderate to locally fresh across these waters.
Northerly swell generated by a gale force low well north of the
area is bringing seas of 8-11 ft to the waters N of 27N between
20W and 45W. Elsewhere, seas are in the 4-7 ft range.
For the forecast west of 55W, fresh to strong N to NE winds and
rough seas will follow the front as it continues moving
southeastward, reaching from 31N60W to the NW coast of Cuba by
this afternoon, and then begin to stall and weaken from 31N55W to
25N60W to eastern Cuba along 21N Wed morning. Winds will diminish
Wed as the front stalls and dissipates along 21N by early Thu.
Weak high pressure will settle in between northeast Florida and
Bermuda Thu through Sat, in the wake of the front. Large N to NE
swell will linger near the weakening front Tue night through Thu
morning, including waters near the Windward Passage.

Marine Weather Discussion
NWS National Hurricane Center Miami FL
1122 AM EDT Mon May 17 2021
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.

.WARNINGS...Any changes impacting coastal NWS offices will be
coordinated through AWIPS II Collaboration Chat, or by
telephone:
.GULF OF MEXICO...
None.
.CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN

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
