Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...A cold front extends from near 31N67W southwestward to 28N73W and to Miami, Florida. This front will reach from near 31N66W to 27N74W and continue as a stationary front to the Straits of Florida by early Fri, and become nearly stationary from near 28N65W to 25N70W and continue to the Straits of Florida Sat. High pressure will build from the southeastern U.S. behind the front, with the resultant gradient leading to fresh northeast winds to the northwest of the front. A large low pressure system well north of the area will deepen through Fri and continue to generate large northwest to north swell over much of the western Atlantic through Sat. This swell will then begin to slowly subside later on Sat and through Sun. ATLC waters from 27N to 31N W of 77W .TONIGHT...NE winds 10 to 20 kt. Seas 6 to 9 ft. .FRI...NE winds 10 to 20 kt.
