000 FZNT31 KNHC 180915 OFFN20 Marine Weather HF Voice Broadcast NWS National Hurricane Center Miami, FL 415 AM EST Mon Nov 18 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 Atlantic from 07N to 19N between 55W and 64W .SYNOPSIS...A frontal trough from near the Windward Passage to across Jamaica and to just east of central Nicaragua will slowly dissipate through late Tue. Fresh to strong north winds west of the trough near the coast of central Nicaragua will diminish to mainly fresh winds this afternoon. A tropical wave over the eastern Caribbean with axis near 67W will weaken through Wed as it moves across the eastern part of the central Caribbean. Low pressure of 1008 mb is centered near 19N55W. This low is expected to undergo some gradual development during the next couple of days while it tracks northwestward across the northern Tropical N Atlantic, with potential for it to become a tropical or subtropical cyclone. Expect increasing winds and building seas to begin to impact the northeast Tropical N Atlantic waters tonight and through most of Tue night before these conditions lift north of the forecast waters.
