Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...A cold front extending from 31N60W to the central
Bahamas and eastern Cuba will continue to weaken as it moves
eastward, reaching from 31N55W to the SE Bahamas and eastern
Cuba this morning. Afterward, the front will stall and gradually
dissipate through late today, ahead of a reinforcing cold front 
expected to move off the NE Florida coast late today. Strong to 
minimal gale force winds and rough to very rough seas will 
accompany the front mainly north of 29N late Fri through Sat. 
Then, winds will diminish from west to east on Sun, but a swell 
event will continue to affect most of the waters E of 70W through
Sun night. Looking ahead, fresh to strong southerly winds will 
return to the waters off NE Florida and north of the Bahamas Sun 
night into Mon, rapidly reaching gale force speeds ahead of the 
next cold front expected to move off the coast Mon evening. The 
front will extend from 31N70W to western Cuba by Tue morning, and
from 31N57W to SE Bahamas and eastern Cuba Tue night. Another 
swell event with very rough seas will follow the front.
