The path drawn at its surveyed width of 50 yards (0.03 mi) — zoom in and the swath grows to true scale. Other tornadoes recorded nearby that day are shown faint.

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 second tornado touched down approximately 2 miles east-southeast of Ingalls. This tornado was on the ground for about 2 minutes, and traveled approximately 0.3 miles, with estimated peak winds of 100 mph. The tornado inflicted major damaged to a metal barn, removing the roof and exterior walls. Downwind of the barn, 2x4 beams were driven into the ground at different angles. Several trees were damaged, either being snapped or blown over and uprooted.

The wider storm

A potent cyclone crossed northern Illinois, bringing central Indiana into its warm sector. This allowed very strong vertical wind shear courtesy of the system's strong low-level jet stream to combine with the warm sector's adequate instability, producing several severe thunderstorms. Near the greatest shear and instability, small supercell thunderstorms produced severe straight line winds, with one supercell spawning two EF-1 tornadoes in Hancock County.

Began near Eden (39.9423, -85.7692).
