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...A 1020 mb high pressure near Bermuda and its
associated ridge supports moderate to fresh easterly trade winds
over the central and eastern Caribbean. The ridge is expected to
slide eastward and weaken on Thu, reducing the areal coverage
and limiting these winds to the SE Caribbean by Thu evening.
Scattered showers and thunderstorms currently affecting eastern
Cuba, Hispaniola, and adjacent passages will expand in coverage
tonight into Thu supported by a surface trough extending along
78W. The pressure gradient between this feature and a weak ridge
will also support moderate to fresh NE winds in the lee Cuba, NW
Caribbean and the Windward Passage Thu night 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 1020 mb high pressure near Bermuda and its
associated 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 on Thu, 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
Sat afternoon.
