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...Fresh to strong winds will prevail across the
central Caribbean through late Thu. Disorganized showers and
thunderstorms persist in association with a trough of low
pressure located in the southwestern Caribbean Sea.
Environmental conditions appear marginally conducive for
development of this system over the next couple of days, and a
tropical depression could form by this weekend as the system
starts moving northeastward across the western and central part
of the Caribbean Sea. Regardless of development, this system
will produce areas of heavy rain, and locally gusty winds, over
portions of the central and western Caribbean through the end of
this week. There is a medium chance of tropical cyclone
development in the next 48 hours.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...A frontal boundary extends from 31N47W to the 
central Bahamas to the Florida Straits. Fresh to strong NE-E 
winds prevail N of the front. High pressure will build in the 
wake of the front N of the area today. This will support an area 
of strong to near- gale winds over the waters N of 25N and W of 
70W beginning tonight. A broad area of low pressure may develop 
over the waters W of 75W by the end of the week, with the strong 
to near- gale force winds shifting to the waters N of 27N and W 
of 70W toward the end of the week. Gale force winds are expected 
N of 27N Thu afternoon through Fri, before lifting N of 31N Fri 
evening. The low will drag a frontal boundary across the waters 
in its wake through the upcoming weekend.
