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, with maximum wind speeds of 130 mph, collapsed 3 metal chicken barns and damaged or destroyed some outbuildings. The tornado continued southeast into NWS WFO Louisville's area of responsibility.

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 Bond (38.6900, -86.3406).
