Flash Flood — Valley, Idaho

2010-06-04 · near Mc Call, Valley, Idaho

Event narrative

Browns Pond Dam east of McCall partially failed due to heavy rain, and spilled onto Lick Creek Road, washing out parts of the road.

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.
