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

Several trees and large branches were broken where the tornado touched down. Structural damage was found near the intersection of 1st Street and Ab Avenue. This was the most significant damage. A roof was torn off of a 30x30 square foot outbuilding resulting in the failure of two walls. A nearby house received around 20% shingle loss and soffit damage. Numerous large trees were found across 1st Street. Approximately one-half mile east of the intersection of 1st Street and Ab Avenue, about 35% of trees were snapped or uprooted with numerous branches down in a forested area. Several utility wires were also down. Scattered tree and large branches were torn down near where the tornado lifted off of the ground.
