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.

northeast before dissipating just east of 900 E and just south of 100 S. Numerous

several homes were destroyed. Tornado weakened as it crossed I-69 yet continued to

produce varying degrees of damage to barns, trees and homes before it dissipated.
