Heavy rainfall caused flooding in various areas throughout the island Monday afternoon and evening.

As of early Tuesday morning, the National Weather Service cancelled the Flood Advisory for the Big Island as conditions have begun to improve islandwide with just light rain falling in isolated areas.

All major highways and roadways were reopened overnight, including Kuakini Highway and Hualalai Road and Akoni Pule Highway at Kawaihae Harbor.

The road closure on Kupuna Road, or Old School Road, in Ahualoa has remained in effect as hazardous conditions remain. Crews are working to clear the area so the road may reopen.

Motorists are advised by Hawai’i County Civil Defense to drive carefully as ponding, runoff, and other dangerous conditions may still present a threat.
