The National Weather Service in Honolulu has issued a Flash Flood Watch for Hawaiian Islands from Sunday morning through Monday afternoon (Aug 8).

Abundant moisture from the remnants of Tropical Cyclone Howard and an upper trough moving near the islands will bring a conducive environment for heavy rain and thunderstorms. Saturated grounds from recent rain events will exacerbate the threat of flash flooding from the forecast rainfall. The best chances for flash flooding will be over the northern end of the state.

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.
