3 E Mount Olive - Locust Fork A NWS Birmingham storm survey team found damage in the Locust Fork area of Blount County consistent with an EF-0 tornado. The tornado potentially formed formed in a heavily wooded area near the Locust Fork River, just west of Standridge Trail. The first observable damage was in the area of Standridge Trail where minor timber damage occurred. Two barns sustained roof damage and one camper trailer was rolled and destroyed. The tornado continued east toward Deaver Walker and Campbell Roads. The circulation was fairly broad. Most damage consisted of sporadic tree fall, either uproots or the occasional snapped trunk. Most locations along Campbell Rd had large branches taken out of trees. A few structures had minor roof damage with at least two structures damaged by tree fall. The tornado moved generally east across Tabernacle Rd and County Rd 13 producing additional sporadic and minor timber damage. The tornado dissipated before crossing Hwy 79 as no observable damage was found downstream of there. Given the weak nature of the circulation, most if not all damage was on the right side with debris facing in a N to NE direction indicating non-divergent damage relative to path. No damage was found on the north side of the damage path. Start: 33.9149/-86.6725 End: 33.9156/-86.6126
