Corected SW N Atlantic Including the Bahamas section

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 extending from Fort Myers, Florida to 26N90W 
and to southern Texas will begin to lift back north as a warm 
front late tonight through Saturday. A new cold front will then 
enter the NW Gulf Sat afternoon, and move across the rest of the 
Gulf through Sun evening. High pressure in the wake of the front 
will slide eastward through Tue night allowing for fresh to 
strong southerly flow to set up over the western Gulf.

...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 slightly into the weekend as high pressure over the
central Atlantic shifts eastward, except near the coast of
Colombia where these winds will persist into early next week, 
but within a rather small area.

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

A weakening cold front extends from just east of Bermuda to 
27N73W, where it becomes stationary to the central Bahamas and 
to the Straits of Florida. A second cold front extends from near 
31N70W to West Palm Beach, Florida. The second front will merge 
with the remnants of the first front early on Fri from near 
31N67W to the central Bahamas and to the Straits of Florida. A 
strong cold front is expected to approach the southeastern U.S. 
coast Sat night, move over the northwest waters late Sat night 
into early Sun, and across the waters northeast of the Bahamas 
through late Mon night while weakening. Fresh to strong 
southerly winds will develop over the northwest waters Sat and 
Sat night, and shift eastward over north-central and northeast 
waters through Sun night. Scattered showers and thunderstorms, 
some possibly strong, are expected ahead of this front.
