000 FZNT31 KNHC 110727 OFFN20 Marine Weather HF Voice Broadcast NWS National Hurricane Center Miami, FL 327 AM EDT Thu Apr 11 2019 Marine Weather HF Voice Broadcast for the Tropical N Atlantic from 07N to 22N between 55W and 64W, the SW N Atlantic S of 31N W of 65W including 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 ATLC from 07N to 19N between 55W and 64W .SYNOPSIS...A trough extending from central Cuba to a low pres near 18N83W to NE Honduras adjacent waters will continue to weaken and dissipate Thu evening. A weak ridge to the north will promote only moderate to fresh tradewinds across the Caribbean into Fri. The ridge will strengthen afterwards, thus resulting in fresh to near gale force winds along the coast of Colombia through Mon night. The overall increase in pressure gradient will also result in fresh to strong winds in the Gulf of Honduras through Sun evening, increasing to near gale force at night.

Synopsis for the the SW N ATLC including the Bahamas .SYNOPSIS...A cold front extending from 31N67W to near 29N69W to 29N75W will extend from 31N63W to 24N69W this evening. A ridge building N of the area will tighten the pressure gradient NW of the front, thus resulting in fresh to strong winds and building seas over the north-central and NE waters by Thu night, continuing through Fri as the front moves E of the area. A surface trough, remnants of the front will drift WNW Fri evening through Sat morning supporting the continuation of fresh to strong winds over the NE waters. S winds will increase off northeast Florida late Sun ahead of another cold front expected to move off the coast early Mon, reaching from 31N69W to the northern Bahamas Mon night.
