Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...A cold front extending from 23N55W to 22N70W will weaken and dissipate today. Strong high pressure building in the wake of the front is producing fresh to locally strong NE to E winds north of the front and east of the central and southern Bahamas. Fresh to strong southerly winds prevail offshore northeastern Florida in advance of the next cold front that will move off the coast of the southeastern U.S. tonight. This cold front will move southeast, become stationary from near 31N60W to the NW Bahamas by Mon night, then weaken through Tue night. Fresh to strong winds will continue ahead of the front and also will follow the front as it shift eastward across the waters north of about 29N through Sun before shifting north of the 31N Sun night. Otherwise, fresh to strong winds will continue in the Great Bahama Bank and between Hispaniola and Turks and Caicos through mid-week.
