Marine Weather HF Voice Broadcast
NWS National Hurricane Center Miami, FL
932 AM EDT Tue Apr 9 2024

Marine Weather HF Voice Broadcast for the Tropical N Atlantic
from 07N to 22N between 55W and 64W, the SW N Atlantic S of
31N W of 65W including 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 between 55W and 64W

.SYNOPSIS...High pressure will build across the western Atlantic
through Wed, tightening the pressure gradient across the region.
This will result in fresh to strong winds expanding in areal
coverage across most of the central Caribbean, pulsing to near
gale-force at night off of Colombia through the next several
nights/early mornings. The building high pressure will also
support fresh to strong winds in the Windward Passage, south of
Hispaniola, and in the Gulf of Honduras. Winds will start to
diminish the end of the week as the high pressure shifts eastward
and well NE of the region. Looking ahead, a cold front is
expected to reach the Yucatan Channel Thu night, then stall and
weaken over the NW Caribbean late Fri.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...Large NW swell will prevail across the NE waters
through tonight before shifting E of the area. High pressure in
the far western Atlantic will drift to near Bermuda by Wed
night, then shift E Thu and Fri. The associated ridge will
support moderate to fresh winds across the Great Bahama Bank and
the Caribbean approaches through tonight, becoming fresh to
strong Wed through Thu. Fresh southerly winds will develop
offshore of Florida and N of the Bahamas on Wed evening and
increase to strong to near gale-force Wed night through Thu,
ahead of an approaching cold front. The front is expected to
cross the Florida Peninsula Thu night, with gales possible Thu
night N of 30N and E of the front. The front will reach from
31N74W to the NW Bahamas Fri morning, and from near Bermuda to
the central Bahamas Sat morning.
