A damage assessment in Rochester has revealed that a tornado did touch down in Rochester on Tuesday. 

The National Weather Service in La Crosse, which covers the Rochester area and southeast Minnesota, determined Thursday afternoon that damage was consistent with what a strong EF-1 tornado can produce. 

The assessment notes that the twister produced maximum wind speeds of 107 mph and was on the ground in southwest Rochester for 1.5 miles, from approximately 5:45 p.m. to 5:52 p.m.

The following damage photos were taken by the NWS damage survey team. 

Olmsted County Emergency Management shared a video of what appears to be a rotating wall cloud moving over Byron, which is located 10 miles west of Rochester. The storm was moving east-southeast, so it's very possible that the rotation over Byron is the same part o the storm that spawned the EF-1 tornado. 

One comment on the video shared a photo of the possible tornado developing in Rochester, and it's quite ominous. 

An EF-1 tornado is the second level of the Enhanced Fujita Scale: 

  • EF-0 produces 65-85 mph winds
  • EF-1 produces 86-110 mph winds
  • EF-2 produces 111-135 mph winds
  • EF-3 produces 136-165 mph winds
  • EF-4 produces 166-200 mph winds
  • EF-5 produces 201+ mph winds
