2 ESE Millport - 3 ESE Millport National Weather Service meteorologists surveyed minor damage in Far Southern Lamar County and determined that it was consistent with a low end EF-1 tornado. The tornado touched down in a wooded area about 150 yards west of Leonard Drive, over a grassy plot, and then uprooted and snapped a dozen pine trees across a utility right of way. The worst damage, which tipped the rating into the low end, EF-1 range, occurred where the tornado first began. The tornado then continued east-southeastward across Leonard Drive, producing minor sporadic tree damage for the remainder of the path, which crossed Evans Road/SLS Road, just south of South Lamar High School. Sporadic tree damage continued to just across Conklan Road, where several large limbs and tree tops were twisted but still intact. The tornado damage path was 1.0 mile long and was 115 yards wide at its widest point. Start: 33.5583/-88.0453 End: 33.5552/-88.0281

NWS EF Scale: F1

Episode Narrative

A line of strong thunderstorms moved through northwest Alabama during the early morning hours of Tuesday, November 6th, 2018. Strong wind shear was already in place, with a northward moving instability axis that aided in storm intensification and more robust rotation. One of these storms moved into southern Lamar County from Mississippi. After some interaction between the storm's couplet and a southeastward moving wind shift, the couplet intensified as it moved into the Millport area and produced a weak tornado.
