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...

Surface high pressure covers the northern waters. Latest surface
observations indicate that gentle to moderate winds prevail over
the forecast waters, with seas in the 2-4 ft range. The area of
high pressure will retreat eastward by Saturday. This will enable
a cold front to move into the NW waters Sat night. The front
will extend from near Sarasota to the SW corner of Gulf Sun
evening. Fresh to strong N to NE winds will prevail behind the
front, which will build seas to 8-10 ft. Brief gales are possible
along the Mexican coastal waters on Sun. These conditions will
diminish within the next 12 hours as the front progresses.

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

Broad troughing prevails in the central Caribbean along 73W. The
latest surface observations indicate gentle to moderate winds
prevail west of the trough, while light to gentle winds are
noted east of the trough. Seas are 3-5 ft over the Caribbean, and
5-6 ft over the tropical N Atlc waters. Expect for the trough to
drift E into the central Caribbean early this weekend, where it
will stall and weaken through Sun.

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

A cold front extends north of the area over the western Atlantic. A
surface trough extends across in the adjacent waters of the
southern Bahamas. Latest surface observations indicate moderate
to fresh winds prevail near the trough, while gentle to moderate
winds are noted elsewhere. Seas are in the 5-7 ft range over the
northern waters, 4-6 ft over the southern waters outside the
Bahamas, and 2-3 ft west of the Bahamas. The surface trough will
linger over the southeast waters the next few days, and will
weaken this weekend as high pressure builds across the forecast
waters. The high pressure will retreat eastward Sunday enabling
a cold front to move into the NW waters. The front will continue
moving SE across the area through early next week.
