What EF2 means. On the Enhanced Fujita scale, EF2 is considerable damage: roofs torn off well-built houses, mobile homes destroyed, large trees snapped or uprooted, consistent with estimated gusts of 111–135 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

This strong and long-tracked EF-2 tornado began about 5 miles east of Waukon and continued east-southeast causing a continuous path of tree damage all the way to the Misssissippi River near Lock and Dam 9. The tornado also damaged farm outbuildings and a few residences. Extensive tree damage along Waterville Road formed the basis for the EF-2 rating for this tornado. The tornado crossed the Mississippi River and continued east into Wisconsin.
