Violent Tornadoes Hit Ohio Valley

Tornadoes tend to form in late March or April, but they descended early this year in the Ohio Valley and the Southeast U.S. "These were very strong, violent tornadoes," said Greg Carbin, warning-coordinator meteorologist at the Storm Prediction Center in Norman, Oklahoma.

In March, 223 tornadoes were reported in the U.S., compared with a typical number of 80 for that month, according to NOAA. Forty-two people died in an outbreak of at least 75 tornadoes in Alabama, Georgia, Indiana, Ohio, Kentucky and Tennessee. Hardest-hit on March 3 was Henryville, Indiana.
