Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...A cold front extends from near 21N50W W-SW through 
the 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 gale-force as they shift to
the northeast forecast waters Fri afternoon through night. 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 73W early this morning,
and will dominate regional waters through Sat night before
beginning to slowly subside. The next cold front is forecast to
move off the southeastern U.S. coast by Fri evening, 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 expected ahead
of the front Sat through Sun, with gales developing behind the
front early Sun through early Mon. Yet another cold front is
expected to move off the southeastern U.S. coast early Mon and
reach from near 31N63W through the central Bahamas by late Tue.
