Marine Weather HF Voice Broadcast
NWS National Hurricane Center Miami, FL
433 AM EDT Thu May 2 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...Surface ridging N of the area supports moderate to
fresh easterly trade winds over the central and eastern
Caribbean. The ridge is expected to slide eastward and weaken
today, reducing the areal coverage and limiting these winds to
the SE Caribbean by this evening. Scattered showers and
thunderstorms currently affecting eastern Cuba, Hispaniola, and
adjacent passages will expand in coverage today supported by a
surface trough extending along 79W. The pressure gradient
between this feature and the ridge will also support moderate to
fresh NE winds in the lee Cuba, NW Caribbean and the Windward
Passage tonight into Sat night. Gentle to moderate trades are
expected basin-wide the remainder forecast period, except for
fresh winds in the south-central Caribbean.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...A surface ridge extends across the SW Atlantic and
supports moderate to fresh easterly winds S of 25N, including
the approaches to the Windward Passage. The ridge is expected to
slide eastward and weaken today, while a surface trough develops
just N of Hispaniola. The pressure gradient between the ridge
and the trough will support pulsing strong E-SE winds E of the
trough and moderate to fresh NE-E winds W of the trough. The
trough will also amplify the area of showers and tstms currently
affecting the southern Bahamas and the Great Bahama Bank. The
trough is forecast to become a weak low, which will track NE Fri
through Sat, and open back into a trough while exiting the area
on Sun.
