FLOOD WATCH FOR ALL ISLANDS IN THE STATE OF HAWAII...
* WHAT...Flash flooding caused by excessive rainfall is possible.
* WHERE...The island of Kauai, Niihau, Oahu, Maui, Molokai, Lanai,
Kahoolawe, and the Big Island.
* 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.
* ADDITIONAL DETAILS...
- A deep layered trough will develop west of the islands and
draw abundant moisture northward as it strengthens on
Tuesday. Instability and upward forcing will enhance the
available moisture and bring the potential for heavy rain and
thunderstorms leading to flash flooding across all islands in
the state of Hawaii.
