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 gale-force winds N of
Colombia until around sunrise, with another round forecast
tonight. Rough to very rough seas will accompany these winds.
Fresh to near-gale trades will prevail across most of the
remainder of the basin, including Atlantic passages and the Gulf
of Honduras. By early next week, as the weakening Bermuda High
shifts eastward, trades across the Caribbean will be reduced to
moderate to fresh. A cold front may reach the northwest
Caribbean Tue with winds shifting from southeasterly to
northerly behind it. The front may then stall and dissipate over
the NW Caribbean mid-week.

winds through tonight. At the same time, a large N swell will
