During the afternoon of June 1, 2018, a storm dropped four tornadoes around Gillette, WY.

Based on video evidence, a brief tornado touched down about 11 miles west of Gillette. It was located between Montgomery Road and Echeta Road, south of the Oriva Hills subdivision. It was on the ground for about four minutes, from around 1:34 pm MDT until 1:38 pm MDT. Since there was no visible damage, this tornado was rated as EF-0.

It traveled in an east northeast direction and dissipated around 1:52 pm MDT. It was on the ground for around 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. The majority of damage associated with the tornado was consistent with an EF-1 and EF-2 tornado, but the most severe damage was consistent with an EF-3 tornado. Therefore, this tornado has been rated EF-3, with winds estimated around 136 mph.

The third tornado was a short-lived landspout. It developed 3 miles north northeast of Gillette, in the Warrior Hills Subdivision. It was on the ground for one half mile, from around 1:55 pm MDT until 1:56 pm MDT. It damaged a large shed, flipped a camper onto a vehicle, destroyed another camper, and damaged several wooden fences. This tornado has been rated as EF-1, with winds estimated around 90 mph.

The fourth tornado touched down over the west pit of the Eagle Butte Mine at 1:59 pm MDT, about 7 miles north of Gillette.
