The National Weather Service in Honolulu has issued a Flash Flood Warning for Hawaii Island until 8 p.m.

At 4:52 p.m. weather radar and rain gages indicated that heavy rain is persisting over the slopes in the South Kohala and North Kona districts. Gulches crossing Mamalahoa Highway (Route 190) between Puuanahulu and Waimea were at risk of overflowing. Some of these gulches also flow near Waikoloa Village and into Puako. Rainfall may continue for several more hours.

Locations in the warning include, but are not limited to, Waikoloa Village, Puako, Puuanahulu, Pohakuloa Training Area, Pohakuloa Camp, Waikii, Mauna Lani and Waikoloa Beach.

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.

This warning may be extended should heavy rains continue.
