The National Weather Service in Honolulu has issued a Flash Flood Watch for all Hawaiian Island through Tuesday afternoon (Aug 28).

Trailing deep tropical moisture left over from Lane will bring the potential for additionally heavy rainfall through Tuesday. Any additional heavy rainfall over these already highly saturated grounds could quickly lead to flash flooding.

Heavy rainfall could result in low spots in roads becoming dangerous and impassible due to severe runoff. Debris in streams and gulches may clog bridges and culverts resulting in dangerous 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. Remember, if lightning does threaten your area, the safest place to be is indoors.

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.
