Flash Flood Watch

The National Weather Service in Honolulu has issued a Flash Flood Watch for Kona, Ka‘u, North and East Kohala along with interior portions of Hawaii Island through Thursday afternoon (Sept 15). This watch is also for Maui County.

Deep tropical moisture and an upper level trough will result in a threat of heavy rainfall and flooding.

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.
