000 FZNT31 KNHC 081600 OFFN20 Marine Weather HF Voice Broadcast NWS National Hurricane Center Miami, FL 1100 AM EST Sat Mar 8 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...Moderate to locally fresh trade winds are expected across the basin this weekend into early next week as high pressure builds north of the area and low pressure prevails over northwestern Colombia. Pulsing strong E to NE winds will occur each night and morning offshore of Colombia and through the Gulf of Venezuela, and locally rough seas will be possible near the strongest winds. Fresh to locally strong SE winds are also expected to pulse in the Gulf of Honduras into early next week. Looking ahead, a cold front moving through the Gulf of America this weekend is slated to enter the northwestern Caribbean early next week, leading to fresh to locally strong N winds and locally rough seas in its wake.

Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...Moderate to locally fresh SW winds will occur east of a cold front in the central Atlantic, extending from 31N52W to just north of Puerto Rico, early this morning as a storm system lifts northeastward away from the forecast waters. Rough seas generated by this storm system will shift eastward across the western and central Atlantic through Sat night, before gradually decaying Sun and Mon. Seas of 12 to 15 ft are expected north of 29N between 68W and 55W through late tonight. Farther west, a strengthening pressure gradient between high pressure east of the Bahamas and a complex low pressure system north of the area will lead to fresh to locally strong SW winds north of 29N between 80W and 60W today. Looking ahead, fresh to strong S to SW winds will develop on Mon off the coast of Florida ahead of a cold front moving through the southeastern United States. The cold front is slated to move off the southeastern coast early next week, leading to widespread strong to near-gale force winds and very rough seas in the wake of the front. Gale force winds will be possible in this region Mon night through Tue. ATLC waters from 27N to 31N W of 77W .TODAY...W winds 10 to 20 kt.
