Synopsis for Caribbean Sea and Tropical N Atlantic from
07N to 19N W of 55W

.SYNOPSIS...A strong pressure gradient from the Bermuda High to
the Colombian Low will continue to produce gale-force winds N of
Colombia through early Sat morning, while fresh to near-gale
trades prevail across most of the basin, including Atlantic
passages and the Gulf of Honduras. Winds will pulse once again
to gale-force over the waters S-central Caribbean on Sat
night/early Sun. Rough to very rough seas will accompany these
winds. By early next week, as the weakening Bermuda High shifts
eastward, trades across the Caribbean will be reduced to
moderate to fresh. A cold front may reach the northwest
Caribbean Tue with winds shifting from southeasterly to
northerly. The front may then stall and dissipate over the NW
Caribbean mid-week.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...A strong Bermuda High will continue to force fresh
to strong trades south of 23N/24N through tonight. As the
Bermuda High weakens on Sat through early next week, fresh to
strong trades will be restricted to the SE Bahamas and the
Windward Passage, while over the NE waters a front or frontal
trough will rotate through bringing fresh to strong winds Sat
through early Sun. At the same time, a large N swell will start
impacting the waters east of 60W and will subside late Tue into
mid-week. Fresh to strong S winds will develop off the coast of
northeast Florida Sun night and Mon ahead of a cold front moving
through the southeastern United States. The front is forecast to
move off of the coast Mon night, and reach from Bermuda to
eastern Cuba by mid week, followed by fresh to strong NE winds
and moderate to rough seas.
