Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...A cold front extends southwestward from the eastern Azores across 20N50W, then continues as a shearline to the central Lesser Antilles. The entire boundary should become stationary tonight, and then dissipate through Sat evening. A reinforcing cold front is just N of the area from 32N52W southwestward to 31N57W and will sweep eastward across the NE waters tonight through Sat. This feature will keep strong to gale-force winds to the north of 24N and east of 60W overnight. Meanwhile, another cold front is exiting the southeast U.S. coast, and will reach from 31N70W to southern Florida early Sat morning, generating strong to near-gale westerly winds and higher seas from the northwest Bahamas northward. As it moves farther eastward across the western Atlantic waters, it will produce near- gale to gale winds north of 27N and east of 72W through Sun. Successive large northerly swell behind these fronts will persist across the western Atlantic through the middle of next week. ATLC waters from 27N to 31N W of 77W .TONIGHT...W winds 15 to 25 kt.
