* WHAT...Flash flooding caused by excessive rainfall is possible.
* WHERE...Maui, Molokai, Lanai, and Kahoolawe.
* WHEN...From Wednesday morning through Saturday afternoon.
* 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 beginning early
Wednesday as a large and powerful kona storm develops
northwest of the state and 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.

A powerful kona storm will impact the western end of the state tonight, then spread across the remainder of the smaller islands by midweek and the Big Island towards the end of the week. While flash flooding remains a major concern (see the Flood Watch for additional details), confidence is increasing that strong to severe thunderstorms may develop Wednesday into the weekend. Damaging winds will likely be the primary hazard with these storms, though large hail cannot be ruled out. In addition to the heavy rainfall and severe thunderstorm threat, strong and potentially damaging kona winds are possible late in the week and into the weekend. $$
