    According to the National Weather Service in Norman, Okla., the tornado, which struck the area near El Reno, Okla., was the widest on record at 2.6 miles.

    The NWS also upgraded the intensity of the storm to EF5, which is the strongest level a tornado can reach on the Enhanced Fujita Scale.

    The tornado was on the ground for 16.2 miles, during May 31, 2013.


    The old record width for a tornado was the F4 Wilber-Hallam, Neb., tornado on May 22, 2004, at 2.5 miles wide.

    The tornado rating scale changed during the 2007 season based on upgraded information from damage caused by storms of F3 and greater intensity.


    The tornado which struck near El Reno was double the width of the storm which hit Moore, Okla., on May 20, 2013.

    This makes the El Reno tornado the second EF5 tornado to strike central Oklahoma in less than two weeks with the prior storm being the Moore tornado.

    There have been 60 EF5/F5 tornadoes in the U.S. since 1950 according to the Storm Prediction Center.
