HONOLULU (HawaiiNewsNow) -

The Big Island is under a Flash Flood Warning through Thursday evening as unstable weather affects much of the state.

At about 5:30 p.m. radar showed rain falling at 3 to 4 inches an hour in Puna.

A Flash Flood Warning for Oahu, meanwhile, has been cancelled.

A Flash Flood Warning means flooding is imminent or occurring in streams, roads and low-lying areas.

Meanwhile, Oahu, the Big Island and Maui County are under a Severe Thunderstorm Watch.

The National Weather Service said severe thunderstorms can produce damaging winds and destructive hail.

"Unsettled weather can be expected across portions of the state through Friday as an upper level disturbance passes over the island chain," National Weather Service forecasters said.

At about 3 p.m., a strong thunderstorm was located upslope from Mililani and Wahiawa. 

The state also remains under a Flash Flood Watch.

And a Winter Storm Warning is up for the Big Island summits above 12,000 feet. Officials say the summits should expect 3 to 6 inches of snow, high winds and poor visibility.
