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

Damage from this tornado is believed to have begun near the intersection of Schnorf-Jones Road and Stocker Road in Darke County, just over a mile southeast of Pitsburg.

The tornado crossed into Miami County at 2128EST along Hall Road, about 4 miles east of Pitsburg. The tornado continued to move east across Miami County, eventually ending at 2144EST, about 4 miles southwest of Troy. While the tornado produced low-end EF3 damage in Miami County, the maximum strength in Darke County was consistent with EF1 damage and the maximum tornado width was about 1200 yards.
