An Idaho weatherman says Japan's Yakuza mafia used a Russian-made electromagnetic generator to cause Hurricane Katrina in a bid to avenge itself for the Hiroshima atom bomb attack. Meteorologist Scott Stevens, a nine-year veteran of KPVI-TV in Pocatello, said he was struggling to forecast weather patterns starting in 1998 when he discovered the theory on the Internet. It's now detailed on Stevens' website, www.weatherwars.info. Stevens...says a little-known oversight in physical laws makes it possible to create and control storms -- especially if you're armed with the Cold War-era weapon said to have been made by the Russians in 1976. Stevens' bosses at KPVI-TV say their employee can think and say what he wants as long as he keeps the station out of the debate and acknowledges that his views are his own opinion. Bill Fouch, KPVI's general manager, said. "He's very knowledgeable about weather, and he's very popular."
