Map of Tornado locations
An interagency damage assessment has determined that at least three distinct tornadoes occurred in an area of west central Minnesota from central Clay County, across Wilkin County, and into southwest Otter Tail County.  The outbreak occurred mainly between 12:30 and 2:30 pm CDT on Saturday, 21 April 2012.  During this time there were numerous reports of funnels but only a few produced damaging touchdowns.


Our thanks are extended to the Clay, Wilkin, and Otter Tail County Emergency Management Directors for their assistance in verifying the initial reports of damage, checking for any additional damage, and gathering the damage photos for this summary.
