What the reports say
Written by National Weather Service staff at the time of the event · public domain
Trees and power lines were downed, especially in the southern two thirds of the county. Many large trees were uprooted in and near Vienna. The debris took several days to clean up. About two thirds of the county was without electrical power at one point. A number of houses were damaged by falling trees. Trees completely blocked many roads and highways including U.S. 45 South and Illinois 37 in a number of places. Crews worked well into the night to reopen all streets and highways. The city of Vienna was without power through at least the afternoon of the 9th.
Numerous trees and power lines were down near Cypress. One tree fell on a house. Several miles northwest of Vienna, winds unroofed a double wide mobile home and downed trees, one of which landed on the corner of the mobile home. Four miles northeast of Vienna, numerous large trees were uprooted, and a house received shingle damage. One of the downed trees landed on a house, causing minor damage. A television antenna was toppled, and the latticework was torn off the patio of the house. Several other houses received minor roof damage 6 miles east of Vienna. Downed trees closed short sections of State Routes 37, 146, 147, and about 20 county roads.
Several structures were damaged or destroyed on a farm. One machine shed was levelled, with only the north wall left standing. The roofs were blown off two other sheds. Two grain bins were heavily damaged. One of the bins was blown on its side, and the other bin was shifted three feet off its foundation. Part of the roof to one of the sheds was wrapped around a utility pole. The other part of the roof blew across a road and wrapped around a tractor.
