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

.SYNOPSIS...A surface ridge extending southward from the eastern
Gulf of Mexico will sustain moderate to fresh N to NE winds and
moderate seas across the western Caribbean through early Fri.
The high pressure will build eastward into the western Atlantic
through early next week, causing these winds and seas to also
shift eastward into the central Caribbean. In addition, winds at
the south-central basin will pulse to strong at night through
early next week.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...A cold front extending from 31N42W to northeast
Hispaniola will move little through Fri, ahead of a reinforcing 
front that will develop east of the Bahamas. Winds to gale force
and rough seas will follow the developing reinforcing front
across the waters between northeast Florida and Bermuda today,
and southeast of Bermuda tonight and Fri. The fronts will merge
late Fri and shift east of the area by early Sat. Farther west,
expect SW gales and rough seas off northwest Florida late Fri
night, ahead of another front that will move off the coast early
Sat. This front will reach from Bermuda to Jupiter Inlet,
Florida Sat night, and will exit east of the area through Mon.
As with the earlier front, gale force winds and rough seas will
follow this front across the waters between northeast Florida
and Bermuda through Sun. Looking ahead, winds and seas will
diminish as high pressure builds over the basin Sun into Mon.
