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.

What the National Weather Service wrote

This tornado touched down about ten miles west-northwest of downtown Gillette. It was on the ground for about 11 minutes over the Oriva Hills subdivision. The tornado destroyed and damaged numerous homes and outbuildings, rolled vehicles, and snapped electrical transmission poles and trees. Top wind speeds were estimated at 136 mph, so the tornado was rated as an EF-3.

The wider storm

A supercell thunderstorm tracked east-northeast across central Campbell County. As the storm approached Gillette, it produced multiple tornadoes. A storm survey, along with photos and video, determined that four tornadoes occurred just west and north of Gillette. The largest tornado was on the ground for about ten minutes and briefly reached EF-3 strength as it tracked about ten miles west-northwest of Gillette. There were two injuries, with significant damage to numerous buildings and homes along its path.
