On what date did the 2013 El Reno tornado occur? It occurred on May 31, 2013.

The tornado formed at about 6:03 p.m. Central Daylight Time in Canadian County, west-southwest of El Reno, Oklahoma, and dissipated roughly 40 minutes later. It was part of the major tornado outbreak that affected the Great Plains from May 26 through May 31, 2013.

The storm became famous for its unusual size and structure. It was a rain-wrapped, multiple-vortex tornado that reached a maximum width of about 2.6 miles, making it the widest tornado then recorded. Mobile radar also detected extreme winds inside smaller subvortices, although the official damage-based rating remained EF3.

A common mix-up is confusing this event with the deadly 2011 El Reno–Piedmont tornado or the May 20, 2013 Moore tornado. The 2013 El Reno tornado struck on May 31 and killed eight people, including four storm chasers, while injuring 151 others.
