The tornado which traveled through northern Wisconsin on May 16, 2017, is now the tornado with the longest track of continuous damage in Wisconsin since modern tornado records began in 1950. The tornado's path was 83 miles long. The hardest hit areas were just north of Chetek, Wisconsin, where EF-2 damage was found, and in the Conrath area where EF-3 damage occurred. EF-0 to EF-1 damage occurred along the remainder of the tornado's path. This is the first EF-3 tornado in the state since the Verona tornado in 2014. The EF-Scale is the Enhanced Fujita Scale of tornado damage where an EF-0 is the weakest tornado and an EF-5 is the strongest. See below for the latest information.
