Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...A cold front will move off the northeast Florida coast tonight, and move E across the offshore waters through Tue, before weakening. Fresh to strong southwest winds are forecast ahead of the front north of 26N. High pressure will build across the region in the wake of the front. A tight gradient between the high pressure and the front will lead to fresh northeast to east winds south of 30N west of the front from Mon night through Tue night. Looking ahead, fresh to strong southerly winds are expected to develop over the NW part of the area starting Tue afternoon and into early Wed in advance of a stronger cold front. These winds may reach to near-gale force on Wed as they shift to mostly south to southwest in direction while the front emerges off the southeastern United States coast. Fresh to strong winds west are expected west of the front east of northern and central Florida Wed night. The front is forecast to move across the western and central waters Thu and Thu night, with fresh to strong winds on either side of it north and northeast of the Bahamas.
