HONOLULU (HawaiiNewsNow) - A flood advisory that had been in effect for parts of Oahu was allowed to expire at noon.

However, forecasters at the National Weather Service said a moist and unstable atmosphere will trigger thunderstorms and locally heavy rainfall capable of producing flash flooding.

At 10:30 a.m., when the flood advisory was still in effect, rain gages at Palisades showed heavy rain falling at 2 inches per hour.

Meanwhile, a flash flood watch was canceled for the Big Island, however forecasters say locally heavy rainfall remains possible through the Week.

The National Weather Service also issued a winter weather advisory for the Big Island summits which is in effect until 6 a.m. Wednesday. 

The summits could see snow and freezing rain.
