Official Bulletin

A trough moving over the state from the southwest will bring
abundant tropical moisture late Tuesday through at least Wednesday
night. Heavy rain and isolated thunderstorms are expected to produce
flash flooding, and while the greatest flood threat will be focused
over Oahu and Maui County, all islands are at risk.

* WHAT...Flash flooding caused by excessive rainfall continues to be
possible.

* WHERE...All main Hawaiian Islands.

* WHEN...From Tuesday morning through late Wednesday night.

* 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...
- Heavy showers and isolated thunderstorms with intense rain rates
are expected to develop on Tuesday and continue through Wednesday
night as a trough moves over the state. While the greatest flood
threat will be focused over Oahu and Maui County, all islands are
at risk.

You should monitor later forecasts and be prepared to take action
should Flash Flood Warnings be issued.
