	A team from the National Weather Service office in Wilmington conducted a 
	survey of damage and has confirmed an EF-1 tornado in southern Ross County. 
	Damage was consistent with a rating on the high end of the EF1 category. The 
	tornado initially touched down near a grocery store near State Route 772 and 
	Valley Road in Summithill, where several trees were knocked down and 
	uprooted. There were several intermittent touch downs between Summithill and 
	Denver. To the southeast of Summithill, along Schaffer Road, approximately 
	6 homes and 2 mobile homes were damaged and numerous trees were snapped and 
	uprooted. An eye-witness on Schaffer Road reported a rope tornado which had 
	several brief touch downs. Further southeast in the Denver area, a home 
	received substantial damage with a loss of the roof and some walls down. 
	Portions of the roof were thrown 700 yards and wrapped around trees. There 
	was also widespread crop damage in the area. Two barns off of Denver Road 
	were completely destroyed, and uprooted trees were observed intermittently 
	along this path. The damage path was intermittent and the length was 
	estimated to be 3.06 miles. The maximum path width was estimated to be one 
	quarter of a mile.
