YouTube user Charles Cook uploaded a video clip that captured the birth of the devastating May 20, 2013 tornado at Newcastle, Oklahoma. That tornado later moved to Moore, where it turned into an EF5 tornado, with peak winds at 210 mph (340 km/h) and width of 1.3 miles (2.1 km).
"The birth of the May 20, 2013 tornado," Cook wrote. "Moved from there to Moore where it turned into an F4. God be with its victims."
"Incredible video my Dad took of the May 20th tornado FORMING and destroying everything in its path near Newcastle," the user wrote. "He was out that way for work today and just happened to be in the right place at the right time. He was worried it was going to come back at him and was searching for a way to scoot out [of its] way once he was able to gauge how insanely close it was to him. He hung in there, though. Unbelievable."
