...flash flood watch now in effect through late tonight...

the flash flood watch is now in effect for

* kahoolawe...lanai...maui...molokai...oahu and the big island.

* through tonight

* the combination of deep tropical moisture and an unstable
  airmass will allow for the potential for heavy showers and
  thunderstorms from oahu to the big island.

* heavier downpours and thunderstorms could cause streams to 
  quickly overflow their banks...leading to flash flooding. 

precautionary/preparedness actions...

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. campers and hikers should
consider postponing their outing until the weather is better.
high streams...as well as streams overflowing their banks...could
make conditions very dangerous.
