Synopsis for Caribbean Sea and Tropical N Atlantic from

.SYNOPSIS...A tight gradient associated with strong high
pressure north of the area will maintain fresh to strong trades
and high seas over the central and eastern Caribbean as well as
over the tropical Atlantic waters through Mon morning as a cold
front moves into the western Atlantic. The front will move into
the far western Caribbean Sea tonight, reach from west-central
Cuba to the northeast part of Honduras by early Mon afternoon,
from eastern Cuba to near the border of Honduras and Nicaragua
early on Tue, then begin to weaken as it reaches from the
Windward Passage to central Costa Rica by early Tue evening and
from the eastern Dominican Republic to near 13N79W by Wed
afternoon and dissipate by late Wed night. Strong northwest
winds will follow in behind the front along the coasts of
Honduras and Nicaragua diminishing to mainly fresh winds on Wed.
Winds near the coast of Colombia will pulse to near gale force
again tonight.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...A stationary front extending from 23N65W to the 
southeastern Bahamas will become diffuse by early this evening. 
Strong high pressure to the north of the front will continue to 
allow for strong northeast to east winds over the waters through
this morning. Low pressure slowly moving northward over the 
northeastern Gulf of Mexico will move off the southeast U.S. on 
Mon, then move slowly eastward through Tue, then in a southeastward
motion through Thu. Gale-force winds are expected over the 
waters east of northern Florida to near 75W beginning tonight and
through late Mon afternoon. A cold front trailing from the low 
will move across the area Mon through Tue night, followed by 
strong west to northwest winds and building seas. The building 
wave heights are expected to mainly be east of the Bahamas.
