Deep tropical moisture surrounding Lane will start to spread rainbands and possible thunderstorms over the Big Island by Wednesday morning, then continuing northward across the state as Lane approaches. Hurricane Lane could bring damaging winds, dangerous surf, and intense, flooding rains to various parts of the state Wednesday through Saturday.
