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

An EF-1 tornado touched down near the Newton County and McDonald County line southeast of Seneca. The tornado lifted near Highway DD and Eagle Drive. There was roof damage to several homes and outbuilding. Estimated maximum winds were up to 90 mph.
