Heavy rains, thunderstorms possible for western half of state

More rain is possible across the western half of Hawaii tonight, according to National Weather Service forecasters, with heavy showers and thunderstorms in store for Kauai and Oahu.

A flash flood watch for Kauai County and Oahu began at noon today due to unstable atmospheric conditions, and is effective through late tonight.

Today highs ranged from 83 to 88 degrees Fahrenheit. Lows tonight range from 70 to 75 degrees.

In Honolulu, scattered showers, with thunderstorms were possible. The east, northeast winds will range from 7 to 15 mph, with gusts as high as 21 mph.

Rainfall amounts between a tenth and a quarter of an inch were expected, with higher amounts possible due to thunderstorms.

A flash flood watch means that conditions are favorable for flash flooding, which is life threatening. The NWS warns the public not to cross fast-flowing water in a vehicle or by foot.

A small craft advisory for Maalaea Bay and Pailolo and Alenuihaha channels remains in effect through 6 a.m. Thursday.

Tradewinds, and drier weather, are expected to return Thursday, but the trades are expected to shift Saturday afternoon, bringing tropical moisture over the eastern half of the state. Increasing humidity and showers are expected Saturday night and Sunday.
