Synopsis for Caribbean Sea and Tropical N Atlantic from
07N to 19N between 55W and 64W

.SYNOPSIS...The tail of a cold front will move into the NW
Caribbean Thu morning, reach from central Cuba SW to the
vicinity of northern Belize by Thu evening, then stall and
weaken from near the Windward Passage to near 18N85W by Fri
night. Moderate to fresh northerly winds will follow in behind
the front affecting mainly the Yucatan Channel and Belize
adjacent waters through early Fri. Fresh to strong NE winds will
pulse off the coast of Colombia at night through the forecast
period, however increasing in areal coverage and reaching near
gale-force speeds Mon night as high pressure builds N of the
area in the wake of the front. Surface high pressure N of the
area will also support the development of fresh to strong NE
winds in the Windward Passage Sun evening through early Wed.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...A strong cold front coming off the coasts of Georgia
and NE Florida will enter the far NW waters tonight. The front
will reach from Bermuda to central Cuba by Thu evening, from
near 31N62W to the Turks and Caicos Fri evening, then across the
E and SE forecast waters through Mon. Ongoing gale-force 
southerly winds E of the front north of 30N between 74W and 77W 
will diminish late tonight. Strong to near gale-force winds 
elsewhere E of the front N of about 27N will diminish Thu night 
while fresh to strong west winds will follow the front N of 29N. 
Rough seas on either side of the front N of 27N will shift to E 
of 70W during the upcoming weekend and into early next week. 
Numerous showers and thunderstorms ahead of the front are over 
the waters N of 27N and W of 75W. This activity will continue to 
shift eastward through Thu. A reinforcing cold front will quickly
move across the area from late Fri night through the upcoming 
weekend, followed by fresh to strong west to northwest winds N of
27N. High pressure will develop off the coast of Georgia on Mon 
and associated ridging will support moderate to fresh winds in 
the Great Bahama Bank and the Caribbean approaches.
