Gulf of Mexico, Caribbean Sea, northern sections of South
America, and Atlantic Ocean to the African coast from the
Equator to 32N. The following information is based on satellite
imagery, weather observations, radar and meteorological analysis.

Based on 1800 UTC surface analysis and satellite imagery through
2345 UTC.

...SPECIAL FEATURES...

Gulf of Mexico Gale Warning: As of 2100 UTC, a strong cold front
extends from 31N80W to Tampa Bay, Florida to the central Bay of
Campeche. Gale force winds are west of the front and south of
22N. Seas are presently to 12 ft. Winds will diminish to below
gale force on Tue. Please read the latest High Seas Forecast at
https://www.nhc.noaa.gov/text/MIAHSFAT2.shtml for more details.

...MONSOON TROUGH/ITCZ...

The monsoon trough axis extends from the west coast of Africa near
07N12W and continues to 05N20W. The ITCZ begins near 05N20W and
continues along 03N36W to the coast of N Brazil near 01S50W.
Scattered moderate convection is from 01N-08N between 06W-36W and
from 04N to 10N between 36W and 50W.

GULF OF MEXICO...

A strong cold front is over the Gulf of Mexico extending from
Tampa Bay to the Bay of Campeche. Gale force winds are behind the
front over Veracruz adjacent waters. Winds and seas diminish Tue
as the front stalls and starts to dissipate from near Tampa Bay,
Florida to the south central Gulf Tue. Another cold front will
move into the NW Gulf Tue night and cross the basin by Thu, and
will bring brief gales offshore Veracruz Wed. Winds and seas
diminish through Fri as high pressure builds across the northern
Gulf in the wake of the second front. A third front will move into
the northwest Gulf by Sat night. See the Special Features section
above for further details on the gale warning.

CARIBBEAN SEA...

Strong dry air subsidence from middle and upper levels is
supporting fair weather conditions across most of the area while
weakening high pressure north of the area supports modest winds
and seas. By Wed, high pressure will begin to strengthen to the
north, and pulses of strong winds will develop at night offshore
of Colombia. A weakening cold front will move slowly SE across the
Yucatan Channel and western Cuba Thu night through Fri. Strong
high pressure north of the front will support fresh to strong NE
tradewinds across much of the area Fri and Sat.

ATLANTIC OCEAN...

Strong S winds are ongoing N of 28N W of 74W ahead and behind of
a cold front that extends from 31N79W to Tampa Bay to the SW Gulf
of Mexico. This front will move eastward across the waters north
of 27N through Wed. Meanwhile, a deep layer trough will remain
nearly stationary along about 57W-58W through Tue before drifting
westward and weakening Tue night through Thu. The next cold front
will move into the NW waters Wed night then slide slowly SE and
reach from near Bermuda through the NW Bahamas to W Cuba Fri
morning, then drift southeast of the area through late Sat.
