Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...A surface ridge along 27N will maintain fresh to locally strong trades north of Hispaniola and in the Windward Passage through Sun morning. A strong cold front will move south of 31N tonight, extend from near 30N55W to 28N65W to 31N78W Sat morning, then begin weakening Sat night while extending from 25.5N55W to 26N67W to 29N73W. Strong NW to N winds will follow behind the front late tonight through Sat, mainly east of 75W and north of 26N. Large N swell will propagate southward east of 65W Sat through Mon. Looking ahead, a low pressure system should be located near Bermuda on Sun, likely extending a cold front with strong to near gale force winds into the TAFB waters well to the NE of the Bahamas on Sun. This system should then move E between 28N and 31N through Mon. Gale force winds are possible Sun night N of 29N and E of 57W. NE swell producing large seas is expected behind this front, mainly affecting waters N of 27N and E of 65W through the middle of next week.
