Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...A cold front extending from 31N56W SW to the Windward Passage will merge with a reinforcing cold front that extends from 31N68W to 29N75W tonight. The merged front will move E of the area by Sun evening. Fresh to near gale force W to NW winds between both fronts and N of 28N will continue to affect the northern offshore waters through Sun morning, however rough seas affecting the offshore waters E of the Bahamas and N of 24N will gradually diminish through Wed.
