The National Weather Service in Honolulu has extended the flash flood warning for Hawaii Island until 2:30 a.m. Saturday (March 26).

At 11:17 p.m. weather radar and gages continue to report heavy showers and thunderstorms moving across the north Kona and both Kohala districts. This rainfall falling over already saturated grounds will likely result in additional flooding within the warning area. Emergency management have reported flooding along Highway 270 and Mamalahoa Highway (Route 190) in the Kohala area.

Locations in the warning include but are not limited to Hilo, Kailua-Kona, Kapaau, Honokaa, Honomu, Kamuela, Puuanahulu and Pohakuloa Camp.

A flash flood watch is also in effect for Hawaii Island overnight.

Areas in the watch include, but are not limited to, Kona, Ka‘u, north and east Kohala, Hawaii Island interior areas and mountain summits.

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. Excessive runoff may cause rockslides and mudslides in steep terrain.

Debris in streams and gulches may clog bridges and culverts resulting in flooding outside normal water channels causing damage.

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