The path drawn at its surveyed width of 150 yards (0.09 mi) — zoom in and the swath grows to true scale. Other tornadoes recorded nearby that day are shown faint.

What EF0 means. On the Enhanced Fujita scale, EF0 is light damage: shingles and siding peeled, gutters torn, branches broken, consistent with estimated gusts of 65–85 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-0 tornado with maximum winds of 75 mph was discovered in northeast Shelby County to the north of Morristown. Numerous trees were snapped along and just east of the Big Blue River and Asbury Road from near County Road 1100 North to the Shelby-Hancock County line. Two homes sustained minor damage, and a gentleman sustained injuries from a tree falling on his automobile.

The wider storm

The approach of a strong low pressure system from the west set the stage for a significant severe weather outbreak across central Indiana on May 25th. Eight tornadoes touched down in central Indiana, with an additional one moving into the area from southern Indiana. In addition, widespread wind damage and large hail impacted the area. Straight line winds to over 70 mph impacted the area as well, knocking down trees, power lines, as well as damaging structures and blowing over trucks. Straight line wind damage was noted near the tornado paths as well. Hail into the 3 to 4 inch range fell from some of the storms, causing damage. The large hail stones were also blown into structures by the strong straight line winds, causing additional damage.

Began near Morristown (39.6909, -85.7041).
