Looking Ahead

Tropical Storm Olivia, near Lanai this morning, will pass south of Oahu and Kauai through this evening, then move away to the west. A low aloft north of the islands will move southwest, passing northwest of Kauai on Thursday. Instability from this low combined with moisture from Olivia will keep the weather wet through at least early Friday. A surface high will build far northeast of the state over the weekend and drier air will spread west across the islands.
