Track Summary

This tornado touched down in a wooded area just north of Purvis to Columbia Road, near the intersection of B Young Road. The tornado tracked through an area with fairly young, long leaf pines (10-20ft tall) and managed to uproot/snap several near the trail where the property was accessed. As the tornado crossed the transmission line clearing, several more trees were damaged along with a V based truss tower taken down. Information from the power crew engineers noted that these sort of V truss towers are rated for 100 mph winds. The collapse of this tower, with 100 mph winds, was supported by similar tree damage in and around that location. A TDS from both KLIX/KDGX was noted with a well defined signature. Of note, the presence of the clear TDS seemed to be aided by the tornado traveling through the long leaf pine forest and those extra long needles offering a larger variety of oddly shaped targets for the CC product to indicate.
