.SYNOPSIS...Fresh to strong SE winds over the northwest
Caribbean will diminish this afternoon and tonight, as a cold
front moves SE into the southeast Gulf of Mexico. Fresh to
strong N winds and large swell will follow the front as it moves
in through the Yucatan Channel Thu. The front will continue to
move SE and reach from central Cuba to the Gulf of Honduras Thu
evening, and from eastern Cuba to eastern Honduras Fri morning,
as wind and seas begin to diminish behind the front. Looking
ahead, expect fresh to strong NE winds across the Windward
Passage Fri night through late Sat, as the front stalls from
central Hispaniola to northeast Nicaragua. Expect fresh to
strong NE winds and rough seas across the central Caribbean Sun
as high pressure builds north of the region and to the east of
the northern Bahamas, in the wake of the front.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...Fresh to strong winds N of 27N, and large northerly 
swell, are behind a cold front extending from 31N59W to the 
central Leeward Islands. E of the front, a broad band of strong to
gale-force SE winds extends across the far NE offshore waters, 
and are expected to diminish below gale-force this afternoon. The 
front will move slowly eastward and weaken through Thu, as 
associated low pressure currently just SW of Bermuda moves 
southeastward to near 29N59W around midday, and stalls near 
26N59W on Thu. The front will move eastward of the regional waters
and gradually weaken by Fri, as the low pressure weakens, and 
lifts northward again, passing to the east of Bermuda early Sat. 
Meanwhile, fresh to strong winds and rough seas will follow a new 
cold front that will move off the NE coast of Florida Thu, reach 
from Bermuda to eastern Cuba late Fri morning, and from 31N55W to 
central Hispaniola Sat morning. Looking ahead, the front will 
stall and weaken from 31N55W to the Leeward Islands by late Sun. 
Winds and seas will diminish in most areas W of the front as high 
pressure builds along 27N in the wake of the front.
