This brick and cinder block structure lost its sheet metal roof just before the exterior walls collapsed. Two people took shelter inside the building just before the storm hit and were not injured. The roof of the building was lifted and blown approximately 100 yards. A snapped power pole appeared to be the result of the airborne roof. Trees were also down. The damage pattern was indicative of a strong and narrow microburst. The microburst was estimated to be 20 yards wide and 100 yards long.
