At 3:29 a.m. on Monday, Oct. 3, the National Weather Service in Honolulu has issued a Flash Flood Watch for the Big Island from 4 a.m. this morning through Tuesday afternoon.

The combination of abundant moisture and an upper-level disturbance could trigger heavy rains and thunderstorms from this morning through Tuesday.

A Flash Flood Watch means that conditions may develop that lead to flash flooding. Flash flooding is very dangerous.

You should monitor later forecasts and be prepared to take action should flash flood warnings be issued.
