It was announced that the damage of an area west of Danbury, WI got hit by a violent downburst. The dimension of that damge was well defined, almost to the foot, and it was long and narrow with no rotational indication, but almost every tree in that area was deolated and snapped off.
The subject building could have been on the edge of the downburst area, but the entire long area for 200 miles SW of there and some to the NE had high winds also and they are looking for signs of tornado damage.
