Tornado funnels continued through the state where they heavily damaged two manufacturing plants --Vermeer in Pella and Lenox in Marshalltown.
Seven people at Vermeer were injured and 10 people were being treated at a Marshalltown hospital for injuries.
No deaths were reported as a result of the tornadoes.
Marshalltown experienced overturned and missing vehicles, damaged buildings, and downed trees and utility lines, Omaha's WOWT reported.
City Administrator Jessica Kinser said Marshalltown officials declared a state of emergency.
"Everyone is advised to stay away from downtown Marshalltown until further notice," Kinser said. "We also ask that people stay off cell lines unless necessary, to allow for emergency phone traffic."
