Most of the damage was to trees. Several tress in the narrow path were damaged between Garfield and Victoria. In general, young trees with a diameter of under 1ft were uprooted, larger trees, diameter greater than 1.5ft, appeared snapped off about halfway up. The snapped off tree tops appear to have caused a significant portion of the roof damage in the area. It appeared that only two or three houses sustained roof damage directly tied to the tornado. The uprooted/snapped off trees gave us the best indication of convergence . . . One lady found a large computer screen in her backyard and doesn't know who it belongs to. A trampoline was found in a factory parking lot, 3 houses down from where it originally was located. One family is missing a plastic 8FtX4Ft (rough size estimate) dining table from their back deck. Due to the sheds being moved, we think this is an F1 (low range) tornado.
