- 1913 – A tornado outbreak resulted in at least 76 deaths across much of the Southern United States. A mile-wide F4 tornado destroyed farms across Floyd and Gordon counties, Georgia, killing 15 people. Another F4 tornado killed 10 people near Middleton and Henderson, Tennessee.
- 1990 – A tornado outbreak affected parts of the Great Plains and Midwestern United States. A single supercell in Kansas produced two F5 tornadoes in succession, which killed one person each. The first caused major damage in Hesston while the second swept away farms near Goessel, producing "extreme F5" damage. Amateur video captured the dissipating Hesston tornado and newly-formed Goessel tornado as they merged, the first time such an event had been filmed.
