The National Weather Service in Honolulu issued a flash flood watch for Kauaʻi and Niʻihau for the rest of Tuesday till 6 a.m. Wednesday, Dec. 8.
Periods of heavy rainfall are possible over Kauaʻi County tonight as a weakening Kona Low pulls deep tropical moisture over the western end of the island chain.
Flood-prone roads and other low-lying areas may be closed due to elevated runoff and overflowing streams. Urban areas may receive more significant flooding and property damage due to rapid runoff.
Residents are advised to be prepared to take action if a flash flood warning is issued. Head to high ground if experiencing rising waters.
NWS states flash flooding is life-threatening. Do not cross fast flowing water in your vehicle or on foot.
