NORMAN, Okla.—The deadly tornado that struck near Oklahoma City late last week had a record-breaking width of 2.6 miles and was the second top-of-the-scale EF5 twister to hit the area in less than two weeks, the National Weather Service reported Tuesday.

The weather service initially rated the Friday tornado that hit El Reno as an EF3. But the agency upgraded the ranking after surveying damage from the twister, which along with subsequent flooding killed 18 people. The weather service determined that the storm packed winds reaching 295 mph.

At 2.6 miles wide, the tornado peaked at a size of 45 football fields.

“For comparison, this was 30 times larger than our recent tornado in St. Charles-St. Louis and the Metro East,” said News 4 Chief Meteorologist Steve Templeton. “It was also twice as fast as the Metro tornado’s estimated wind speed.”

A mobile radar unit from the University of Oklahoma measured a 295mph wind speed less than 500 feet above the surface.

The update means the Oklahoma City area has seen two of the extremely rare EF5 tornadoes in only 11 days. The other hit Moore, a city about 25 miles away from El Reno, on May 20, killing 24 people and causing widespread damage.

But Friday’s massive tornado avoided the highly populated areas near and around Oklahoma City, and forecasters said that likely saved lives. When the winds were at their most powerful, no structures were nearby, said Rick Smith, chief warning coordination meteorologist for the weather service’s office in Norman.

“Any house would have been completely swept clean on the foundation. That’s just my speculation,” Smith said. “We’re looking at extremes ... in the rare EF5 category. This in the super rare category because we don’t deal with things like this often.”

The EF5 storm that hit Moore decimated neighborhoods. In Friday’s storm, many of the deaths were caused by heavy flash flooding following the storms. Three storm chasers died in that storm.

Smith said the storm—besting a record set in 2004 in Hallam, Neb.—would have made the storm hard to recognize up close.

“A two and a half mile wide tornado would not look like a tornado to a lot of people,” Smith said.
