 Brief Description: EVENT NARRATIVE: A low end EF-2 tornado touched down on Osee Road and was intermittently on the ground approximately 5 miles moving east-southeast, finally lifting between Old Barrett Road and Glade Valley Road. A single wide mobile home was destroyed on Osee Road, causing four injuries. Along the track, cement silos were collapsed, 5 other homes were damaged, and several other structures were heavily damaged. Two people received minor injuries when struck by debris after winds blew out windows in their home. Monetary damages are estimates. EPISODE NARRATIVE: A thunderstorm complex over Kentucky and Tennessee moved east into the area during the evening of May 8th. The storm environment was such that storms would have rotation due to strong wind shear, and a low level boundary in place. Supercells developed over southeast Kentucky and moved southeast into far southwest Virginia and into northwest North Carolina during the late evening of May 8th. One storm produced an EF-2 tornado in Northern Alleghany County, with another brief EF-1 tornado touching down just south of the EF-2 track.
