Tornado season is right around the corner. And storm chasers are getting ready to spend their lives on the road hoping a combination of forecasting and gut instinct will lead them close to a twister -- and invaluable research data, epic photos and video.

Journalist Brantley Hargrove recently wrote a book about Coloradan Tim Samaras, "The Man Who Caught The Storm." Hargrove tells Colorado Matters about Samaras’s work, and his his eventual death in 2013 alongside his son Paul and long time chasing partner Carl Young in the El Reno, Oklahoma, tornado.
