* WHAT...Flash flooding caused by excessive rainfall is possible.
* WHERE...All Hawaiian islands.
* WHEN...From Wednesday morning through Friday afternoon.
* IMPACTS...Significant flooding may occur due to excessive rainfall
and overflow of streams and drainages. Roads in several areas may
be closed, along with property damage in urban or low lying spots
due to runoff. Landslides may also occur in areas with steep
terrain.

- Low pressure will develop west of the islands and draw

thunderstorms leading to flash flooding over all Hawaiian
islands.
