What EF1 means. On the Enhanced Fujita scale, EF1 is moderate damage: roofs badly stripped, mobile homes pushed off foundations or overturned, windows broken, consistent with estimated gusts of 86–110 mph. The rating comes from a survey of the worst damage after the storm, not from a wind measurement, so it says as much about what the tornado hit as about how strong it was.

What the National Weather Service wrote

The tornado began just to the south of U.S. Route 22-3 on Roachester Osceola Road, where a large broken tree branch was noted. Additional tree damage was observed along Roachester Osceola Road and on Osceola Road. Large limbs were knocked down and some trees were uprooted. One single family residence also had some loss of roof shingles and gutters on Osceola Road.
