0401 PM     Tornado          6 W Estill Springs      35.27N 86.23W
05/25/2025                   Franklin           TN   NWS Storm Survey

            A tornado touched down just east of the
            Bluegill Grill and Marina, producing
            sporadic tree damage between Holiday Drive
            and Awalt Road. The fallen trees missed the
            Bigfoot statue at the Bigfoot RV and Boat
            Storage facility located at the end of Awalt
            Road. At this location, the tornado was
            approximately 100 yards wide, snapping and
            uprooting several hardwood trees. Windspeeds
            at this location were 93 mph, consistent
            with an EF1 tornado. From here, the tornado
            continued skipping to the East/Southeast,
            producing sporadic tree damage along the
            path on Rock Creek Road and again just after
            crossing 41A. Several hardwood and softwood
            trees were snapped and uprooted on Taylor
            Road. Sporadic tree damage continued north
            and east of Estill Springs, with several
            areas of large branches downed along the
            path. The tornado lifted east of Hwy 41A.

0434 PM     Tornado          8 WNW Stevenson         34.91N 85.96W
05/25/2025                   Jackson            AL   NWS Storm Survey

            A survey team from the NWS in Huntsville, AL
            and Jackson County EMA, has determined that
            an EF-0 tornado caused damage in
            northeastern Jackson County. The tornado had
            maximum estimate winds of 85 mph. The
            initial damage was observed in the Cave
            Springs area near County Road 54, where
            large tree branches were downed as the
            tornado tracked east-southeast. Additional
            indicators of tree damage were found near
            the intersection of County Road 53 and
            County Road 147. The tornado then progressed
            along Highway 117 into Stevenson, where
            trees were observed to be uprooted or had
            large branches broken. As the primary damage
            indicators were related to trees, and
            considering the above-average rainfall
            experienced in May, the estimated wind
            speeds were slightly reduced to account for
            highly saturated ground conditions.
