Sentinel Satellite Data from April 13, 2020 clearly shows a damage scar beginning at the northern tip of Parr Pond in the Savannah River Site and ending near the intersection of Highway 278 and State Road 21. A tornadic debris signature detected by the KCAE radar aligns with the damage scar. A ground survey also indicated a few trees down just off a field on the eastern side of Fellowship Road as tornado dissipated. Based off of high resolution imagery, radar data (including the height debris was detected), and correspondence with a Savannah River Site official, it is estimated that winds reached EF-3 strength, with speeds up to 138 mph.
