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.

Synopsis for Caribbean Sea and Tropical N Atlantic from
07N to 19N W of 55W

.SYNOPSIS...A strong pressure gradient from the Bermuda High to
the Colombian Low will continue to produce fresh to near gale
trades across the Caribbean through Sat afternoon. The winds
should reach gale force briefly tonight just north of Colombia.
From Sat night through early next week, the Bermuda High weakens
contributing toward reduced winds over the basin. However,
strong trades will still continue north of Colombia, south of
Hispaniola, and over the Gulf of Honduras on Sun. By Mon and Tue
as the weakened Bermuda High shifts eastward, trades across the
Caribbean will be reduced to only moderate to fresh. Looking
ahead, a cold front may reach the NW Caribbean Tue with winds
shifting from southeasterly to northerly.
