Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...A cold front extending from near 31N75W to inland Florida near Cape Canaveral will slowly move southeastward through Fri, at which time it will reach to along 22N/23N. It will weaken and dissipate Sat. Fresh to strong winds and higher seas are forecast north of 29N in the vicinity of the front today, with moderate to fresh winds elsewhere in the vicinity of the front. High pressure building in the wake of the front will tighten the pressure gradient, generating fresh to strong northeast to northeast to east winds across the Bahamas starting Thu night. Winds diminish during Sat as fresh to strong southwest winds develop over the waters offshore northeastern Florida in advance of the next cold front. This cold front is expected to reach from near 31N77W to West Palm Beach, Florida late Sat night and weaken as it reaches from near 31N69W to 27N75W and weakening stationary to South Florida by late Sun. NE swell will build seas to around 8 ft east of the Bahamas by the end of the week. ATLC waters from 27N to 31N W of 77W .THIS AFTERNOON...N winds 10 to 20 kt.
