Heavy showers and thunderstorms expected for portions of the state

Weather Blog

Flash Flood Watch is in effect for Ni’ihau, Kaua’i and O’ahu until Wednesday afternoon.

A wet pattern is unfolding across the western end of the state due to an out of season upper low and surface front positioned to the west-northwest.

Warm and humid conditions with increasing rain chances are anticipated beginning tonight as this upper low begins to drift toward the islands.

Although the threat for heavy rain and storms will focus over the western end of the state through Tuesday, a gradual eastward shift down the island chain will become a possibility by midweek.

Winds will remain light out of the south to southeast, which will allow the land and sea breeze regime to continue.

A drying trend along with a return of a more typical trade wind pattern is not anticipated until late Thursday through the upcoming weekend.
