WHAT
Flash flooding caused by excessive rainfall is possible for windward and southeast Big Island.
WHERE
The Big Island.
WHEN
From midnight HST tonight through Monday afternoon.
IMPACTS
Flood prone roads and other low lying areas may be closed due to elevated runoff and overflowing streams. Urban areas may receive more significant flooding and property damage due to rapid runoff.
ADDITIONAL DETAILS
- Tropical Storm Moke is forecast to bring periods of heavy rain to the Big Island from late tonight through Monday afternoon. Rainfall totals of 5 to 10 inches, locally up to 15 inches, are possible over the windward and southeast slopes of the Big Island. It will not take a significant amount of rain to cause flash flooding due to saturated grounds from recent heavy rain.
