The western part end of a cold front will move southeastward across the NE forecast waters this afternoon and night, and reach along 22N by late Thu. High pressure behind the front will act to freshen NE to E trade winds south of 24N during this period. Looking ahead, large NW swell and near gale-force NW winds are possible on Sat across the NE waters associated with another cold front. The southern part of a cold front will brush the NE forecast waters Sun and Sun night. Otherwise, rather quiet conditions are expected during this time as high pressure settles in over the area.
