* WHAT...Flash flooding caused by excessive rainfall continues to be
  possible.

* WHERE...All the main Hawaiian islands.

* WHEN...Through late Friday night.

* IMPACTS...Flood prone roads and other low lying areas may be
  closed due to elevated runoff and overflowing streams. Urban areas
  may receive more significant flooding and property damage due to
  rapid runoff. Remember, flash flooding can occur well downstream.

* ADDITIONAL DETAILS...
  - A strong upper level disturbance will bring heavy showers and
    isolated thunderstorms tonight through Friday and Friday
    night. The heaviest downpours will be hit or miss, but where
    they do occur, they will be capable of producing rainfall
    rates in excess of 3 inches per hour.  The threat for flash
    flooding is expected to be the greatest Friday through Friday
    evening. Conditions should steadily improve from west to east
    late Friday into Saturday.


PRECAUTIONARY/PREPAREDNESS ACTIONS...

Remember that it does not have to be raining at your location for
flash flooding to occur. If you notice signs of heavy rain or
thunderstorms upslope, move quickly away from flood prone areas.

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