Numerous trees were blown down and large branches snapped. The winds also damaged several mobile homes, sheds, and roofs. The damage was most concentated in a two mile wide path in the north half of the county from the Gasconade River to Swiss. At the intersection of Old Iron Road and Highway 19, strong winds ripped part of the roof off a house. A school building at the east end of County Road NN also lost part of its roof.
