000 FZNT31 KNHC 271514 OFFN20 Marine Weather HF Voice Broadcast NWS National Hurricane Center Miami, FL 1114 AM EDT Thu Oct 27 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 drift westward tonight through Sat then lift northward into the Atlantic Sun. A tropical wave along 68W continues to interact with this feature to produce scattered to numerous thunderstorms between 63W and 68W this morning. The tropical wave will move slowly W through the weekend. An area of low pressure is expected to form over the eastern Caribbean Sea this weekend, possibly related to the southern portion of an existing trough of low pressure over the area. Thereafter, 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 into the central Caribbean Sea. This system has a low chance of development in the next 48 hours and a medium chance in the next 5 days. NW Caribbean W of 85W .THIS AFTERNOON...Variable winds less than 10 kt.

Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...Scattered to numerous showers and thunderstorms persist across the Atlantic waters between 62W and 68W, supported by a deep layered upper trough along about 70W. At the surface, a trough of low pressure stretches from Hispaniola northward along 69W-70W. These features are expected to remain nearly stationary through early Sat and maintain active thunderstorms to the E. A surface low pressure system is forecast to emerge along the northern portion of the trough axis later today or tonight, and environmental conditions appear marginally conducive for some subtropical development. A subtropical depression could form during the next couple of days while the system moves northward, then meanders to the west or southwest of Bermuda. Over this weekend, upper-level winds are forecast to become less conducive for development. This system has a medium chance of development in the next 48 hours and 5 days. Associated large NE swell will impact the northern waters W of 70W Fri night through the weekend. ATLC waters from 27N to 31N W of 77W .THIS AFTERNOON...Variable winds less than 10 kt.
