000 FZNT31 KNHC 280859 OFFN20 Marine Weather HF Voice Broadcast NWS National Hurricane Center Miami, FL 459 AM EDT Fri Oct 28 2022 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 deep layered upper trough N to S across the central Caribbean will lift northward into the Atlantic this weekend. Scattered moderate convection are noted across the eastern Caribbean, mainly E of 68W. An area of low pressure is expected to form over the eastern Caribbean this weekend, possibly related to the southern portion of an existing trough of low pressure over the area. Environmental conditions are forecast to be conducive for gradual development, and a tropical depression could form early next week while the disturbance moves generally westward or west-northwestward over the central Caribbean. This system has a low chance of development in the next 48 hours and a medium chance in the next 5 days. Expect scattered showers and thunderstorms to continue through the weekend with the trough and potential developing low. NW Caribbean W of 85W .TODAY...E winds less than 10 kt.

Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...A surface trough over the southwestern Atlantic continues to produce scattered showers and thunderstorms mainly between 60W-70W. A surface low pressure system is forecast to emerge along the northern portion of the trough axis today, and some subsequent development could occur through Saturday. By late Saturday, upper-level winds are forecast to become less conducive for development, and the low is expected to begin interacting with an approaching frontal system. This system has a low chance of development in the next 48 hours and 5 days. A frontal system to the north of the area will interact with the low and could bring moderate to rough seas in NE swell through the weekend west of 70W.
