Norman —

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.

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.

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.
