118 FZNT31 KNHC 030310 OFFN20 Marine Weather HF Voice Broadcast NWS National Hurricane Center Miami, FL 1110 PM EDT Wed Apr 2 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...Strong to near-gale force E to NE winds will pulse offshore of Colombia and through the Gulf of Venezuela each night and morning into this weekend. Very rough seas peaking near 13 ft will occur near and to the west of the strongest winds in the south-central Caribbean. Elsewhere, strong to near-gale force SE winds will likely pulse each evening into the early morning hours in the Gulf of Honduras through this weekend. Rough seas will occur in association with these winds. Otherwise, a strong pressure gradient between high pressure over the central Atlantic and the Colombian low will support widespread fresh to strong trade winds across the rest of the basin through Sat, including through the Mona and Windward Passages. Rough seas of 8 to 11 ft will prevail over the southwestern, central and eastern basin, including across the tropical Atlantic waters into the Caribbean passages, during this time. Looking ahead, the pressure gradient will relax for Sun into early next week, supporting moderate to locally fresh trade winds across much of the Caribbean, with pulsing strong winds occurring offshore of Colombia.

Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...Fresh to strong trade winds will occur south of 25N, including through the Florida Straits, through Sat morning as a strong pressure gradient prevails between high pressure in the central Atlantic and the Colombian low. Very rough seas of 8 to 11 ft will accompany these winds. The pressure gradient will relax for the second half of the weekend into next week as a low pressure system moves through the central Atlantic, weakening the ridge. As a result, moderate to locally fresh trade winds and locally rough seas are expected across this region into early next week. A long-period N swell associated with the central Atlantic low pressure system will push into the northeastern waters, north of 20N and east of 65W, by early next week, leading to rough seas. Looking ahead, fresh to locally strong S winds are slated to develop off the coast of central and northern Florida on Sun ahead of a cold front moving through the southeastern United States. The cold front is forecast to move off the coast early next week, and winds will turn to the W and NW behind the front. ATLC waters from 27N to 31N W of 77W .OVERNIGHT...SE winds 10 to 20 kt.
