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...Strong to near-gale force E to NE winds will pulse
offshore of Colombia and through the Gulf of Venezuela each night
and morning into this weekend. Very rough seas peaking near 13
ft will occur near and to the west of the strongest winds in the
south-central Caribbean. Elsewhere, strong to near-gale force SE
winds will likely pulse each evening into the early morning hours
in the Gulf of Honduras through this weekend. Rough seas will
occur in association with these winds. Otherwise, a strong
pressure gradient between high pressure over the central Atlantic
and the Colombian low will support widespread fresh to strong
trade winds across the rest of the basin through Sat, including
through the Mona and Windward Passages. Rough seas of 8 to 11 ft
will prevail over the southwestern, central and eastern basin,
including across the tropical Atlantic waters into the Caribbean
passages, during this time. Looking ahead, the pressure gradient
will relax for Sun into early next week, supporting moderate to
locally fresh trade winds across much of the Caribbean, with
pulsing strong winds occurring offshore of Colombia.

Synopsis for the the SW N Atlantic including the Bahamas
.SYNOPSIS...Fresh to strong trade winds will occur south of 25N,
including through the Florida Straits, through Sat morning as a
strong pressure gradient prevails between high pressure in the
central Atlantic and the Colombian low. Very rough seas of 8 to
11 ft will accompany these winds. The pressure gradient will
relax for the second half of the weekend into next week as a low
pressure system moves through the central Atlantic, weakening the
ridge. As a result, moderate to locally fresh trade winds and
locally rough seas are expected across this region into early
next week. A long-period N swell associated with the central
Atlantic low pressure system will push into the northeastern
waters, north of 20N and east of 65W, by early next week, leading
to rough seas. Looking ahead, fresh to locally strong S winds
are slated to develop off the coast of central and northern
Florida on Sun ahead of a cold front moving through the
southeastern United States. The cold front is forecast to move
off the coast early next week, and winds will turn to the W and
NW behind the front.
