An unstable and very moist air mass over the western half of the state will be made even more unstable tonight as a strong upper level disturbance passes over the islands. That could trigger showers, heavy showers and perhaps thunderstorms.

In anticipation, the National Weather Service has issued a Flash Flood Watch for Oahu, Kauai and Niihau - effective from 6 p.m. tonight through 6 p.m. Wednesday.

It is important to note that the exact timing and placement of the heavy showers is uncertain, so residents of all islands should be prepared.

The heavy rain will be widespread and could quickly cause flooding in low-lying areas, on roads and in urban neighborhoods. Intense rainfall rates are possible, especially over slopes and that could cause streams to flood. Remember, it does not have to be raining heavily where you are for flash flooding to occur.
