What EF4 means. On the Enhanced Fujita scale, EF4 is devastating damage: well-built houses levelled, consistent with estimated gusts of 166–200 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.
