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
0300 UTC.
...SPECIAL FEATURES...
Gulf of America Gale Warning: A cold front extends southwestward
from the Florida Straits to the Yucatan Peninsula and southern
Mexico. Near-gale to gale force northerly winds behind this front
near Veracruz, Mexico will gradually decrease to between fresh
and strong after midnight tonight. Seas at 10 to 12 ft will also
subside and become 7 to 9 ft by Tue afternoon.
Please refer to the latest High Seas and Offshore Waters Forecasts
issued by the National Hurricane Center at the website
https://www.nhc.noaa.gov/text/MIAHSFAT2.shtml and
https://www.nhc.noaa.gov/marine/offshores.php for more details.
...MONSOON TROUGH/ITCZ...
A monsoon trough enters the Atlantic near the coastal border of
Sierra Leone and Liberia, then extends southwestward to 04N20W.
An ITCZ continues from 04N20W to 02N30W to 02N46W. Scattered
moderate convection is noted near the ITCZ from 00N to 03N
between 32W and 38W.
...GULF OF AMERICA...
Please see the SPECIAL FEATURES section about a Gale Warning.
A cold front extends southwestward from the Florida Straits to
the Yucatan Peninsula and southern Mexico. Widely scattered
showers and isolated thunderstorms are seen near and up to 50 nm
south of the front. Outside the Gale Warning area, fresh to strong
northerly winds and seas of 8 to 10 ft are present at the
southwestern Gulf, including the western Bay of Campeche. Gentle N
to NE winds and 3 to 5 ft seas in moderate N to NE swell are noted
across the Florida Straits and near the Texas coast. Moderate to
fresh N to NE winds and seas at 6 to 8 ft prevail for the rest
of the Gulf, including the eastern Bay of Campeche.
For the forecast, the aforementioned cold front will stall from
the Straits of Florida to the Yucatan Peninsula on Tue. Fresh to
strong N to NE winds outside the Gale Warning area behind the
front will diminish to between moderate and fresh over the
southeastern and south-central Gulf on Tue, with light to gentle
winds expected over the remainder of the Gulf. Seas will also
subside on Tue as the front stalls near the Yucatan Peninsula and
eventually dissipates around midweek. Looking ahead, weak high
pressure will build over the basin later this week, supporting
gentle to moderate winds and slight seas.
...CARIBBEAN SEA...
A surface trough is triggering scattered showers and isolated
thunderstorms over the Yucatan Channel and near western Cuba. A
1021 mb high at the central Atlantic near 24N45W sustains a fair
trade- wind regime across much of the Caribbean Sea. Moderate to
fresh E winds and seas of 5 to 7 ft dominate the south-central
basin. Light to gentle winds and 1 to 3 ft seas stay at the
northwestern basin and near Costa Rica and Panama, including the
Gulf of Honduras. Gentle to moderate NE to E winds and seas at 4
to 6 ft prevail elsewhere in the Caribbean Sea.
For the forecast, moderate to occasionally fresh trade winds and
moderate seas are expected over the central and eastern basin
through Tue as weak ridging prevails over the central Atlantic.
Winds may pulse to strong in the Gulf of Venezuela and offshore
of northern Colombia by Tue night, and locally rough seas may
develop near and to the west of these winds. A tightening pressure
gradient between a weakening cold front approaching the
northwestern basin and low pressure in the south-central basin
will support fresh to strong trade winds and rough seas in the
central basin beginning on Wed and into the upcoming weekend.
Winds may approach near gale-force offshore of Colombia late Wed.
Elsewhere, a persistent E swell will continue to lead to rough
seas over the Atlantic waters and passages of the Lesser Antilles
into early Wed before seas slightly subside. New mixed N and E
swell is expected to bring rough seas over these same waters
starting late Wed night.
...ATLANTIC OCEAN...
A weakening cold front runs southwestward from a 1006 mb low
south of Bermuda across 31N65W to the central Bahamas. Widely
scattered moderate convection is evident near and up 40 nm south
of the boundary. Convergent trade winds are triggering scattered
moderate convection from 08N to 10N between 32W and 38W. Refer to
the Monsoon Trough/ITCZ section at the beginning for additional
convection in the Atlantic Basin.
Fresh to strong SW to NW winds and seas at 7 to 10 ft are seen
near and behind both cold fronts, north of 27N between 52W and
the northeastern Florida/southern Georgia coast. Otherwise, a
1021 mb high near 24N45W is dominating the Atlantic north of 23N
between 35W and the Florida/southern Georgia coast with gentle to
moderate clockwise winds and seas of 6 to 9 ft in moderate to
large northerly swells. For the tropical Atlantic from 07N to 23N
between 35W and the Lesser Antilles, moderate to fresh with
locally strong NE to E winds and 6 to 9 ft seas are present. For
the remainder of the Atlantic west of 35W, gentle to moderate
southerly winds and 5 to 7 ft seas are found.
For the forecast west of 35W, the cold front will continue
eastward through late Tue night, preceded by fresh to strong
SW winds north of 27N through Tue. Rough seas in W swell east of
73W will continue to expand toward the central Atlantic into early
Tue as very rough seas over 12 ft will be possible north of 30N
and east of 64W by Tue morning. A second and stronger cold front
extending from near 31N73W to the NW Bahamas and to South Florida
will quickly shift eastward through Tue night overtaking the first
front. The front will be followed by fresh to strong NW winds,
north of about 26N and west of 68W into late tonight. A new set of
N swell will support rough seas over the northwest tropical
Atlantic by late tonight, before merging with the aforementioned
rough seas in the central Atlantic on Tue. Winds will diminish
from west to east through Tue night, with rough seas slowly
subsiding through late week. Looking ahead, fresh to locally
strong SW winds and rough seas may develop offshore northern
FLorida starting Wed as a low pressure system moves off the east
coast of the U.S.

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.
