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 surface trough extending from near the Mouth of the 
Mississippi to the Bay of Campeche will slowly move W and move 
inland over Texas and Mexico by Fri night. This feature is 
supported by a mid to upper-level trough and will dissipate after
landfall as the mid to upper-level trough weakens. Showers and 
thunderstorms will be possible in the vicinity of the trough. 
Surface troughs moving W from the Yucatan Peninsula will produce 
fresh to locally strong winds over the eastern waters of the Bay 
of Campeche from sunset to around midnight. A ridge extending SW 
across Florida over the NE Gulf will gradually lift northward and
generally support moderate ESE to SE return flow over the basin 
through Mon night.

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

Fresh to locally strong trades are expected in the central
Caribbean and the Gulf of Honduras through Mon night. Scattered
showers from a tropical wave will move across the SE Caribbean
today and the central Caribbean Fri. A NE to SW oriented ridge 
extending across most of the N Atlantic will weaken as an area 
of low pressure centered near 38N52W drifts southward through 
Sun morning to near 29N46W, then slowly lifts back N Sun and 
Mon. As a result trade winds over the tropical N Atlantic will 
diminish slightly during the next several days.

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

Winds will pulse to strong speeds near the northern coast of 
Hispaniola each night through Mon night. Otherwise, trade winds 
across the region will gradually diminish through Mon night as
the ridge over the western the Atlantic weakens in response to 
low pressure and associated troughing shifting S over the NE 
waters extending and lifts northward.
