Track of the May 20, 2013 Norman, OK EF-5 tornado


The May 20, 2013 twister in Moore, Okla., struck a devastating blow to a region hit by five tornadoes in 15 years, including the strongest tornado ever recorded.

The 2013 Moore tornado was a violent tornado that occurred on the afternoon of May 20, 2013. The EF5 tornado with winds estimated at 210 miles per hour (340 km/h) impacted Moore, Oklahoma, and adjacent areas, killing at least 24 people, including 9 children, and injuring more than 240 others. In a news conference on May 21, the governor said there were 237 confirmed injuries. The tornado was part of a larger weather system that had produced several other tornadoes over the previous two days. The tornado touched down at 2:45 p.m. CDT (19:45 UTC) west of Newcastle, staying on the ground for approximately 50 minutes over a 17-mile (27 km) path, crossing through a heavily populated section of Moore. The tornado was 1.3 miles (2.1 km) wide at its peak. YouTube Video

The record-breaking May 3, 1999, tornado — an EF-5 (the strength rating on the Enhanced Fujita scale) — also traced a path through Moore. Like a pair of deadly snakes, the tracks of the twister and the massive 1999 tornado twine across central Oklahoma, even crossing paths.
