Oklahoma City tornadoes

A large storm cell, which reportedly produced a multiple vortex tornado, passes south of El Reno, Oklahoma May 31, 2013. The National Weather Service issued a tornado emergency for parts of Oklahoma on Friday, describing weather conditions as "particularly dangerous" a day after more than a dozen reported twisters ripped through the region.
