Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...A cold front extending from 31N78W to east-central Florida will progress rapidly eastward through Fri morning, producing gale-force S to SW winds and rough seas along and ahead of the front, generally north of 29N. Gale force W to NW winds are also expected to develop in the wake of the front overnight off the northeastern coast of Florida, with gale force winds occurring north of 29N through late Thu night. Rough seas in N to NW swell associated with this storm system will propagate southeastward through late week, producing rough seas in excess of 25N through Thu, and north of 21N through Fri. Peak seas of 15 to 19 ft are anticipated north of 27N between 78W and 60W through late this week. The storm system will lift northeastward and away from the forecast waters by Fri, with high pressure building in its wake off the coast of the southeastern United States. Elsewhere, fresh to locally strong NE winds and rough seas will prevail through Thu north of a stationary front in the central Atlantic, extending from 31N41W to 28N58W. Otherwise, moderate to locally fresh E winds and locally rough seas will prevail south of 23N through this weekend. Looking ahead, the next cold front will move off the coast of the southeastern United States late this weekend, producing fresh to locally strong winds and rough seas off the coast of Florida into early next week.
