Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...The Bermuda High is inducing fresh to strong trades near the Greater Antilles and mainly gentle winds elsewhere. These conditions will prevail through early Sun, before the high moves to the east and winds relax. A cold front will move off the SE U.S. coast Sun night and continue eastward, bringing strong to near gale winds on both sides of the front mainly north of 28N. Low pressure is likely to move northeastward off the SE U.S. coast Tue, bringing another potential for strong to near gale winds on Wed. Large N swell impacting the Atlantic zone from 19N-22N between 55W-65W will diminish on Sun. ATLC waters from 27N to 31N W of 77W .TODAY...S winds 10 to 15 kt.
