Residents are advised to remain cautious around streams and low-lying areas, as conditions may still change following the recent downpours.

Original Post: A flash flood warning has been issued for parts of Hawaiʻi Island due to heavy rainfall, raising the risk of dangerous flooding.

The National Weather Service in Honolulu issued a warning at 4:07 p.m. Monday for the districts of South Kohala, North Kona, and South Kona.

Forecasters say a flash flood warning means flooding is either imminent or already occurring in the affected areas.

Officials warn that flooding conditions can be life-threatening, especially in low-lying or flood-prone locations. Residents are urged to remain alert to rapidly changing conditions and to move to higher ground if necessary.

Motorists are also advised to use caution on roadways due to possible runoff, standing water, debris, and reduced visibility. Authorities warn drivers not to attempt to cross flowing water, whether on foot or in a vehicle.

Road closures may occur without warning as conditions change.

Hawaiʻi County will provide updates as conditions evolve. Residents can receive emergency notifications by signing up for Hawaiʻi County Civil Defense alerts.
