Ground photo of the worst damaged point, a brick-veneer century house. The roof and some second story walls were destroyed along with the east-facing veranda.
Drone image of the worst damage point. The tornado tore most of the roof and some second story walls off the house. Because the roof was a hip roof design, an upper-bound wind speed of 230 km/h was used as hip roofs are more resistent to being removed than gable roofs.
Drone image of the worst-damaged house along with substantial tree damage on the property, where most trees were snapped or uprooted. In the background is a second property that sustained damage to a house and outbuildings.
Heavily damaged tree line on the worst-damaged property just to the east of the house. Almost all of the trees in this area were snapped or uprooted.
