A Flash Flood Warning for the Big Island has been extended by the National Weather Service until 2 a.m. Tuesday (Dec 31).

The heavy rains and thunderstomrs continue to diminish across the Hamakua Coast, Hilo and Puna areas of the Big Island. Streams remain elevated and ponding is occuring in many areas. Conditions are ripe for more rain and possibly flash floods.

Other locations in the warning area include, but are not limited to, Waipio Valley, Paauilo, Laupahoehoe and Hawaiian Paradise Park.

Police closed Kanoelehua Avenue (Hwy 11) near Waianuhea Place close due to heavy ponding Monday evening with South bound traffic being diverted onto onto East Palai Street and Kilauea Avenue.

Campers and hikers should avoid low lying flood prone areas. People should stay away from streams, drainage ditches and low lying areas prone to flooding. The rainfall and runoff will cause hazardous driving conditions due to ponding, reduced visibility and poor braking action.

Do not cross fast flowing or rising water in your vehicle or on foot. Turn around, don’t drown.
