The National Weather Service in Honolulu has extended the flash flood warning for Kona until 12:45 a.m. Saturday (Sept 12).

At 9:40 p.m. weather radar indicated very heavy rain affecting coastal eeward Kohala between Mahukona and Kawaihae with rainfall with rates up to three inches per hour likely leading to flash flooding and ponding on roadways. Meanwhile heavy rain and thunderstorms over the Kona Coast and slopes has eased but Hawaii Island police report significant flooding impacts continue especially near Honaunau where water and debris are on roadways.

Locations in the warning include, but are not limited to, Captain Cook, Honaunau and Kealakekua as well as leeward Kohala between Kawaihae and Mahukona.

A flash flood warning means that flooding is imminent or occurring in streams, roads and low lying areas. Move to higher ground now.

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.

This advisory may need to be extended beyond 12:45 a.m. if these heavy rains persist.
