Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...A cold front extends from 29N55W to 23N70W, then curves as a stationary front to near West Palm Beach, FL. The front will weaken today as high pressure builds in east of Florida. Large long-period N to NE swell will continue to affect much of the area for the next couple of days. A large and powerful low pressure system north of the area will bring strong to near gale force W winds tonight through Thu night to the waters east of 65W and north of 27N. Very large seas can be expected in this area. Farther west, fresh to strong southerly winds will develop offshore NE Florida beginning tonight as a strong cold front approaches the southeastern U.S. coast. The front is forecast to move off the coast late Thu, reach from near 31N74W to West Palm Beach, FL early Fri, and from near 31N65W to the Florida Keys early Sat. Scattered showers and thunderstorms are likely to move offshore the Florida coast on Thu. On Sun, a reinforcing cold front is expected to merge with it. The merged front is expected to reach from near 31N62W to the central Bahamas and western Cuba Sun night. The fresh to strong southerly winds will shift eastward across the northern and central waters through Sat and exit the area late Sat. Fresh northwest to north winds will follow in behind the merged front. ATLC waters from 27N to 31N W of 77W .TODAY...SE winds 10 to 15 kt. Seas 7 to 8 ft. .TONIGHT...S winds 10 to 20 kt.
