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 1600 UTC surface analysis and satellite imagery through
1600 UTC.
...MONSOON TROUGH/ITCZ...
A monsoon trough enters the Atlantic near the coastal border of
southern Senegal and Guinea Bissau, then curves southwestward
through 06N20W to 03N24W. An ITCZ continues west-southwestward
from 03N24W through 00N35W to near Sao Luis, Brazil. Numerous
moderate to scattered strong convection is flaring up near and
south of the monsoon trough from 07S to 05N between 10W and
20W. Scattered moderate convection is found near and up to 100 nm
along either side of the ITCZ.
...GULF OF AMERICA...
The southeastern end of a cold front curves southwestward across
the Florida Straits to just northwest of the Yucatan Channel.
Scattered showers are observed near and up to 60 nm north of the
front. Two modest surface troughs are triggering additional
showers at the central Gulf. Fresh to strong ENE winds and seas of
6 to 8 ft dominate the Florida Straits and southeastern Gulf.
Moderate to fresh E to ESE winds with 3 to 6 ft seas are noted at
the northeastern Gulf. Gentle to moderate E to SE winds and seas
at 2 to 4 ft prevail for the rest of the Gulf.
For the forecast, the cold front is going to move over Cuba this
afternoon. In response, fresh to locally strong winds and rough
seas will gradually diminish in the southeastern Gulf in the wake
of the front into tonight. Gentle to moderate southeasterly winds
will return to the Gulf on Thu.
...CARIBBEAN SEA...
The southwestern end of a surface trough is producing patchy
showers near Hispaniola. Otherwise, a modest trade-wind regime is
persisting across much of the basin. Moderate ENE winds and seas
of 3 to 6 ft are present at the lee of Cuba and northwest of
Colombia. Mainly gentle NE to E winds with 2 to 4 ft seas prevail
elsewhere in the Caribbean Sea.
For the forecast, weak Atlantic high pressure will persist north
of the basin and support a weaker than usual pressure gradient
over the Caribbean basin throughout the week. Fresh to locally
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 across Cuba. The front is expected to
dissipate near the Windward Passage Wed night. Tranquil marine
conditions are expected across the entire basin Fri and Sat.
...ATLANTIC OCEAN...
A cold front curves southwestward from northeast of Bermuda across
31N62W to beyond the central Bahamas. Scattered moderate
convection is seen near and up to 200 nm southeast of this
boundary. To the south, convergent trade winds are coupling with
divergent winds aloft to trigger numerous heavy showers and
scattered thunderstorms near the coast of French Guiana, and State
of Amapa in Brazil.
Fresh to strong N to NE winds and seas of 9 to 11 ft are evident
behind the aforementioned front, except gentle to moderate NE to
ENE winds and 5 to 8 ft seas off northeast Florida to 75W. Fresh
with locally strong S to SW winds and seas at 5 to 8 ft are found
ahead of the front, north of 28N between 56W and the front. To the
east, gentle to moderate ENE to SSE winds and seas of 4 to 7 ft
dominate north of 20N between 35W and 55W. For the remainder of
the Atlantic Basin west of 35W, gentle to moderate NE to E winds
and 4 to 6 ft seas in mixed moderate swells.
For the forecast west of 55W, fresh to strong NE winds and rough
seas will follow the front as it progresses eastward through Thu,
although conditions in the wake of the front will gradually
improve as the front weakens late this week. High pressure will
settle in between northeast Florida and Bermuda for the end of the
week, bringing tranquil conditions to area waters into the
weekend.

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
