EF1 tornado in Kane County, Illinois

This tornado touched down along Keslinger Road west of Randall Road in Geneva. The first instance of damage was noted to a metal garage/storage building, which had portions of roofing and walls damaged or removed and was shifted off its foundation. The structure did not appear to be properly anchored to its foundation. Trees and a traffic light were then damaged as the tornado crossed the intersection, with shingle, soffit, and siding damage noted at a commercial building before the tornado moved into a residential area. A concentrated corridor of damage consistent with EF-1 wind speeds near 95 mph occurred along Cambridge Drive and Essex Court, where damage to several roofs and windows was observed. In addition, nearby trees were significantly damaged with almost all large branches snapped. The tornado weakened and narrowed as it moved east just north of Kaneville Road, with tree damage noted until the tornado dissipated near Kaneville Road and Burgess Road. The tornado was on the ground for fewer than two minutes.
