.SYNOPSIS...Moderate to fresh SW winds, moderate seas and
scattered thunderstorms are active south of central and eastern
Cuba tonight ahead of a trough over the northwest Caribbean.
High pressure over the central Atlantic will support moderate to

but a weak pressure pattern will maintain gentle breezes and
slight seas elsewhere.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...A 1006 mb gale center, remnants of Jerry, is
currently near 27N63W and strong convection is noted over the
eastern semicircle. Winds to gale force and rough to very rough
seas will persist north of 27N between 57W and 63W through late
Sun. Meanwhile, a 995 mb gale center is centered off the Carolinas
and extends a cold front to South Florida. A tight pressure
gradient behind the front supports strong to near gale-force N
winds and rough to very rough seas. Fresh to strong S winds and
rough seas are also noted ahead of the front to 73W. Winds and
seas will diminish through early Mon as the low pressure moves
north of the area. Looking ahead, a cold front will move
southward to the east of Bermuda Tue into Wed, bringing fresh to
strong W to NW winds and rough seas to the waters north of 28N
and east of 60W.
