| Brief Description: An F2 tornado passed southeast through southern Fayette County PA, the northeast tip of Preston County WV, and into northwest Garrett County MD. The total length of the tornado as it passed across these three counties was 12 miles. Damage included a completely destroyed dairy barn, two completely destroyed house trailers, and at least 21 other structures heavily damaged, many with roofs partially or completely peeled off. Several cows were killed, with one cow thrown through the air over 100 yards. A clearly visible 300-yard wide, 1-mile long swath of trees which were completely sheared/uprooted was present near the Pennsylvania/West Virginia state border. One Fayette County official estimated at least two million dollars damage in lost timber alone in that county. Despite the damage, interviews with law enforcement officials, paramedics and local residents revealed no injuries occurred. | |||||||||||
