Flash Flood — Washington, Idaho

2010-06-04 · near Cambridge, Washington, Idaho

Event narrative

Washington County Emergency Manager reported Rush Creek was flooding on roads just east of Cambridge and flooding on Advent Gulch Road northwest of Cambridge.

Wider weather episode

A deep low pressure system anchored in the Gulf of Alaska and a zonal flow pattern across the Pacific Northwest and Intermountain West provided the right ingredients for a sustained moisture plume which produced convection and periods of moderate to heavy rain over a three day period causing flooding and flash flooding, and severe thunderstorms across Southeast Oregon and Southwest Idaho.
