* WHAT...Flash flooding caused by excessive rainfall is possible.

* WHERE...All the main Hawaiian islands.

* WHEN...Through 6 AM Saturday.

* 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 scattered 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.
