Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...A cold front extending from near 31N69W to West Palm Beach, Florida 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 east winds across the Bahamas starting Thu night. Winds diminish 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, weaken as it reaches from near 31N69W to 27N73W, and as a weakening stationary to South Florida by late Sun and from near 31N59W to 26N73W by late Mon. The strong southwest winds are forecast to lift north of the area Sun. ATLC waters from 27N to 31N W of 77W .TONIGHT...NE winds 10 to 15 kt. Seas 5 to 7 ft. .THU...NE winds 10 to 15 kt.
