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

The tornado crossed into Hancock County from Daviess County, KY, near Highway 1389. It continued northeast, with intermittent touchdowns, until it lifted in the southwest outskirts of Hawesville. A mobile home was destroyed along Highway 1389. Several barns and sheds were blown down near the intersection of highways 271 and 1389. Most of the damage, however, was in the form of large trees being uprooted or snapped. The parent thunderstorm crossed into Perry County, IN, where it later produced another tornado to the northeast of Cannelton.

The wider storm

A cold front with strong upper level support collided with a very moist air mass over the lower Ohio Valley. The result was a widespread outbreak of severe thunderstorms, and six confirmed tornadoes. The storms produced property damage, downed trees and power lines, and large hail.

Began near Utility (37.8300, -86.8600).
