Overview

During the early morning hours of July 12th, a line of severe storms tracked from central Minnesota into western Wisconsin.  This line of storms created widespread damaging straight line winds across Anoka and northern Washington Counties in eastern Minnesota, with the damaging winds continuing into northwest St. Croix and southwestern Polk counties in western Wisconsin. Within this broad swath of damaging winds, two concentrated paths of more significant damage was found in the East Bethal, Columbus, Forest Lake area that was determined to be associated with two tornadoes.
