Marine Weather HF Voice Broadcast
NWS National Hurricane Center Miami, FL
1120 PM EDT Fri May 24 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...A very pronounced deep-layer trough that extends
from the Windward Passage SW to northern Costa Rica will lift
E-NE across Hispaniola through Sat night. Active weather east of
the trough will gradually shift NE into the Atlantic through Sat
night. A rather weak pressure pattern across the area will
maintain generally moderate trade winds across the basin, except
for moderate to fresh winds over the NW part of the sea through
late Sun night. Afterwards, moderate to fresh trade winds are
expected over the basin through the middle of next week, except
for light to gentle winds over the northern part of the NW
Caribbean. A low latitude tropical wave is currently in the
Tropical N Atlantic near 56W. The wave will cross the Windward
Islands late Sat afternoon into Sat night, move through the E
Caribbean Sun through Mon night, then become ill-defined as it
approaches the central Caribbean Tue. Gusty winds and active
weather are expected with the wave. Smoke due to agricultural
fires in Central America may persist across the Gulf of Honduras
over the weekend.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...A trough extends from near 29N61W WSW to weak low
pressure of 1012 mb near 27N69W to E Cuba. Scattered showers and
thunderstorms are presently in the NE semicircle of the low to
57W. Regarding the low, although environmental conditions are
not conducive, some slight subtropical or tropical development
is possible over the next couple of days while the system moves
generally NE. Otherwise, relatively weak high pressure will
remain over the region for the next few days. The associated
gradient will support moderate winds and seas are possible north
of the Bahamas and off northeast Florida by Mon night as the high
pressure shifts eastward ahead of a cold front that is expected
to move off the southeastern U.S. coast Mon night, move across
the waters east of northern Florida early on Tue, reach from near
31N79W to east-central Florida early on Wed and from near 31N78W
to 29N79W and stationary to east-central Florida Wed night.
