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...

High pressure over the northeast Gulf will shift southeast today
to the Bahamas. Associated surface ridge will move into the
southern Gulf through Fri ahead of a cold front moving into the
northern Gulf by late Fri. The front will stall across the
northern Gulf Fri night, then dissipate through Sat night. High
pressure building north of front over the Carolinas will support
increase SE winds and building seas across the western Gulf Sat
into Sun, with strong SE winds possible in the northwest Gulf by
Sun night as low pressure forms over northern Mexico. Winds and
seas diminish across the Gulf into Mon as the high shifts
farther east and a weak cold front moves into the coastal waters
of Texas through Mon night.

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

High pressure north of the area will continue to support fresh
to strong winds over the south central Caribbean, with winds
pulsing to gale force during the overnight hours off Colombia
through the next several nights.

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

A cold front from 28N65W to 28N78W will move east of the area
tonight. Another front will move into the waters between Bermuda
and northeast Florida Fri evening, reaching along 27N by Sat
evening, along 23N east of the Turks and Caicos Islands by Sun
evening, then stalling along 20N off the coast of the Dominican
Republic by Mon evening. High pressure will build over the area
in the wake of this front.
