Following up on their successful 2007 season, the Storm Chasers are back with new vehicles, new teams and new tactics. The 2008 tornado season nearly set a record for tornado outbreaks and our determined band of chasers pulled out all the stops to break their own records for intercepts. Sure there were challenges, but with double the number of chase vehicles -- and much more mobility and range -- the Storm Chasers got the job done like never before.

The Storm Chasers are back in 2009 with even more pursuit power. Reed Timmer has jacked up his prime chase vehicle, now christened the Dominator, with armor and new cutting-edge instrumentation. The TIV Crew led by Sean Casey has the next generation Tornado Intercept Vehicle running in top condition with a new camera turret and a lighter, faster chassis. Plus, three new vehicles have been added including Tim Samaras and his Team Twistex, the TIV Doghouse and a new 2009 Jeep for the intrepid SCOUT Team.

So strap yourself into that armchair and join the chase with Storm Chasers, only on the Discovery Channel, Sundays at 10 p.m. ET/PT starting Oct 19.
