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.

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.
