The tornado started 4.5 miles west of Little Sioux, Iowa in Burt County, NE where center pivot irrigation systems were tipped over and numerous trees were damaged. The storm tracked northeast across the Missouri River and interstate 29 near mile marker 97, where a semi-truck flipped on its side. Heading northeast, the tornado snapped power poles and then entered the Little Sioux Scout Ranch. The tornado destroyed the ranger's home near the entrance of the park and was rated a solid EF-3. The storm then blew down trees and struck a bunk house where the four fatalities occurred. The storm continued northeast into Preparation Canyon State Park and continued to topple trees. Prior to entering the park, a farmstead sustained damage. The tornado then hit another farmstead approximately 2.5 miles southwest of Moorhead, IA. Trees were blown down and sheds were damaged on the farmstead. The tornado then began to weaken and lifted 2 miles southwest of Moorhead, IA. In addition to the fatalities, the tornado also resulted in 48 confirmed injuries.
