Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...A cold front extends southwestward from the eastern Azores across 31N36W to 23N45W, then continues as a stationary front to the Leeward Islands. The whole frontal boundary should become stationary tonight, and then dissipate through Sat evening. A reinforcing cold front is forming from 31N48W southwestward to 26N62W this afternoon. This feature will keep fresh to strong with locally near-gale winds north of 24N and east of 63W through late tonight. Meanwhile, another cold front is exiting into the Atlantic waters from the southeast U.S. coast this afternoon. It 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 are going to persist across the western Atlantic through midweek next week. ATLC waters from 27N to 31N W of 77W .TONIGHT...W winds 15 to 25 kt.
