Chasing the world’s biggest tornado

On 31 May 2013, a huge tornado hit an area close to El Reno in the US state of Oklahoma. It was the widest tornado ever recorded and produced extreme winds of more than 400 kilometres an hour. Eight people were killed, including three storm chasers. One of the people tracking the storm was Emily Sutton, a meteorologist with KFOR-TV in Oklahoma City. She’s a member of the station’s storm chasing team and was caught in the tornado. She tells Rob Walker about the impact that day had on her and other storm chasers.
