Minnesota Sets New Tornado Outbreak Record: 15 On September 20, 2018

The tornado count from last week’s severe storms in southern Minnesota and west-central Wisconsin now stands at 16. Fifteen of those tornadoes were in Minnesota, making the Sept. 20 storms the largest September tornado outbreak on record in the state, according to the National Weather Service. Crews have been surveying the damage across several counties in the wake of the storms in an effort to identify where tornadoes touched down. They also reviewed satellite and radar imagery, spoke with local officials and storm spotters, and used drone and aerial footage. "The difficulty with surveying this event was due in part to many potential tornado tracks amongst widespread wind damage," the Weather Service reported in an update on Friday.
