The National Weather Service has upgraded the El Reno, Oklahoma Tornado from Friday Evening May 31st to an EF-5, making it the second tornado to reach this strength in the past 2 weeks.
The El Reno Tornado was said to be 2.6 miles wide, which would make this the widest tornado ever documented.
According to The National Weather Service, this upgrade was based on information from a Doppler On Wheels that measured low level winds in this storm of 296 miles per hour.
At this size, the El Reno Tornado would be double the width of the May 20th tornado that devastated the town of Moore, Oklahoma.
Until now, the largest tornado on record was an F-4 Tornado from May 22nd, 2004 in Wilber-Hallam, Nebraska, and had a width of 2.5 miles.
This tornado is also responsible for the deaths of three storm chasers during this severe weather event.
