NWS National Hurricane Center Miami, FL
1050 AM EDT Fri Apr 19 2024

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...Broad high pressure located between Bermuda and the
Bahamas will support fresh to locally strong trade winds in the
lee of Cuba, Windward Passage, and south of the Dominican
Republic at night during the next few days. These winds will
gradually diminish this weekend into early next week as a cold
front moves across the western Atlantic and the pressure
gradient relaxes. A locally tight pressure gradient will support
pulsing fresh to locally strong winds near northern Colombia at
night.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...Weak low pressure of 1013 mb is east of the area
near 25.5N52.5W. A trough extends from the low southwestward to
near 19N60W. Otherwise, high pressure dominates the basin. The
low and trough will shift east-northeastward into the weekend.
Elsewhere, high pressure will remain through Sun, with mostly
gentle to moderate winds across the area. A cold front may move
into the waters off northeastern Florida Sun night into Mon,
reaching from near 31N71W to the NW Bahamas by early Tue, and
from near 31N70W to near 26N75W by late Tue night. Mostly fresh
winds southerly winds are expected ahead of the front, with
locally strong winds near 31N along with building seas. Moderate
to fresh northwest to north winds are expected behind the front.
Winds may freshen over the southeastern waters next week as the
pressure gradient tightens there leading to building seas. Mostly
slight to moderate seas will prevail elsewhere.
