Marine Weather HF Voice Broadcast for the Tropical N Atlantic
from 07N to 22N between 55W and 64W, the SW N Atlantic S of
31N W of 65W including Bahamas, and the Caribbean Sea.

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

.SYNOPSIS...Large long-period N to NE swell across the central
Atlantic will be reinforced by another pulse of long-period
swell during the early part of the week. This swell will
continue to pass through the NE Caribbean passages and affect
the Tropical N Atlantic waters during the next few days. High
pressure north of the Caribbean is allowing for gentle to
moderate northeast to east trade winds across the basin, except
for fresh to strong pulsing northeast to east winds offshore
Colombia during the forecast period.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...A cold front from 19N55W to 17N63W will weaken as it
shifts east of the area by late tonight. Large long-period N to 
NE swell will continue to impact the Atlantic waters and
Caribbean Passages between the southeastern Bahamas and the
eastern Caribbean, producing high seas into late Tue.
Long-period NE to E swell is expected to continue affecting the
Florida offshore waters north of 27N during the next few days.
Hazardous marine conditions are likely, especially east of the
Bahamas through late Tue. Looking ahead, fresh to strong
southerly winds are expected to develop offshore NE Florida
beginning late Wed night as a strong cold front approaches the
southeastern U.S. coast. The front is forecast to move off the
coast late Thu, reach from near 31N77W to South Florida early
Fri, and from 31N71W to the central Bahamas and to central Cuba
by late Fri night. The fresh to strong southerly winds will
shift eastward across the northern and central waters, while 
fresh to strong west to northwest winds follow in behind the 
front. Seas will build with these winds.
