A survey also found straight-line damage across "a much wider area. This area of damage extended about 13 miles in length, stretching from far southeastern Clermont County through north central Brown County."
Tornado damage started near Lucas Road about a mile northeast of Hamersville, according to the National Service Service office in Wilmington:
More significant damage was observed near the intersection of White Oak Valley Road and Smokey Row Road, where a well-built home suffered partial roof loss and additional loss of roofing material. At another property on White Oak Valley Road, a trailer was flipped over. Tree damage was extensive along Smokey Row Road, especially near its intersection with Vinegar Hill Road.
On New Hope-McKinley Road, about a half mile east of US-68, a mobile home had its roof completely removed. Debris from this roof was observed thrown about 500 yards downstream (northeast) of its origin. Additional tree damage was observed along New Hope-White Oak Station Road.
In Clermont County, the tornado that struck west of Felicity had a maximum width of 200 yards and was on the ground for about 3.5 miles.
