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
0345 UTC.
...TROPICAL WAVES...
The axis of a far eastern Atlantic tropical wave is near 35W from
01N to 20N, with a 1012 mb low where the tropical wave intersects
the monsoon trough. This system is moving westward at around 10
to 15 kt. Scattered moderate to isolated strong convection is
noted from 04N to 16N between 30W and 40W. Although dry
and stable air is expected to limit development during the next day
or so, gradual development is anticipated thereafter, and a
tropical depression is likely to form during the middle to latter
part of this week as the system moves west-northwestward at 10 to
15 mph over the central tropical Atlantic. There is a low chance
of development within the next 48 hours and a high chance within
the next 7 days.
The axis of a central Atlantic tropical wave is near 48W from 01N
to 20N. It is moving westward at around 10 to 15 kt. Scattered
moderate and isolated strong convection is noted from 14N to 20N
between 45W and 50W.
The axis of an eastern Caribbean tropical wave is near 68W south
of 20N. It is moving westward at around 15 kt. Scattered moderate
convection is noted from 15N to 17N between 65W and 68W.
...MONSOON TROUGH/ITCZ...
The monsoon trough enters the Atlantic near 18N16W and continues
southwestward through a 1012 mb low near 10.5N35W to 10N40W. The
ITCZ continues from 10N40W to 10N47W. It resumes from 10N50W to
10N61W. Aside from convection described in the tropical waves
section above, scattered moderate and isolated strong convection
is noted from 04N to 10N east of 30W, and from 05N to 09N between
40W and 47W.
...GULF OF AMERICA...
High pressure dominates the Gulf basin. Gentle to moderate
anticyclonic wind flow prevails. Seas are in the 1-3 ft range.
For the forecast, high pressure will dominate the basin through
the week supporting mainly gentle to moderate winds. Winds will
freshen in the N-central and NW Gulf Mon night as the high gets
reinforced. Moderate to locally fresh winds will pulse offshore
the Yucatan Peninsula each night. Winds may increase to moderate
to fresh in the SE Gulf and Straits of Florida by Wed night due to
a passing tropical wave just to the S combined with a stationary
front or coastal trough off the SE U.S. coast.
...CARIBBEAN SEA...
Fresh to strong winds prevail over the south central Caribbean.
Moderate winds are elsewhere E of 80W. Over the western Caribbean,
gentle to moderate winds are noted. Seas are in the 3-5 ft range E
of 80W, and 1-2 ft W of 80W.
For the forecast, a tropical wave in the central Caribbean will
move through the western Caribbean Tue night through Thu night.
Expect fresh winds over the central Caribbean Mon through Tue in
the wake of the tropical wave. Scattered showers and isolated
thunderstorms will accompany the wave. Fresh to strong winds will
pulse in the S-central waters through mid-week. Otherwise, gentle
to moderate trades, and mostly moderate seas will remain through
the week, except slight to moderate seas in the NW Caribbean.
...ATLANTIC OCEAN...
A surface trough extends over the western waters, from 31N74W to
the Straits of Florida. Moderate winds, and seas of 6-8 ft prevail
W of the trough. High pressure dominates the remainder of the
discussion waters N of 20N, anchored by a 1029 mb high centered
near 37N34W. Moderate to fresh winds prevail over the waters N of
15N and E of 50W, where seas are in the 4-7 ft range. Elsewhere,
gentle to moderate winds, and seas of 3-5 ft are noted.
For the forecast west of 55W, the trough will weaken through Mon.
Otherwise, Atlantic high pressure will generally maintain
moderate winds and seas elsewhere across the region through the
week. A tropical wave over the eastern tropical Atlantic is
likely to develop into a tropical depression during the middle to
latter part of this week as the system moves west- northwestward
over the central tropical Atlantic. Regardless of development,
expect increasing winds and building seas over the southeastern
waters by the end of the week.

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
