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 stationary front extends from Fort Myers, Florida, to 25N90W,
to the Bay of Campeche. This front will remain stationary through
Wed, before reinforcing cool and dry air pushes the front through
most of the basin Thu. The front will then stall again and
dissipate Fri. High pressure in its wake will shift eastward
through Sat night as a cold front reaches eastern Texas. Fresh to
strong southerly winds will develop over the NW and central Gulf
late Fri through Sat.

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

Fresh to strong trade winds over the central Caribbean will
diminish by late in the week as high pressure over the central
Atlantic shifts eastward, except near the coast of Colombia
where these winds will persist through the week.

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

A weak cold front extending from 31N73W to near West Palm Beach,
Florida, will stall into Wed, before moving SE as a cold front.
Thu into Fri this front will again stall from SE of Bermuda
through the SE Bahamas and western Cuba. It will lift back N as
a warm front Sat and Sat night as another cold front approaches
the southeastern U.S. coast preceded by fresh to strong southerly
winds, and with possible scattered showers and thunderstorms.
