The 2035 Cicero, Indiana tornado was a violent EF5 tornado that struck central Indiana, primarily the city of Cicero, in the afternoon of Monday, July 16, 2035. The tornado was on the ground for 26 minutes over an 11.95-mile path, and killed six people and injured 27, all within the Cicero city limits. The tornado was the first to be rated F5 or EF5 in the month of July since the 1996 Oakfield, Wisconsin tornado, as well as the first F5 or EF5 tornado in the state of Indiana since April 3, 1974, and the first violent tornado in Indiana since March 2, 2012.
Despite the relatively low loss of life, the tornado was one of the costliest in United States history, causing catastrophic damage to a football stadium, an Indiana Water Systems depot, a water treatment plant, and a marina, as well as hundreds of houses, leaving a total of $400 million in damage. While damage in Cicero received significant media coverage in the days following the tornado, the tornado faded into obscurity in the following years, having occurred between the extremely prolific June 2034 tornado outbreak sequence and the catastrophic 2037 Super Outbreak.
The intensity of the tornado was described in local media as being "unprecedented" in Indiana state history; however, many meteorologists disputed the unofficial label, considering the 1974 Sayler Park, Ohio tornado to have been likely stronger than the Cicero tornado, although no F5 damage occurred within Indiana in the 1974 tornado. Officially, the Cicero tornado was rated as a "marginal EF5", with winds estimated at 205 miles per hour. The tornado's rating was disputed by meteorologists, as many of the houses that were swept away in Cicero were not particularly well-built; however, the EF5 rating stood based on damage to the marina, water treatment plant, and football stadium, as well as vehicle damage and ground scouring.
