ON THIS DATE IN 1884: The 1884 Enigma outbreak is thought to be among the largest and most widespread tornado outbreaks in American history, striking on February 19–20, 1884.
As the precise number of tornadoes as well as fatalities incurred during the outbreak are unknown, the nickname “Enigma outbreak” has come to be associated with the storm. Nonetheless, an inspection of newspaper reports and governmental studies published in the aftermath reveals tornadoes (or more likely — long-track tornado families) striking Alabama, Georgia, Illinois, Indiana, Kentucky, Mississippi, North Carolina, South Carolina, Tennessee and Virginia, with an estimation of at least 50 tornadoes.
In Alabama these tornadoes affected at least eight separate counties across the state from around midday until late evening, resulting in at least 39 fatalities and 116 injuries.
