Marine Weather HF Voice Broadcast

NWS National Hurricane Center Miami, FL

328 PM 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...High pressure north north of the area supports

moderate to fresh easterly trade winds over the central and

eastern Caribbean. The gradient will loosen some tonight leading

for these winds to be confined to the southeastern Caribbean.

Moderate to fresh northeast winds are expected in the the lee

Cuba, northwestern Caribbean and in the the Windward Passage

tonight and Fri night and in the Windward Passage Sat night and

Sun night. Gentle to moderate trade winds are expected over the

area through the forecast period, except for mostly fresh winds

in the south-central Caribbean. The combination of a trough

along 80W/81W south of 20N with the base of a western Atlantic

upper-level that reaches to western Caribbean has resulted in

the development of scattered showers and thunderstorms from the

eastern tip of Cuba to the Windward Passage. Scattered showers

and isolated thunderstorms are over the waters between eastern

Cuba and Jamaica. All of this activity is translating

east-northeastward.

Synopsis for the the SW N Atlantic including the Bahamas



.SYNOPSIS...The gradient between high pressure over the western

Atlantic and relatively lower pressure in the Caribbean Sea is 

allowing for generally moderate to fresh east winds to be south

of about 25N, including the approaches to the Windward Passage.

A surface trough is expected to soon form north-northeast of 

Hispaniola. The pressure gradient between the ridge and the 

trough will support pulsing strong east to southeast east of the 

trough, and moderate to fresh northeast to east winds west of the

trough. Presently, an upper trough is over the western Atlantic.

Numerous showers and thunderstorms are east of this trough. The 

trough is expected to help promote the formation of weak low 

pressure along the soon to form surface trough on Fri. The low 

will track east-northeastward Fri through Sat, and weaken back 

into a trough while exiting the area on Sun. High pressure will 

then take precedence over the entire area early next week. 

Moderate to fresh south winds are forecast to develop over the 

waters east of northeastern Florida Tue and Tue night.
