| March 2023 | Tornado (EF1) | Wapakoneta | 7 hurt, $3,000,000 | The first sign of visible damage associated with this tornado occurred on Owl Creek Road. At one residence, two large trees were knocked down while a barn was destroyed at another residence. The tornado strengthened as it moved to the northeast, removing a significant portion of a warehouse building roof and snapping several power poles. Just northeast of here, a large commercial greenhouse was completely leveled. The tornado then crossed the intersection of U.S. 33 and Interstate 75, causing significant roof damage and partial exterior wall collapse to an industrial building. At this point, the tornado was at its strongest with estimated winds of up to 110 mph.||On the east side of Interstate 75 and just north of U.S. 33, a truck stop experienced significant damage and a few semi-trailers were blown over. Just northeast of here, a private campground suffered significant damage. At the campsite, numerous trailers were flipped over and a large meeting hall had its roof removed. Several trees were also knocked down. Seven people were injured when the trailers were flipped at the campground.||As the tornado continued northeast, several farmhouses were damaged and outbuildings were damaged or destroyed between Wapakoneta and Uniopolis, particularly along Middle Pike. Considerable debris was noted in nearby fields. A historic brick school building was also destroyed on Brown Road. Numerous trees were also snapped and uprooted along the path. Sporadic damage to trees and outbuildings continued to the northeast before the tornado apparently lifted near the Auglaize/Allen County line.||This tornado started at 2354 EST, March 31st, 2023 and ended at 0007 EST, April 1st, 2023. The injuries occurred just before midnight EST so were included in the March 2023 Storm Data for Ohio, Southwest. |

| March 2024 | Tornado (EF3) | Fryburg | 2 hurt, $1,000,000 | The tornado began immediately east of Interstate 75, south of Wapakoneta, where it damaged a farm on the west side of Cemetery Road. Video shared on social media showed the tornado rapidly strengthened west of Glacier Hill Lakes RV Resort, causing significant damage to a grove of trees west of the resort. After crossing a field, the tornado moved through the center of the resort, lofting campers and snapping trees. Two individuals at the resort suffered injuries that required hospitalization. The tornado continued eastward toward Wapak-Freyburg Road and caused significant damage to the Resort clubhouse and residential homes on the west side of the road. The collective damage done to the trees and buildings within this corridor of damage justified wind estimates of 140 mph, EF-3. The tornado moved into an open field east of Wapak-Freyburg Road at an unknown intensity. ||Three-tenths of a mile south of Pusheta Road, the tornado caused significant tree damage to three separate groves of trees as it neared Town Line Road. Aerial images provided by the Auglaize County EMA/CERT confirmed the tornado was still strong, at least EF-2 strength, south of Pusheta Road. The tornado likely remained fairly strong as it impacted homes and outbuildings along Town Line Road, Ashburn Road, and Geyer Road. A brief weakening period, or narrowing of the tornado was observed near Geyer, where the tornado remained mainly over open fields. ||The next period of intensification occurred between State Route 65 and Valley Road. Damage to a few homes and outbuildings, along with significant damage to a few groves of trees confirmed this period of intensification. The tornado began to make a more significant southeast turn between Wrestle Creek Road and Valley Road. The strong, likely EF2 tornado continued to move southeastward and entered Logan County at 1843EST, just north of Santa Fe. ||The tornado continued east-southeast across much of Logan County before ending at 1916EST, 3 miles west-southwest of West Mansfield. |

| May 2019 | Tornado (EF1) | Moulton | $500,000 | The tornado appears to have touched down very close to Kettlersville Road, just south of the intersection with County Road 33A. Extensive damage occurred here to a barn, grain silo, trees, and a 19th century residence. The north end of the barn was destroyed and the grain silo was lifted and rolled approximately 150 yards to the northeast. A swirl pattern was evident as well in vegetation along the shore of a pond near where the grain silo fragment came to rest. The back room and associated roof of the 19th century residence was pulled from the main structure, along with the plumbing fixtures and a portion of the concrete sub-floor. The structure and contents of the room and barn were scattered to the northeast along a path approximately 50 yards wide. Several pine trees with trunks approximately 8-10 inches wide were also snapped near the residence. This damage and its dispersal pattern was consistent with 100 to 110 mph winds of an EF1 tornado.||The tornado next crossed County Road 33A between Kettlersville Road and Kohler Lane, damaging power poles along County Road 33A. Two barns and another outbuilding on a property just north of the road were also destroyed. Only small segments of the barns were still standing, suggesting 100 to 110 mph (EF1) winds along this portion of the track. The debris from these structures was scattered over a large area of the adjoining field to the north, northeast and east near the intersection of County Road 33A and Woodland Drive. The tornado likely didn't track directly over this entire area, but instead debris was probably lofted and thrown free of the circulation in many directions, before falling back to the ground nearby.||An absence of damage for approximately 150 yards to the east of the field suggests the tornado briefly lifted, then descended again to strike two more barns and the north side of a house. Both barns lost their roofs and at least half of their exterior walls. Some roof damage also occurred to the house. Debris from these structures was lofted and then dropped to the east in an adjacent field and on both sides of US Route 33.||As the tornado continued east-northeast, it left visible striations in field vegetation and destroyed an outbuilding just west of the County Road 33A overpass across US Route 33. A large portion of the outbuilding was lifted and carried approximately 150 yards to the area just west of the overpass and dropped on the road, where a semi truck crashed into it. The semi driver was injured in the crash. The degree and pattern of damage both here and at the adjacent property to the west are indicative of 100 to 110 mph winds of an EF1 tornado.||No further damage was noted on the north side of US Route 33 or east of the overpass, so dissipation of the tornado likely occurred at this point. |
| May 2019 | Flash Flood | Villa Nova | $500,000 | Numerous roads and homes were flooded in the St Marys and Wapakoneta areas. |
| June 2013 | Tornado (EF0) | Wapakoneta Arpt | $350,000 | The tornado touched down on the north side of State Route 219 east of New Knoxville.

A large amount of sheet metal and tree limbs were deposited on the runway. Further along the path, the tornado damaged six houses and three barns and uprooted trees. One barn was 80 percent destroyed. At the end of the tornado track, a double wide mobile home was picked up and tossed 100 feet to the north on its side. Based on the damage surveyed, the maximum wind speed from this tornado was estimated to be 75 miles per hour. |

Multiple hog barns and a farmstead were destroyed along the path, with winds estimated to be 85 mph at peak intensity. The tornado likely lifted or dissipated around or north of Barber Werner Road and no additional tornado damage was evident to the northeast of here. |
