000 FZNT31 KNHC 200801 OFFN20 Marine Weather HF Voice Broadcast NWS National Hurricane Center Miami, FL 401 AM EDT Wed Mar 20 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...Low pressure associated with a frontal system in the SW N Atlc is allowing for a relaxed pressure gradient in the south-central Caribbean. However, fresh to strong winds are expected to pulse at night within 90 nm off the coast of Colombia mainly due to the nocturnal drainage flow. Fresh to strong winds are also possible in the Gulf of Venezuela. Otherwise, the tail of a cold front extends from western Cuba SW to just N of Belize. The front will move SE and stall from central Cuba to NE Honduras adjacent waters by Thu morning and dissipate at night. Gentle to moderate winds will dominate across the remainder basin through Sun.

Synopsis for the the SW N ATLC including the Bahamas .SYNOPSIS...A stationary front extends from 30N62W to 27N68W to a low pressure center near 26N74W then transitions to a cold front that continues to 23N80W into the NW Caribbean. The low will gradually shift NE dragging the cold front SE to the southern Bahamas by this evening. The front will then stall and weaken before dissipating by Thu night. Strong to minimal gale force winds are expected across the NW semicircle of the low center this morning through early Thu. NE swell associated with the front will propagate across the northern waters through Thu. However, swell associated with a reinforcing cold front will prevail through Sun. This second front will extend from near 25N65W to north-central Dominican Republic by Fri evening. ATLC waters from 27N to 31N W of 77W .TODAY...NE winds 10 to 20 kt.
