The 1975 Omaha tornado is a violent tornado that hit the Omaha, Nebraska metropolitan area. It was part of a two-day outbreak that struck the Midwest and Southern United States on May 6–7, 1975, ending in the very early hours of May 8 across Louisiana. South Dakota, Iowa, Texas and Mississippi were also struck by several tornadoes. In total, 36 tornadoes touched down across 6 states. The outbreak killed three people, while injuring hundreds more.

Tornado event

During the early afternoon of May 6, 1975, a tornado watch was issued for much of eastern Nebraska. Initial tornado activity started in northeast Nebraska throughout the first half of the afternoon. At around 4:15 PM, a tornado warning was issued for the Omaha area and an F5 tornado[1] touched down about 15 minutes later in Sarpy County, Nebraska. The storm then moved north-east, cutting into Douglas County crossing Interstate 80 (injuring several motorists) and through west-central sections of the city of Omaha. The tornado chopped a path across 10 miles (16 km) of streets and residences, crossing the city's busiest intersection at 72nd & Dodge before lifting at 4:58 PM.

In one remarkable instance, First United Methodist Church minister of music Mel Olson spotted the rolling clouds in the sky outside the windows of the room where he was rehearsing a children's choir. He led them to safety below the church building. The building, located at 70th and Cass Streets, was struck and heavily damaged by the twister. The room where the children had been practicing, with three walls of windows, was hit and the glass imploded.

Three people were killed and 133 reported injured. One of the fatalities was thrown several feet by the tornado from her home to a backyard four or five houses away.[2] 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 insurance costs estimated at up to $1.1 billion (in 1975 dollars). 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.
