What the National Weather Service wrote

Numerous roads were flooded or washed out around the McCall area including portions of Highway 55, Warren Wagon Road, Falls Creek Road and Lick Creek Road.

The wider storm

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.

Began near Mc Call (44.9400, -116.0300).
