000 FZNT31 KNHC 010914 OFFN20 Marine Weather HF Voice Broadcast NWS National Hurricane Center Miami, FL 514 AM EDT Wed Sep 1 2021 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...The pressure gradient between a ridge east of Florida and lower pressure over northern Colombia will support moderate to fresh trade winds over the south-central and northwest Caribbean through at least Fri. Similar wind speeds are expected in the Gulf of Honduras at night through the weekend. A broad area of low pressure is producing disorganized shower activity over the southwestern Caribbean Sea. Some slow development of this system is possible over the next couple of days while it moves westward or west-northwestward at 5 to 10 kt toward Central America. Thereafter, land interaction with Central America and the Yucatan Peninsula of Mexico will likely limit further development of this system. NW Caribbean W of 85W .TODAY...SE winds 10 to 20 kt.
