Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...A cold front stretching from near 31N69W to the
Straits of Florida near 24.5N81W will extend from near 26N55W to
23N67W and stationary to South Florida Fri evening. Strong winds
and rough seas will impact waters north of 27N on both sides of 
this front through Fri evening. A stronger cold front is expected
to move across the waters off northeast Florida by late Sat, 
preceded by strong to gale force southerly winds east of Florida 
on Sat. This front is forecast to reach from near 31N74W to South
Florida early Sun, from near 31N59W to the central Bahamas early
Mon and from near 24N55W to 24N68W early Tue. On Sat night

another strong cold front over the waters east of NE Florida,

elsewhere north of 27N and west of 65W.
