000 FZNT31 KNHC 042116 OFFN20 Marine Weather HF Voice Broadcast NWS National Hurricane Center Miami, FL 516 PM EDT Sun Aug 4 2024 Marine Weather HF Voice Broadcast for the Tropical N Atlantic from 07N to 19N W of 55W, the N Atlantic from 19N to 31N W of 55W including the 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 W of 55W .SYNOPSIS...Tropical Storm Debby is near 27.7N 84.4W at 5 PM EDT, and is moving north at 10 kt. Maximum sustained winds are 55 kt with gusts to 65 kt, and the minimum central pressure is 992 mb. Debby will strengthen to a hurricane near 29.1N 84.4W Mon morning. The tropical cyclone will continue to pull away from the area tonight. A tropical wave located east of the Lesser Antilles, with axis along 56W, continues to produce an area of showers and thunderstorms, with fresh to strong winds and moderate to rough seas near the northern end of the wave axis. Environmental conditions appear generally favorable for some slow development of this system during the week as it moves quickly westward at around 15 to 20 kt, crossing the Windward Islands on Mon, and moving into the central and western Caribbean by the mid to latter part of this week.
