| March 2024 | Tornado (EF3) | Farmland | 1 killed, 37 hurt, $25,000,000 | The Selma tornado lifted in the open area and fields between|eastern Delaware county to near Farmland before redeveloping. As it|moved through Rural Randolph county it bent or snapped numerous|utility poles along State Road 32. Also, a large blade on one of|the wind turbines in the area was badly damaged.||As the tornado entered Winchester, it severely damaged many homes|and snapped and uprooted trees in a west-to-east path through|Winchester. There was clear evidence of the tornado`s rotational|circulation, with uprooted trees pointed to the east on the|immediate south side of the tornado, and to the northwest on the|immediate north side of the tornado. The damage pattern also|indicated the possibility of small multiple vortices rotating|around the main vortex. In the residential core of the town, the|maximum intensity of the tornado was estimated around 130 mph or|high-end EF2 strength.||The greatest damage in Winchester occurred on the east side of|town at the Taco Bell, as the anchored building was destroyed, as|was a church immediately east of the restaurant. In this|concentrated area, the NWS Team estimated maximum winds of 155-165|mph, or high- end EF3 damage. Maximum path width in Winchester|was estimated at up to 0.4 mile or 700 yards.||Farther east across more rural eastern Randolph County, a few|structures had significant damage, debris was blown in fields,|many trees were snapped, and a silo was damaged, all indicative of|EF2 maximum damage in the 115-125 mph range.||The tornado continued to the Indiana-Ohio state line, with less|intense damage primarily to trees before crossing into Ohio. |
