Location: KUHNTOWN
Tornado F-scale: EF1
Property damage: 50.00K
Crop damage: 0.00K
Reported by: NWS Storm Survey

EF1 tornado confirmed. A tornado touched down on the border of Gilmore and Wayne Townships along Holy Hill Rd. Tree damage was observed with several softwood trees snapped at the trunk. The tornado moved east-southeast and took nearly the entire roof off of a house. It also tore the entire deck off, which was attached with metal straps. A piece of the deck became a projectile and was driven into the windshield of a car. The winds moved a 35 pound battery about 20 yards. The tornado continued down a valley and eventually lifted near Oak Forest Rd. In the valley, numerous hardwood trees were snapped at the trunk, and some of them were uprooted.
