Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...A strong cold front extends from near 31N67W across the central Bahamas to the Straits of Florida. Intensifying low pressure off the Mid-Atlantic coast will pull this front across the waters through Thu night. Gale force SW winds and very large seas will prevail ahead of the front N of 27N this evening. Gale force NW gusts are expected behind the front over the northern waters through tonight. Gale force winds may develop over the far NE portion Fri into early Sat as the associated low pressure system dives SE and passes just north of the forecast waters. Northerly swell will produce large seas across the SW N Atlantic waters through the weekend, then gradually decay early next week. ATLC waters from 27N to 31N W of 77W .TONIGHT...N winds 10 to 20 kt.
