| July 2022 | Tornado (EF0) | Hayesville | 3 hurt, $250,000 | The first damage occurred on three separate properties on the west side of Kingston Pike where an RV was flipped on its side and a neighboring house had roof damage. |One injury was reported within the RV. Another property received minor structural damage. The tornado continued east-northeast and caused tree and minor structural damage to properties along Gay-Dreisbach Road and Ludwig-Dresback Road. The maximum width of the tornado was likely on Ludwig-Dresback Road due to the tree damage observed. Beyond this damage, accessibility became more challenging and the distance between damage points increased. The tornado may have lifted several times throughout the remainder of the track as the tornado became less organized.||It is unknown if any damage occurred between Morris Salem Road and State Route 56 East. On the north side of State Route 56 East, a single property received minor tree and structure damage with the worst damage associated with a new outbuilding that collapsed. Two more injuries were reported within this structure. After crossing more agricultural fields, damage was observed at the Logan Elm School property on Tarlton Road. Several buildings received minor damage along with damage to various portions of the sports complex. Security camera footage helped confirm that a circulation was still evident at this location.||The tornado moved northeast across Tarlton Road and weakened as it continued into Fairfield County, ending at 1522EST, about 2.2 miles south of Stoutsville. |

| May 2019 | Tornado (EF1) | Stringtown | $1,500,000 | The beginning of the tornado-related damage was observed on State Route 56, just west of the Salt Creek Elementary School. A property along this stretch of road sustained extensive roof damage in which nearly the entire roof was removed from the structure. Significant debris scatter of lumber and insulation was observed on this property and surrounding properties. Splatter was observed on the southward-facing facade of the structure, with several pieces of lumber forced into the ground of the yard.||At a nearby structure on Kime-Holderman Road, just south of State Route 56, minor siding damage was observed on the north-facing side of the home. Part of the roof of this house was also removed. Extensive tree damage was also observed near the intersection of Kime-Holderman Road and State Route 56. Another home on State Route 56, just west of Salt Creek Elementary School, had minor roof damage.||A bit further east, approximately across the street from Salt Creek Elementary School, a home being constructed had several walls removed from the structure. Additionally, a barn on a property nearby sustained some roof damage, but the nearby home appeared to have little to no visible damage. | |Slightly farther east on State Route 56 and about two tenths of a mile south of South Perry Road, an outbuilding was completely destroyed and the home on the property sustained partial roof removal and wall damage/failure. Several large trees were also downed in this vicinity. The damage observed on this property, between State Route 56 and Tarlton-Adelphi Road, was some of the most significant associated with this tornado and was likely the result of winds in excess of 100 mph.||Along the western side of Tarlton-Adelphi Road, extensive tree damage and some minor structural damage was observed on several properties. Extensive debris was strewn across the nearby fields just east of these structures. However, a review of locations further east showed little to no signs of visible damage from the public access points and therefore it was determined that the tornado likely lifted here. |
| May 2019 | Tornado (EF1) | Hayesville | $1,000,000 | The tornado is believed to have first touched down just west of Circleville-Kingston Road, along which there was a structure that sustained some minor roof damage close to the intersection with Gay-Dreisbach Road. ||A bit further to the east, at the next north-south oriented road (Gay-Dreisbach Road), several structures sustained more significant damage. In particular, a house had its garage destroyed, with the roof removed completely and placed in the yard. Some structural damage also occurred to the connecting wall to the main house. It was at this location where some of the most severe damage associated with this tornado was observed to have occurred. Damage at this property along Gay-Dreisbach Road was consistent with estimated winds of around 100 mph.||An additional area of damage believed to be tornadic in nature was near the intersection of Ludwig-Dresback Road and Morris Salem Road, where several large trees were downed and minor roof damage was observed at a property on Ludwig-Dresback Road. A barn was also damaged on the same property. Further southeast, sporadic, but locally extensive, tree damage and minor structural (siding/roof) damage was observed at several properties on Zane Trail Road near Morris Salem Road.||Just south of the intersection of Morris Salem and Zane Trail Roads, extensive tree damage was observed at multiple properties on Morris Salem Road. An outdoor structure at a residence was completely destroyed with the garage of the home also dismantled. A corner of a home at the same property was also severely damaged, with a portion of the wall partially removed, leaving a gaping hole in the corner of the structure. Debris from the structures and tree damage were strewn in the nearby fields. ||Further east and southeast, sporadic tree and minor structural damage was observed at several locations just east of Morris Salem Road. However, damage was not observed much further to the south or east, and therefore it is believed the tornado lifted just east of Morris Salem Road, south of Zane Trail Road. Damage in these areas was consistent with an EF0 tornado, particularly at the properties near the intersection of Morris Salem Road and Zane Trail Road. |

Siding was also removed from this property and numerous hardwood trees were snapped or knocked down. Roof and siding damage was also observed on the property on the other side of Wolfe Road. Maximum winds along Wolfe Road were likely upward of 110 mph.||The tornado likely weakened further east as it crossed Boggs Road, but roof from a metal shed on Boggs Road was noted in a nearby field.

Minor damage continued through the neighborhood before the tornado crossed Darby Creek Road, damaging a single property. On this property, the garage roof was lifted off the structure and landed on the other side of Darby Creek Road. ||The tornado likely crossed Big Darby Creek, however, damage could not be verified due to the lack of accessible roads. ||The next area of damage was observed toward the town of Orient, where multiple abandoned structures were damaged at the Pickaway Correctional Institution south of town. This damage was verified through video shared on social media. Most of the structures had large amounts of roof panel loss which was scattered across a nearby field. ||The only signs of the tornado in the town of Orient was scattered building insulation found in trees. It is believed that the tornado likely dissipated as it entered Orient. |
| July 2021 | Tornado (EF0) | New Holland | $100,000 | Based on aerial footage and photos, the tornado appeared to have initially touched down in a field just northwest of Dick Road.

Aerial footage confirmed evidence of the tornado in the grass and field between Dick Road and Mouser Road. Debris from the outbuilding was also scattered throughout the field between Dick Road and Mouser Road. Additional damage occurred on a property on Mouser Road, where two barns were completely destroyed. The tornado is believed to have then lifted shortly after it destroyed the barns. While the tornado ended before reaching U.S. 22, debris from the destroyed Mouser Road barns was thrown about one quarter of a mile and was noted on the other side of U.S. 22.||Based on the evaluation of the damage, winds associated with this brief tornado were around 85 mph. |
