Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...A cold front will move off the northeast Florida coast tonight, reach from near 31N72W to the central Bahamas Sun morning, from near Bermuda to 25N72W and to just northwest of Haiti Sun night, from near 31N62W to 20N72W early Mon, from near 31N55W to 26N63W and stationary to 20N69W Mon night and weakening stationary from near 26N55W to 20N69W Tue. Fresh to strong southwest winds are forecast ahead of the front north of about 26N. High pressure will build across the region in the wake of the front. A tight gradient between the high pressure and the front is expected to 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 Wed and Wed night 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.
