Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...A weakening cold front extends from 31N49W to 23N58W then stationary to 22N70W. The front will remain nearly stationary along 22N-23N through this evening while weakening. Large and long period northerly swell, with seas up to 15 ft follow the front. This swell event will continue to propagate across the forecast waters reaching the Bahamas and the Greater Antilles today. Fresh to strong trade winds are expected through the Bahamas, Straits of Florida and Windward Passage through late this week. Looking ahead, the next cold front will move off NE Florida late Fri night. A low pressure may develop along the frontal boundary just off the coast of Georgia by Sat evening. The low will move NE, dragging the cold front across the forecast region Sat night through Mon night.
