The path drawn at its surveyed width of 440 yards (0.25 mi) — zoom in and the swath grows to true scale. Other tornadoes recorded nearby that day are shown faint.

What EF3 means. On the Enhanced Fujita scale, EF3 is severe damage: whole stories of well-built houses destroyed, large buildings badly damaged, trains overturned, consistent with estimated gusts of 136–165 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-3 tornado touched down near Bull Creek Road, and was on the ground intermittently before lifting near the end of Fulton Road, just short of the Ohio River. The greatest damage occurred about 10 miles east northeast of Charlestown, where a recently constructed two story home was blown off its basement and destroyed. Two large barns, a stable, a silo, and four vehicles were also damaged or destroyed on the same property. Ten other homes were damaged, with four of them receiving severe damage. Five barns and several other outbuildings were destroyed. The tornado left scour marks for nearly one half mile through corn and bean fields between Bull Creek Road and Church Road just after its initial touchdown.

The wider storm

A cold front with strong upper level support collided with a very moist air mass over the lower Ohio Valley. Widespread severe thunderstorms resulted, along with three confirmed tornadoes in south central Indiana. The severe storms and tornadoes produced property damage, widespread areas with downed trees and power lines, and some large hail.

Began near Vesta (38.4716, -85.5539).
