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

...GULF OF MEXICO...

Northerly gales and high seas follow a cold front from the
Florida Big Bend to the eastern Bay of Campeche tonight. A
scatterometer pass from 0330 UTC indicated winds to 45 kt off
Veracruz. It is plausible winds have been as high as minimal
storm force through part of the day off Veracruz. Buoy 41055 near
22N94W in the southwest Gulf showed seas to 22 ft during the
afternoon. Farther south, the longer fetch and duration of the
winds supported seas building at least as high as 27 ft. A Jason
altimeter pass from around 0025 UTC indicated seas as high as
29.5 ft near 18.6N 94.3W. This is within 60 nm north of Coatzacoalcos
Mexico, where gusts in excess of 50 kt have been reported.

The front will move very slowly SE overnight then move SE of the
Gulf Thu midday. Winds to gale force may persist off the
northeast coast of Yucatan into Thu afternoon. Winds and seas
will gradually subside through late week behind the exiting
front. Gentle to moderate northerly flow will cover the Gulf Fri,
with high pressure building across the northwest Gulf Sat and
Sun.

...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN
55W AND 64W...

High pressure across the NW Atlc is supporting fresh trade winds
over most of the Caribbean. A scatterometer pass from 23 UTC
indicated fresh to strong NE to E winds in the northern entrance
to the Windward Passage, and fresh easterly winds off Cabo Beata
on the south coast of Hispaniola. A trough across Puerto Rico
extending NNE into the adjacent Atlc will move W across Hispaniola
Wed. The 23 UTC scatterometer pass showed a large area of fresh
to strong trade winds over the tropical Atlantic waters east of
the Leeward and Windward Islands in the wake of the trough. This
will diminish E swell will cover the tropical north Atlantic
through mid week. Strong northerly winds and building seas will
follow a cold front entering the Yucatan Channel this evening.
Fresh northerly winds and seas to 10 ft will spread across the
northwest Caribbean into Fri behind the front, then diminish Fri
into Sat as the front stalls and weakens from eastern Cuba to
eastern Honduras.

...SW N ATLANTIC INCLUDING THE BAHAMAS...

High pressure over the NW Atlc will shift ESE ahead of a cold
front moving off the northeast Florida coast. The front will
reach from near 31N74W to the central Bahamas and central Cuba
late Thu night into Fri. Meanwhile a trough across the NE
Caribbean and adjacent Atlc will move westward across Puerto Rico
tonight, across Hispaniola Wed, and through the southern Bahamas
by late Thu. As the trough reaches the Bahamas along 75W early
Fri it will recurve northward to the east of the central Bahamas
ahead of the cold front, then move north of the area Sat as the
cold front reaches from Bermuda to eastern Cuba.
