274 FZNT31 KNHC 042033 OFFN20 Marine Weather HF Voice Broadcast NWS National Hurricane Center Miami, FL Issued by NWS Ocean Prediction Center Washington DC 333 PM EST Tue Mar 4 2025 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 of area combined with the Colombian low will lead to pulsing fresh to locally strong NE to E winds through the Gulf of Venezuela and offshore of Colombia this week, with the strongest winds occurring each night and morning. Moderate to fresh NE winds are expected through early Wed across the Windward Passage and downwind of Cuba as the pressure gradient strengthens between a cold front in the central Atlantic, high pressure offshore of the eastern United States, and the Colombian low. Fresh to locally strong SE winds will be possible this evening into Wed in the Gulf of Honduras. Otherwise, moderate trade winds and slight to moderate seas are expected across the central and eastern Caribbean this week. A cold front will reach the NW Caribbean by Wed night, and extends from central Cuba to near Chetumal, Mexico by Thu morning, and from eastern Cuba to northern Belize by Thu night while weakening.

A shear line is analyzed from 22N70W to 25N77W. The pressure gradient between the front and high pressure just offshore of the eastern United States supports a belt of fresh to strong NE to E winds N of the front to about 27N, including the NW and central Bahamas. At the same time, winds are on increase offshore of Florida ahead of the next cold front forecast to move off the southeastern coast of the US on Wed. Gale force winds and very rough seas are expected on either side of the front and N of 29N through Thu. The front will reach from 31N74W to western Cuba by Wed night, and from 31N63W to eastern Cuba Thu night. N swell behind the front will propagate southeastward through late week, building seas to 18 or or 19 ft north of 25N through Thu, and north of 22N through Fri. Otherwise, moderate to fresh trades and rough seas will prevail south of 25N this week. ATLC waters from 27N to 31N W of 77W ...GALE WARNING... .TONIGHT...SE winds 20 to 30 kt.
