Caution level winds will be reached tonight, and advisories will be needed beginning Thursday afternoon or Thursday night as seas continue to build and winds shift to the north as a storm system and associated rains along with possible thunderstorms move across the area. Some gale force wind gusts could develop late Thursday afternoon through early Friday afternoon. North to northwest winds Friday night and on into Saturday will weaken, and lighter northwest to west winds will prevail over the weekend.
