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.
