* Flash Flood Watch to include Kahoolawe, Kauai, Lanai, Molokai,
Niihau and Oahu.
* From 6 PM HST this evening through Monday afternoon.
* Abundant low level moisture over the eastern half of the state
will spread to the entire island chain tonight and Sunday. A
strong upper level trough approaching the state will produce
unstable conditions that will generate heavy showers and
* Due to increasing instability, heavy showers and thunderstorms
could develop rapidly. Heavy rainfall could affect urban and
leeward areas, which are more susceptible to flooding problems.

to flash flooding. Flash flooding is a dangerous situation.
Please monitor forecasts and be prepared to take action should
Flash Flood Warnings be issued.
