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...The pressure gradient between an Atlantic high
pressure ridge extending along roughly 30N and lower pressure
across South America is supporting fresh to locally strong trade
winds over the central Caribbean, along with mainly moderate
seas. Winds and seas will diminish slightly Thu through Sat as a
pair of tropical waves move through the basin. The tradewinds
and associated seas will increase again Sat night into Mon as
high pressure builds again in the wake of the tropical waves.
