.OVERVIEW...a powerful thunderstorm tracked across northwest
Wisconsin during the early evening of 5/16/2017. The storm
produced a strong, long tracked tornado that first developed over
southeastern Polk County, in the vicinity of Clear Lake, then
tracked mostly eastward across southern Barron and southern Rusk
counties, possibly into southern Price county. The hardest hit
area was just north of Chetek, WI where EF2+ damage was found. The
rest of the path ranged from EF0 to EF1 with mainly tree damage,
and mostly minor structural damage.

Due to such a long possible path length of greater than 60 miles,
we are awaiting additional information, possibly in the form of
areal survey results before finalizing the width and length. It
is possible more than one tornado occurred if a break in the path
is found. In that case, the length would be shorter than 60
