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

.SYNOPSIS...A stationary front extending across western Cuba
into the Yucatan Channel will dissipate Fri. High pressure
building north of the area behind the front will continue to
support moderate to fresh NE winds across the basin, reaching
fresh to strong speeds over the NW Caribbean and offshore of
Colombia Fri night through Sun evening. Fresh to strong NE winds
will also develop south of Hispaniola Sat evening through Mon.
Looking ahead, the winds and seas over the central and eastern
basin will diminish Mon night into Tue morning as the high
pressure shifts eastward ahead of the next cold front forecast
to enter the NW Caribbean Tue afternoon.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...A cold front extending from 31N61W to the central
Bahamas to western Cuba will continue to weaken as it moves 
eastward today, reaching central Cuba by this evening.
Afterward, the front will stall and dissipate through late Fri, 
ahead of a reinforcing cold front expected to move off the NE 
Florida coast late Fri. Strong to near-gale force winds and rough
seas will accompany the front mainly north of 26N Fri night, 
likely reaching gale force with very rough seas early Sat morning
through Sat evening over the offshore waters between 60W and 
75W. Winds will further diminish Sun in most areas as high 
pressure builds eastward behind the front as it exits to the east
of region. Looking ahead, fresh to strong southerly winds will 
return to the waters off NE Florida and north of the Bahamas Sun 
night into Mon, rapidly reaching gale force speeds ahead of the 
next cold front expected to move off the coast Mon evening. The 
front will extend from Bermuda to the central Bahamas by Tue 
morning and from 31N60W to the southern Bahamas offshore waters 
Tue night.
