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...The pressure gradient between high pressure over the
central Atlantic and lower pressure over the SW Caribbean will
sustain fresh to locally strong trades over the SW and south-
central Caribbean into tonight, with moderate trades elsewhere
in the central and eastern basin prevailing through the weekend
as the gradient weakens some. A weakening cold front that
extends from central Cuba to Belize will stall tonight then
dissipate Sat. Fresh to strong N winds and rough seas behind it
through the Yucatan Channel will diminish as the front decays. A
very weak pressure gradient across the region Mon and Tue will
lead to tranquil marine conditions.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...A slow-moving cold front from Bermuda to central
Cuba
is followed by fresh to locally strong N winds. This front will
drift E through Sat, then stall Sat night and dissipate Sun. A
tight pressure gradient in the wake of the front will produce
increasing NE winds across the SW Atlantic this weekend. Fresh
to
strong SE winds will develop offshore NE Florida Mon night ahead
of the next cold front forecast to come off the NE Florida coast
Tue night.
