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...

A broad surface low over the Yucatan peninsula is expected to
develop and potentially become a tropical cyclone as it moves
slowly northward through Monday. System may evolve by Friday
morning into a Central American Gyre structure with a large area
of cyclonic winds of fresh breeze to near gale, but lacking a
strong inner core characteristic of a tropical cyclone. However,
global model guidance is fairly aggressive in spinning the
system up to a tropical cyclone before its center reaches the
U.S. Gulf coast in three to four days. Strong winds and building
seas are likely primarily east of the tropical low center in the
NE Gulf. Winds are kept at a peak of 30 kt and seas of 12 ft in
the forecast for now. However, an option that may be pursued
tonight or tomorrow is to issue oceanic gale warnings before
tropical cyclone (or potential tropical cyclone) advisories are
issued.

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

A broad surface low over the Yucatan peninsula will drift
northward into the Gulf of Mexico Friday. Fresh to locally
strong SE winds and peak seas near 8 ft are expected the NW
Caribbean Friday and Saturday as this low potentially develops
into a tropical cyclone. High pressure in the central Atlantic
will maintain fresh to strong tradewinds in the Caribbean
through Saturday with strongest winds along the coast of
Colombia before weakening on Sunday and Monday.

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

Moderate to fresh tradewinds are expected south of  27N through
Monday.
