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 cold front over eastern Texas is approaching the NW Gulf 
coast. Ahead of it, fresh to strong southeast winds are over 
most of the central Gulf. The cold front will move off the Texas 
coast by early this evening, reach from near Mobile, Alabama to 
the SW Gulf early Wed, then stall over the northern Gulf through 
Wed night. The fresh to strong southeast winds will diminish to 
moderate to fresh speeds Wed. The cold front will move 
southeastward across the rest of the basin Thu through Fri. 
Fresh to strong northeast winds will follow in behind the front 
tonight into Wed. Moderate to fresh southeast winds are expected 
across the western and central Gulf this weekend and into early 
next week as high pressure in the wake of the front shifts 
eastward.

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

A ridge north of the area will support moderate trade winds
across much of the basin this week. Fresh to strong SE winds
will continue over the northwestern Caribbean, including the
Gulf of Honduras through Wed night. Hazy sky conditions and
areas of smoke due to agricultural fires in Central America are
noted over most the northwestern Caribbean. These conditions are
likely to change little through the end of the week. Stronger
trade winds are likely over the central Caribbean this weekend
and into early next week as Atlantic high pressure strengthens.

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

The gradient associated with a high pressure ridge near 27N will
support gentle to moderate winds across most of the region 
through Wed night. A cold front is expected to move over the far 
northwest waters early Thu and reach from near 31N76W to the 
Straits of Florida early on Fri. The portion of the front north 
of 25N will continue eastward to the far eastern waters Sat night
while gradually weakening, and as high pressure builds over the 
area into early next week.
