The National Weather Service in Honolulu has issued a flash flood watch for Hawaii Island and Maui beginging 6 p.m. Saturday (Aug 22) through 6 p.m. Monday (Aug 24).

A vast area of deep moisture to the east of Tropical Storm Kilo will overspread the Hawaii Island and Maui this weekend. This tropical moisture interacting with island terrain could result in localized, intense, slow-moving downpours leading to flash flooding.

This watch may need to be expanded to other islands as details of Tropical Storm Kilo’s effects become more clear.

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.
