Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...A cold front extends from 31N72W to just N of West Palm Beach, FL. The front will reach from 31N60W to the SE Bahamas by Mon morning. The northern portion of the front will continue to move eastward through Tue while the southern part will become stationary over the SE waters while weakening. Fresh to strong southwest winds are forecast ahead of the front north of 26N through late Mon. Similar wind speeds from the N and rough seas will follow the front through late Mon. High pressure will build across the region in the wake of the front. 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 while the front emerges off the southeastern United States coast. Fresh to strong winds are expected behind the front and east of northern and central Florida Wed night into Thu. 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.
