N Atlantic waters late tonight through Mon night. Winds and seas

Wed. A cold front will move into the NW Caribbean Mon night,
bringing fresh to strong N winds to the waters W of 80W through

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...A cold front extending from near 22N61W to 21N67W
westward into the Florida Straits will stall over the Greater 
Antilles tonight, then dissipate on Sun. Strong to near gale
force winds will continue behind the front into Sun. Very large
seas in N to NE swell will prevail through Mon, resulting in
large breaking waves and dangerous surf conditions along the
Atlantic beaches. Another cold front will move off the SE U.S.
coast Sun, then pass SE across the forecast waters through early
next week. Expect strengthening NE winds and building seas
across the northern waters through midweek following frontal
passage.
