Marine Weather HF Voice Broadcast for the Tropical N Atlantic
from 07N to 19N W of 55W, the N Atlantic from 19N to
31N W of 55W including the Bahamas, and the Caribbean Sea.

Seas given as significant wave height, which is the average
height of the highest 1/3 of the waves. Individual waves may be
more than twice the significant wave height.

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

.SYNOPSIS...A frontal boundary will move into the far northeast
Caribbean and stall through Sat, then dissipate. High pressure
will build in the wake of the front across the western Atlantic
into Sat. Large, long-period northerly swell will also accompany
the front, impacting the Atlantic passages into the northeast
Caribbean Sat, the Atlantic waters east off the Leeward Islands
starting Sat night, and the waters east of the Windward Islands
by early Sun before subsiding into Mon. The pattern will also
support moderate to fresh trade winds over the eastern and
south- central Caribbean, with stronger winds pulsing off
Colombia through early next week.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...A mostly stationary front extends from 31N41W to 
northeast Hispaniola will move little through Fri, ahead of a 
reinforcing front developing east of the Bahamas. Winds to gale 
force and rough to very rough seas follow the developing 
reinforcing front across the waters between northeast Florida
and Bermuda, and these winds and seas will move 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.
