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.
