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 weak and narrow Atlantic ridge extends westward
along 24N into the central Bahamas. The associated pressure
gradient between the ridge and lower pressure over SE Mexico is
supporting fresh to strong E to SE winds across the Gulf of
Honduras, and fresh to locally strong E winds in the south-
central Caribbean. Strong winds in the Gulf of Honduras will
persist through Sun morning, reaching near gale-force tonight.
Fresh to strong winds will pulse at night in the Gulf of
Venezuela and offshore Colombia through Mon night. High pressure
from the eastern Atlantic will build westward Wed and early Wed
night leading to increasing trade winds over most of the central
and eastern Caribbean as a weak trough materializes over the
western Atlantic. A mid to upper-level trough may bring
increasing tropical moisture to the central and eastern
Caribbean region around mid-week. Smoke due to agricultural
fires in Central America continues across areas of the
northwestern Caribbean, and over the Gulf of Honduras.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...A weak frontal trough extends from 31N58W
southwestward to 26N66W then to 27N72W. The trough will shift 
eastward through late Sun as it weakens further. Moderate to 
locally fresh winds and moderate seas are expected across most
of the area through Sun night as weak high pressure extends E to
W to the south of the trough, roughly along 24N-25N. A new front
will sink southward into the waters offshore of Georgia and NE 
Florida early Mon, and move southeastward and weaken through late
Tue. A trough will extend from near 30N70W to the northern 
Bahamas early on Wed and slowly shift eastward through Thu night,
as possible weak low pressure forms along it.
