000 FZNT31 KNHC 190800 OFFN20 Marine Weather HF Voice Broadcast NWS National Hurricane Center Miami, FL 400 AM EDT Fri Apr 19 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...Broad high pressure located between Bermuda and the Bahamas will support fresh to locally strong trade winds in the lee of Cuba, Windward Passage, and S of the Dominican Republic at night during the next few days. These winds will gradually diminish this weekend into early next week as a cold front moves across the western Atlantic and the pressure gradient relaxes. A locally tight pressure gradient will support pulsing fresh to locally strong winds near northern Colombia at night. NW Caribbean W of 85W .TODAY...E winds 10 to 15 kt.

Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...1013 mb low pressure just E of 55W near 24.5N53.5W extends a trough to 20N60W. Otherwise high pressure dominates the basin. The low and trough will shift ENE into the weekend. High pressure will otherwise prevail through Sun, with mainly gentle to moderate winds. A cold front may move into the waters off NE Florida Sun night into Mon, reaching from 31N69W to the northern Bahamas early Tue. Moderate to fresh winds may accompany the front, locally strong near 31N, along with building seas. Winds may freshen over the SE waters next week as the pressure gradient tightens there, leading to building seas. Mainly slight to moderate seas will prevail elsewhere.
