Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...A cold front extends from near 22N50W W-SW through 
the northern Leeward Islands to the Caribbean coastal waters of 
Puerto Rico and Hispaniola and will continue to sink southward 
through Fri night and weaken. Fresh to strong W to NW winds N of
25N and E of 70W will increase to strong to near gale-force as 
they shift to the northeast forecast waters by Fri afternoon. 
Large NW to N swell in the wake of the front is producing seas
of 12-17 ft to the N of 20N and E of about 72W tonight, and will
dominate regional waters through Fri night before beginning to 
subside. Looking ahead, the next cold front is forecast to move 
off the southeastern U.S. coast by Fri afternoon, bringing strong
to near gale-force SW to W winds ahead of it to waters east of 
Florida. This front will move eastward across the area during the
weekend, with minimal gale-force winds possible ahead of the 
front. Yet another cold front is expected to move off the 
southeastern U.S. coast Sun night and reach from near 31N68W to 
eastern Cuba by late Tue.
