400 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.

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...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 S 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...1013 mb low pressure just E of 55W near 24.5N53.5W
extends a trough to 20N60W. Otherwise high pressure dominates the
basin. The low and trough will shift ENE into the weekend. High
pressure will otherwise prevail through Sun, with mainly gentle
to moderate winds. A cold front may move into the waters off NE
Florida Sun night into Mon, reaching from 31N69W to the northern
Bahamas early Tue. Moderate to fresh winds may accompany the
front, locally strong near 31N, along with building seas. Winds
may freshen over the SE waters next week as the pressure gradient
tightens there, leading to building seas. Mainly slight to
moderate seas will prevail elsewhere.
