027 FZNT31 KNHC 300802 OFFN20 Marine Weather HF Voice Broadcast NWS National Hurricane Center Miami, FL 402 AM EDT Thu May 30 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 moderate pressure gradient between high pressure north of the area and low pressure near Colombia will maintain fresh to strong trade winds over the south-central Caribbean and Gulf of Honduras through Fri night. Winds will become moderate to fresh Thu through Fri as the pressure gradient slackens some. The pressure gradient will increase Fri night behind a tropical wave that is currently in the far southeastern part of the Caribbean leading to fresh to strong trade winds across the central basin through early Mon. A tropical wave currently over the western Caribbean near 86W is producing scattered to numerous showers and thunderstorms over the southwestern Caribbean and over Honduras and northern Costa Rica. The wave will move inland the Yucatan Peninsula and northern Central America today. Smoke from agricultural fires over Central America is causing reduced visibilities over portions of the Gulf of Honduras. NW Caribbean W of 85W .TODAY...E winds 10 to 15 kt.

Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...Relatively weak surface ridging over the region is allowing for moderate or lighter winds to exist over the forecast waters. A cold front will move off the southeastern U.S. coast today, move across the western half of the area through Fri night, and across the remainder of the forecast waters through late Mon. High pressure building in behind the front will tighten the pressure gradient across the region, bringing moderate to fresh winds across waters north of 20N. Moderate seas can also be expected with these winds. Conditions will slightly improve by early next week north of 27N. ATLC waters from 27N to 31N W of 77W .TODAY...NW winds less than 10 kt.
