On July 19 and 20, 2018, an unexpected strong tornado outbreak affected Iowa and nearby areas. The event was triggered mostly by three supercells that produced several tornadoes across southeastern Iowa east and southeast of Des Moines. Two of the tornadoes reached EF3 intensity, affecting Pella and Marshalltown. These were the strongest tornadoes to hit Iowa since June 22, 2015, when another EF3 tornado struck near Lovilia. Of the 37 injuries, 13 occurred in Pella, and 23 in Marshalltown, and one the following day in Indiana. The event was also notable due to the Table Rock Lake duck boat accident that killed 17 people and injured 7 others at Table Rock Lake, Missouri.
