The entire state can expect humid conditions and a chance for locally heavy downpours and isolated thunderstorms that hit Hawaii island and parts of Oahu on Tuesday.

“The deepest moisture is going to be moving over Oahu during the day,” with portions of Maui County and Kauai being affected, National Weather Service lead forecaster Jon Jelsema said Tuesday.

A trough of low pressure originating from the tropics brought the moisture to the islands, and was pushing westward off Hawaii island Tuesday.

On Tuesday night a flash flood warning for Windward Oahu was issued, and a flash flood watch was in effect on Hawaii island.

Hawaii island Tuesday was hit the hardest by torrential downpours in different locations, including the leeward side.

At 4:36 p.m. radar showed heavy showers north of Kailua- Kona and along windward and southeast slopes of Hawaii island. The rain was falling at rates of 2 inches an hour.

Civil Defense interim Administrator Ed Teixeira said three to four homes reported flooding on the east side of Waimea. The homes are in flat areas where the rain ponded. Rain flooded another Waimea home on Puu Nani Drive.

Workers from the county Department of Public Works delivered sandbags to affected residents, and the Fire Department also responded, he said.

The National Weather Service’s Hilo Airport rain gauge recorded 6.98 inches of rain from midnight Monday until 4:36 p.m. Tuesday, breaking the one-day record of 3.59 inches set in 1982.
