NWS National Hurricane Center Miami, FL
515 PM EDT Sun May 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...A weak and narrow Atlantic ridge extends westward
along 24N/25N and into the NW Bahamas. The associated pressure
gradient between the ridge and lower pressure over SE Mexico is
supporting fresh to strong E to SE winds across the Gulf of
Honduras, and fresh to locally strong E winds in the south-
central Caribbean. The Winds in the Gulf of Honduras will
diminish to fresh speeds Mon morning. The fresh to strong E
winds in the south-central Caribbean will shift eastward to
offshore of NW Venezuela through Tue night and diminish early on
Wed. A rather vigorous deep layer trough will dig southward
across the western Caribbean Mon night through Fri, and support
very active weather over the central portions E of 80W Tue
through Fri, perhaps a little longer. This feature is likely to
induce a surface trough in the central Caribbean. Fresh to
strong E to SE winds will develop in the central Caribbean Tue
and shift eastward through Thu while diminishing to mostly fresh
speeds, but remain gusty. Smoke due to agricultural fires in
Central America continues across the Gulf of Honduras, but
appears to be thinning out some.

Synopsis for the the SW N Atlantic including the Bahamas
.SYNOPSIS...A weak frontal trough extends from 31N74W to inland
South Florida near Stuart. A narrow high pressure ridge extends
E to W to the south of the trough along 24N/25N and into the NW
Bahamas. The trough will slowly continue southward through Tue.
Scattered to numerous showers and thunderstorms along and near
the trough will shift south with the trough affecting the waters
east of florida to the Bahamas and south of about 28N. Behind
this feature, a new front will sink southward into the waters
offshore of Georgia and NE Florida early Mon, and move
southeastward and stall from near 31N72W to SE Florida late Tue.
A trough will develop southeast of the weakening front and extend
into the central Bahamas early on Wed, and drift eastward
through Fri night. Low pressure is expected to form along the
trough near 24N68W Thu evening and move NE through Fri night.
