What EF0 means. On the Enhanced Fujita scale, EF0 is light damage: shingles and siding peeled, gutters torn, branches broken, consistent with estimated gusts of 65–85 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

A brief tornado with estimated peak winds of 80 mph touched down near 169th Street and Crawford Avenue. The tornado produced tree damage along its path, which brought down power lines. A large pine tree was uprooted on Briargate Drive, which fell onto a house. The tornado ended just after this location, just south of 167th Street.
