Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...A nearly stationary front extends from near 31N75W southwestward to near West Palm Beach Florida. This front will begin to move east as a cold front later today, and by tonight should be located from around 31N66W to 27N70W to 26N75W. Fri into Saturday, the front will slow down and again become nearly stationary from near 28N65W to 25N70W. High pressure will build from the southeastern U.S. behind the front, with the resultant gradient leading to fresh northeast winds to the northwest of the front. Low pressure will deepen off of the Mid- Atlantic coast through Fri and generate large northwest to north swell over much of the western Atlantic. This swell will slowly subside through Mon night.
