Gale force winds will continue through Fri before diminishing from north to south through Fri night. Very rough seas will accompany the winds on Fri before diminishing through Sat morning. Otherwise, moderate to locally fresh N to NE winds will prevail across the rest of the basin, with winds increasing to fresh to strong speeds late tonight and Fri, including through the Florida Straits, as high pressure builds over the southeastern United States.
