Location: FT RECOVERY
Tornado F-scale: EF2
Property damage: 1.00M
Crop damage: 50.00K
Reported by: NWS Storm Survey

The first sign of tornadic damage was observed just east of the Indiana/Ohio state line. Trees were snapped along Park Road, indicative of EF0 tornado damage. The tornado then moved southeast and may have briefly lifted, before touching back down and leaving a noticeable swirl in a wheat field between St Joe Road and Wabash Road. The tornado intensified as it moved across Wabash Road, impacting the Fort Recovery Lumber Yard. Multiple roofs were completely lifted off several outbuildings. Additionally, a collapsed cinder block wall was observed at the Fort Recovery Lumber Yard. This was consistent with EF1 damage.
The tornado then continued moving southeast through wooded areas between Wabash Road and Fort Recovery-Minster Road. Hardwood tree damage was noted in the wooded areas. After crossing Fort Recovery-Minster Road, partial removal of an outbuilding roof was noted along with tree damage. More significant damage then became apparent as the tornado continued southeast impacting the Burrville Road/Hart Road area. Multiple homes along Burrville Road sustained substantial roof damage, including total removal of over half the roof of a single family home. The survey team also noted completely destroyed outbuildings, the removal of attached garages, substantial tree damage, and projectiles embedded within an exterior wall.
Several wood power poles along Burrville Road were also completely broken. Debris from Burrville Road was thrown approximately a half mile toward Wourms Road. In addition, the tornado produced damage along Wourms Road, which included more broken wood power poles. The wooded area along Wourms Road also exhibited the most significant tree damage, where numerous hardwood trees were snapped or knocked over. Damage along Burrville Road and Wourms Road was consistent with low end EF2 damage, with maximum winds of around 115 mph.
The tornado seemed to rapidly weaken as it moved southeast to Fox Road and Meiring Road. The only damage seen was minor damage to an outbuilding and partial removal of the top of a silo. No additional damage was observed to the southeast of this area.

The tornado crossed in front of a farmstead and snapped and uprooted a number of trees in front of the residence. It was at this location where tree damage was estimated to be caused by winds in the 90-95 mph range. The tornado continued southeast to Oxford Road where roofing material was lifted from a home on the north side of the road and a barn on the south side of the road, while also continuing to cause considerable tree damage. The tornado then continued southeast and moved into Butler County about 0.8 miles south southwest of Browns Chapel.
