Cincinnati, Ohio
In the early evening hours of Saturday, August 9, the tornado formed in the Cincinnati suburb of Wyoming, 8 mi north-northeast of Downtown Cincinnati. Moving east–southeast at 40 –, it traveled through the city's suburban neighborhoods of Hartwell and Roselawn, and the several of its northeastern suburbs, including Reading, Arlington Heights, Golf Manor, and Madeira. It carved a path through Hamilton and Clermont Counties that was 22 mi long and up to 400 yd wide. It hit the communities of Milford and Perintown before finally dissipating north of Williamsburg.

All the deaths were in Hamilton County, including three members of one family. In Madeira, 30 people were injured when a tent they were in at a church event collapsed on top of them. The most severe damage, all of the deaths, and the majority of injuries, occurred in the area between Hartwell and Golf Manor.

Despite it being among the most significant killer tornadoes in the Cincinnati area, it is considered by some to be one of "Cincinnati's Forgotten Tornadoes" due to several other events in the U.S. in August 1969, including the Manson murders (which occurred early that morning) and Hurricane Camille. In addition, the area was hit by eight significant tornadoes in 1974, 1990, 1999 and 2012, including two tornadoes rated F4 and F5 in 1974 and another one rated F4 in 1999.
