Wet weather, strong winds, possible thunderstorms on the horizon

A strong cold front is expected to bring wet weather to the state starting Sunday into Monday and Tuesday. The front is forecast to quickly move down the island chain Sunday night and then stall over the central islands Monday, with a flash flood watch taking effect Sunday evening for Oahu and Maui County.

Heavy showers and isolated thunderstorms will be possible along and ahead of the front, followed by cool and strong northerly winds that could reach wind advisory speeds. The moisture from the stalled front will keep wet conditions in the forecast into Wednesday. A wet trade wind weather pattern will set up around Thursday.

Surf will remain large and dangerous into Sunday, with a high surf warning extended through Tuesday morning for north and west shores of Niihau, Kauai, Oahu and Molokai and the north-facing shores of Maui. There’s also a high surf advisory for the north and west shores of the Big Island. This is for a new northwest swell that will push surf back up to warning levels Monday, but this swell is expected to be smaller, and wind conditions will be poor.

Surf will remain on the small side for south and east shores. For mariners, a small craft advisory is posted for all Hawaiian coastal waters.
