000 FZNT31 KNHC 020304 OFFN20 Marine Weather HF Voice Broadcast NWS National Hurricane Center Miami, FL 1104 PM 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 could become a little more conducive for some development over the next couple of days before the system moves inland over Central America by this weekend. Regardless of development, this system has the potential to produce heavy rains over portions of Central America late this week and into the weekend. A strong cold front extending from western Cuba southwestward to Belize will reach from eastern Cuba to the Gulf of Honduras Thu morning, then become stationary and dissipate by Sat. Strong to near gale force northeast 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 north of the area. Wind/seas conditions diminish further starting late Sat and into next week high pressure north of the area weakens. NW Caribbean W of 85W .OVERNIGHT...NE winds 10 to 20 kt.
