The National Weather Service in Honolulu has issued a flash flood watch for Hawaii Island until 6 p.m. Thursday (Aug 6).

Moisture from Tropical Storm Guillermo will move over Hawaii Island through Thursday bringing the possibility of heavy rain and flash 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.

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