Tornado - Near Lapel Hamilton and Madison Counties Date 07/29/2024 Time (Local) 9:41 PM - 9:50 PM EDT EF Rating EF-2 Est. Peak Winds 130 mph Path Length 3.04 miles Max Width 50 yards Injuries/Deaths 0/0 Summary: The tornado began as an EF-0 with damage to the roof of a metal barn and uprooted trees along Strawtown Rd, just west of State Road 13 in Hamilton County. The tornado skipped over SR 13 before quickly landing in a field at a cemetery south of Perkinsville in Madison County, causing sporadic tree damage. The tornado crossed the White River, snapping and uprooting several trees at a residence south of County Road 300 North where it was rated an EF-1. The tornado then moved into a corn field before lifting briefly prior to hitting the Frankton Lapel Administration Building where significant brick wall and roof damage occurred. The roof of a small gymnasium at this building was lifted and thrown approximately 150 yards to the north northeast while the western brick wall collapsed inward. Numerous concrete masonry blocks were thrown from the wall into the top of several school buses that also sustained damage. One bus had a small but long metal support driven through the frame. The tornado was rated EF-2 here before it continued into a corn field to the northeast and dissipated. Track Map
