Forecast: Periods of rain, heavy at times, as we track a front and disturbance tonight into the weekend

HONOLULU (HawaiiNewsNow) - Unsettled weather will persist through the forecast period. Locally heavy rainfall and thunderstorms are possible for Maui and the Big Island through Wednesday evening.

Gusty northerly winds will accompany a cold front that will push through the islands Thursday night through Friday.

Heavy rainfall and flash flooding are possible from Friday into next week. A flash flood watch may need to be posted by the National Weather Service as we get closer to Friday into the weekend.

Let’s talk surf! A moderate northwest swell is slated to hold through Thursday. A large north-northwest swell comes in Friday, peak Saturday.

A high surf warning is very likely for the north- and west-facing shores of most islands. For the other shores, the east-facing shores will see surf trending down as the trade winds weaken.

Surf along south-facing shores will remain flat through the forecast period.
