Officials expect that the killer tornado that leveled parts of Moore, Oklahoma, last week will turn out to be the most destructive in American history, but none of that damage, it appears, will be to the storm-chasing business.

Hundreds of amateur storm chasers live near central Oklahoma and dozens do it professionally, hopping in their cars to rush toward tornadoes as others head for shelters. They compete against each other to squire around tourists during tornado season and to get storm videos that they post on their websites.

Chris McBee, who runs a severe weather tourism company called Rapid Rotation Tours, was expecting a British tourist for a week in their bid to get close to tornadoes. Nobody has canceled.
