Synopsis
Northerly winds will ease slightly and move farther offshore overnight Wednesday. Winds and seas continue to ease into Thursday as a passing weak cold front moves near the area. This will create westerlies for the outer waters which will quickly drive in steep 9 to 11 ft seas starting late Thursday night. The northerlies increase Friday and through the weekend.
