000 FZNT31 KNHC 010918 OFFN20 Marine Weather HF Voice Broadcast NWS National Hurricane Center Miami, FL 518 AM EDT Wed Nov 1 2023 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...Shower and thunderstorm activity remains disorganized in association with a trough of low pressure (AL97) over the central Caribbean Sea. Environmental conditions are forecast to become slightly more conducive for development in a couple of days, and a tropical depression could form during the latter part of this week while moving generally westward over the central and southwestern Caribbean Sea. Otherwise, a strong cold front will enter the NW Caribbean this morning, reach from E Cuba to the Gulf of Honduras Thu morning, then drift westward Fri morning, before dissipating on Sat. Strong to near gale NE winds and rough seas will follow the front through Fri night before diminishing on Sat. Fresh to strong winds are also expected across the central Caribbean late Thu into Fri due to the pressure gradient between AL97 and strong high pressure N of the area.
