1975 Omaha tornado outbreak
Three people were killed and 133 reported injured. One of the fatalities was thrown by the tornado from her home to a backyard four or five houses away. Debris was found miles away. Over 4,000 buildings were damaged and 287 were destroyed. In terms of damage, it was the costliest tornado in American history to that date, with damages costing at least $250 million to $300 million (around $1.7 billion in 2015 dollars), and insurance costs estimated at up to $1.1 billion (in 1975). It was the third-costliest tornado, behind the Oklahoma City-area F5 tornado on May 3, 1999, and the Wichita Falls, Texas, tornadoes on April 10, 1979, until the Joplin, Missouri EF5 tornado on May 22, 2011. It is now currently the seventh-costliest tornado on record.

Following the tornado the American Red Cross determined that around 139 structures were damaged or destroyed by the storm. With many residents left homeless and the threat of more storms looming, Governor Lee S. Dreyfus declared a state of emergency freeing up the area for aid. The campus of the Moraine Park Technical Institute was severely damaged by the tornado and classes were disrupted.
