5 NNW - 6 NNW Eastaboga NWS Birmingham storm survey team assessed timber damage in a relatively localized area on Mudd Street. Timber damage consisted of several uprooted trees, several snapped trunks and several trees having large branches removed from their tops. All debris and tree fall was oriented N to NNE. Although this was a short-lived tornado and short path, overall damage is consistent with a brief EF-0 tornado with max wind of 75 mph. The tornado began near the intersection of Mayfield Rd and Mitchellville Rd then moved northeast toward Mudd St where the most severe damage occurred at two residences. Two homes also sustained minor roof damage. The tornado likely dissipated as it moved into a heavily wooded area as no further damage was observed at downstream road crossings. This event is also associated with evidence of a TDS off of KBMX RADAR, originating directly downstream from the damage location. Start: 33.6806/-86.0640 End: 33.6878/-86.0539
