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.

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 between 55W and 64W

.SYNOPSIS...Gales will finally end this afternoon off the coast
of Colombia, before winds quickly pulse back to gale force
tonight. Thereafter the pressure gradient responsible or the
high winds will lessen some, allowing winds to decrease to
strong levels into mid-week. High pressure building SW toward
the Caribbean will result in strong E and NE winds over much of
the Central and Eastern Caribbean through tonight, before the
high moves to the east and weakens, leading to lesser winds for
most of the area. Long period N swell has arrived to the
Antilles and this is creating very large seas and hazardous
marine conditions the Tropical North Atlantic.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...Strong winds over the far southern waters will
diminish today. Very large seas in N to NE swell will continue 
into Mon, resulting in large breaking waves and dangerous surf
conditions on Atlantic beaches of the Greater Antilles and Turks
and Caicos Islands. A cold front will move off the SE U.S. coast
today, reach a line from Bermuda to the central Bahamas to 
central Cuba by late Mon, then stall from east of Bermuda
through the Turks and Caicos Islands and through the Windward 
Passage on Tue. A reinforcing surge of high pressure building 
down the east coast of the U.S. in the wake of this cold front 
will bring strong to near gale force winds over waters N of 25N 
Tue through Thu. Gales appear likely Tue night N of 28N and W of 
77W.
