May 15, 1968:

An F5 tornado moved through Butler, Chickasaw, Floyd, Franklin, and Howard Counties in northeast Iowa. The tornado moved northeast from north of Hansell, passing east of Aredale and Marble Rock, before devastating Charles City. The tornado grew larger and more intense as it approached Charles City. The huge funnel passed directly through town, destroying 337 homes, and causing about $30 million in damage. The tornado continued to the northeast hitting Elma and it caused another $1.5 million in damages. From there the tornado turned to the north and dissipated south of Chester, 4 miles south of the Minnesota border. Nearly 2000 homes were damaged or destroyed. All 13 deaths occurred in Floyd County. 450 injuries were reported in Floyd County and 12 injuries in Howard County. Another F5 tornado moved north-northeast from southwest of Oelwein to Maynard and east of Randalia in Fayette County, IA. Homes were leveled and swept away in both Oelwein and Maynard. The warning sirens sounded for only 15 seconds before power failed in Oelwein. Nearly 1000 homes were damaged or destroyed along the path, and 34 people had to be hospitalized. Almost 1,000 families were affected. In addition to these F5 tornadoes, an F2 tornado touched down 6 miles south of Cresco, IA and two weak F1 tornadoes touched down in Dodge County, MN.
