Event narrative

Law Enforcement reported several small rock slides on highway 31 near Metaline Falls, WA between milepost 10 and 15.

Wider weather episode

A four day interval in which a series of warm weather systems with very well maintained moisture feeds from the subtropics slowly moved through Northeast Washington. These systems brought considerable rainfall to the mountains and valleys and caused much of the mid-slope elevation snow to melt. The resulting runoff caused some streams and rivers to flood in addition to some debris flows, mudslides, and minor street flooding.
