* WHAT...Flash flooding caused by excessive rainfall is possible.
* WHERE...Maui, Molokai, Lanai, and Kahoolawe.
* WHEN...Through Saturday afternoon. The greatest risk for flash
flooding is Friday through Saturday.
* IMPACTS...Significant flooding may occur due to the 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...
- Considerable flash flooding is possible as a large and
powerful kona storm northwest of the state draws deep
tropical moisture across the islands. Persistent bands of
heavy rain and thunderstorms may produce intense rainfall
rates, leading to rapid rises in streams and flooding of
roads and low-lying areas.
PRECAUTIONARY/PREPAREDNESS ACTIONS...
You should monitor later forecasts and be prepared to take action
should Flash Flood Warnings be issued.
