A flash flood watch for Niihau, Kauai and Oahu has been issued, effective from 6 p.m. this evening through Wednesday afternoon.

The National Weather Service said “moist and unstable conditions” will bring the threat of heavy showers and thunderstorms over Kauai tonight, then over Oahu late tonight and early Wednesday. A flash flood watch means that conditions may develop leading to flash flooding, which is very dangerous.

Robert Ballard, the science and operations officer for the National Weather Service in Honolulu, tweeted this morning that vog will not be a problem for most areas today, as Kona winds are pushing the plume away from the isles, with the exception of Hilo. Ballard also said to expect even more muggy weather later today, tonight and Wednesday.
