DES MOINES, Iowa (AP) The National Weather Service says a deadly tornado that leveled half a town in northeast Iowa was the state's strongest twister in 32 years.
The tornado tore through Parkersburg and nearby towns on Sunday, killing seven people and destroying neighborhoods with winds up to 205 mph.
The tornado was the strongest in the United States since May 4, 2007, when a twister flattened Greensburg, Kan., killing 11 people. Both tornadoes were ranked at EF5, the top of the weather service's scale.
Iowa's last EF5 tornado was in June 1976 in the central Iowa town of Jordan. No one was injured.
