The path drawn at its surveyed width of 30 yards (0.02 mi) — zoom in and the swath grows to true scale. Other tornadoes recorded nearby that day are shown faint.

What EF2 means. On the Enhanced Fujita scale, EF2 is considerable damage: roofs torn off well-built houses, mobile homes destroyed, large trees snapped or uprooted, consistent with estimated gusts of 111–135 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

This EF-2 tornado was on the ground intermittently throughout the 1.52 mile path. The maximum wind associated with this tornado was approximately 125 mph. Early on, a swath of trees were snapped at elevated heights. Later, two very large trees were snapped and a metal power line truss collapsed.

The wider storm

A low pressure system brought very warm and unstable air for late February and early March to central Indiana. The result was severe thunderstorms and 7 tornadoes from the 28th of February to March 1st. A surface frontal system interacted with an unstable and high shear environment to produce the severe weather.

Began near Black Oak (38.6573, -87.0782).
