Hawaii Independent Staff

HONOLULU—A Flash Flood Watch is now in effect for Kauai, Niihau, Kahoolawe, Lanai, Maui, Molokai, Hawaii Island, and Oahu through late Wednesday night.

Moist and unstable atmospheric conditions associated with an upper level trough will maintain the possibility of heavy rainfall and a slight chance of thunderstorms.

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

Monitor later forecasts and be prepared to take action should Flash Flood Warnings be issued.
