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

.SYNOPSIS...A surface trough is moving westward across the
Leeward Islands, producing scattered showers. Building high
pressure north of the Caribbean Sea will support moderate to
fresh easterly winds over much of the basin through early next
week. Locally strong NE winds may pulse at night off NW Colombia
tonight and Thu night. Meanwhile, locally rough seas, in NE
swell, will persist across the NE Caribbean passages into early
next week. Looking ahead, a cold front may approach the NW
Caribbean early next week.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...A cold front stretches from 31N67W to south Florida.
The front will extend from 31N67W to central Cuba by Thu morning,
and from 31N55W to eastern Cuba by Fri morning while dissipating.
High pressure will follow the front. Then, a ridge will dominate
most of the forecast area through the end of the week. The next
cold front is expected to clip the waters offshore of NE Florida
late Fri into Sat, resulting in fresh to strong southerly winds
and moderate to locally rough seas N of 28N and east of 70W.
Conditions will improve Sun, but a stronger cold front reaching
the same area on Mon.
