Rating: EF0 Estimated Peak Wind: 80 mph Path Length /statute/: 0.25 miles Path Width /maximum/: 40 yards Fatalities: 0 Injuries: 0 Start Date: 05/17/2024 Start Time: 01:33 PM EDT Start Location: 2 NE Leesville / Carroll County / OH Start Lat/Lon: 40.4655 / -81.1845 End Date: 05/17/2024 End Time: 01:35 PM EDT End Location: 2 NE Leesville / Carroll County / OH End Lat/Lon: 40.4669 / -81.1809 Survey Summary: Video confirmed a brief tornado occurred beginning at the Leesville Lake South Fork Marina and continuing northeast across Leesville Lake. Rapid development was noted as a narrow, intense ground circulation appeared, tossing docks and pontoon boats. Based on the destruction of a tree in tandem with the destruction of non-DIs evident in the video and the visual of rotational speed of the ground circulation, the peak wind in this small tornado is estimated to be EF0 (around 80 mph). .Allegheny County Airport Tornado... Rating: EFU Estimated Peak Wind: Unknown Path Length /statute/: Estimated at 0.6 miles Path Width /maximum/: Unknown Fatalities: 0 Injuries: 0 Start Date: 05/17/2024 Start Time: 02:48 PM EDT Start Location: 1 W West Mifflin / Allegheny County / PA Start Lat/Lon: 40.3588 / -79.9286 End Date: 05/17/2024 End Time: 02:50 PM EDT End Location: West Mifflin / Allegheny County / PA End Lat/Lon: 40.3599 / -79.9171 Survey Summary: Video evidence confirmed a brief, weak tornado tracking just north of the Allegheny County Airport. Video analysis puts the track across the industrial complex located at Noble Drive. No known damage was observed, so wind estimates are unknown. .Elrama/Elizabeth Tornado... Rating: EF0 Estimated Peak Wind: 80 mph Path Length /statute/: 5.9 miles Path Width /maximum/: 75 yards Fatalities: 0 Injuries: 0 Start Date: 05/17/2024 Start Time: 02:54 PM EDT Start Location: 2 SW West Elizabeth / Washington County / PA Start Lat/Lon: 40.2514 / -79.9271 End Date: 05/17/2024 End Time: 03:14 PM EDT End Location: 1 E Lincoln / Allegheny County / PA End Lat/Lon: 40.2924 / -79.83 Survey Summary: Tornadic damage associated with this mesocyclone occurred sporadically from near Elrama to eastern parts of Elizabeth, with several gaps in the damage swath. Damage in Elrama was the most notable along this track, where multiple homes experienced removal of large portions of shingles, with some also losing siding/soffit. Tree damage also was noted in this area. The porch roof of a mobile home was removed and thrown into a neighboring yard in this area, and a swimming pool collapsed as the tornado attempted to lift it. Porch railings and furniture were destroyed and tossed. Home owners reported extreme difficulty attempting to close their front doors as the wind increased rapidly within the tornadic circulation. No homes suffered window loss, suggesting an upper bound on the wind speed. Along the remainder of the path, sporadic tree damage was noted, especially in the area of Boston Hollow Rd and Mansfield Rd. In this segment of the circulation track, the swath of damage was narrow, and characterized by uprooted trees and snapped limbs. Video of this sporadically contracted/intensified circulation was offered, confirming an occasional tornadic ground circulation to supplement the reports of damage. This tornado was rated EF0 with a peak wind speed of 80 mph.NWS Pittsburgh appreciates those who shared their experiences and damage with us to complete our assessment. .Harrison City Tornado... Rating: EF0 Estimated Peak Wind: 70 mph Path Length /statute/: 2.9 miles Path Width /maximum/: 100 yards Fatalities: 0 Injuries: 0 Start Date: 05/17/2024 Start Time: 03:50 PM EDT Start Location: 1 NE Manor / Westmoreland County / PA Start Lat/Lon: 40.3578 / -79.6523 End Date: 05/17/2024 End Time: 04:00 PM EDT End Location: 3 SSE Export / Westmoreland County / PA End Lat/Lon: 40.381 / -79.6054 Survey Summary: Damage was first noted in the vicinity of the Penn Township Municipal Complex, where flag poles were bent, and a tree limb was snapped. The damage swath continued sporadically over the remainder of the track to Greensburg-Jeannette Regional Airport. Although damage throughout was primarily to trees, some impact was observed in a neighborhood along Seslar Drive, where a few homes suffered minor removal of shingles/siding/soffit. At the Regional Airport, a large tree was snapped. Video was provided from multiple sources of persistent low-level rotation that sporadically contracted and tightened the ground circulation to tornadic strength, leading to the appearance of the tornado skipping over areas. The structural damage and some of the tree damage is consistent with peak wind gusts of 70 mph. This tornado will be rated EF0. Thank you to Penn Township and Westmoreland County Emergency Management for their assistance with this survey, and to the impacted public for helping us complete our understanding of the storm's evolution. && EF Scale: The Enhanced Fujita Scale classifies tornadoes into the following categories: EF0.....65 to 85 mph EF1.....86 to 110 mph EF2.....111 to 135 mph EF3.....136 to 165 mph EF4.....166 to 200 mph EF5.....>200 mph NOTE: The information in this statement is preliminary and subject to change pending final review of the events and publication in NWS Storm Data. $$ Kramar/Rackley
