The upgrade was based on information from OU RaxPol Doppler data or mobile radar data, that measured low level winds of 296 miles per hour.

The National Weather Service said some of the subvortices had a forward movement of up to 180 miles per hour.

This tornado is double the width of the May 20 tornado in Moore, Oklahoma.

The F-4 Wilber-Hallam, Nebraska, tornado May 22, 2004 was the previous record holder for the widest tornado on record at 2.5 miles wide.
