HONOLULU (HawaiiNewsNow) - The flash flood watch is now in effect for all Hawaiian Islands through Friday afternoon.
Low pressure west of the state will continue moving slowly west-southwest. The atmosphere over Hawaii will remain unstable enough for the possibility of heavy showers and thunderstorms overnight and Friday.
A flash flood watch means that conditions may develop that lead to flash flooding. Prepare now for the possibility of very heavy rainfall that could cause flash flooding.
