The Teachable Moment: Tornado WeekendPosted: April 18, 2011
via NSTA WebNews Digest:
This weekend, nature’s most violent storms hopped across at least six states. Sixty-two tornadoes were recorded inNorth Carolinaalone, killing as many as 24 people—the worst event since 1984. Unusual? No, probably cyclic. In an average year, 800 tornadoes are reported nationwide, resulting in 80 deaths and more than 1,500 injuries. … Most people associate the storms with the nation’s “tornado alley”—a wide swath through the Midwest fromTexasthrough theDakotas. Tornadoes decimate residential areas each year. But this spring’s rash of storms goes above even those norms and seems to have moved farther east.
