System May Forecast Tornadoes Weeks Away

Researchers say they've come up with a way to predict the likelihood of tornadoes two or three weeks in advance -- a step toward better warnings of storms that kill an average of 80 Americans each year.

Victor Gensini, a meteorology professor at the College of DuPage outside Chicago, found a link between tornado activity in the United States and complicated atmospheric wave patterns that shift every 40 to 60 days. The pattern is dependable enough that last year he used it to predict overall tornado activity in the nation -- and was right 10 out of 15 times.
