Dixie Alley is a region of the southern United States prone to severe thunderstorms and tornadoes, especially in spring and late fall. The term was coined in 1971 by Allen Pearson, then director of the National Severe Storms Forecast Center, after an outbreak across the Mississippi Delta [1]. Based on data since 1985, Alabama averages 42 tornadoes a year, and its annual average death toll of 41 is the highest in the nation.
| Average tornadoes | 42 a year (since 1985) |
|---|---|
| Average deaths | 41 a year, highest in the nation |
| Weak (EF-0/EF-1) | 71 percent since 1950 |
| Strong or violent (EF-4/EF-5) | About 2 percent |
| Busiest month | April (575 tornadoes, 1950-2022) |
| April 27, 2011 | 62 tornadoes in 24 hours |
Why Alabama is different
Alabama tornadoes often form in high-precipitation supercells, where rain wraps around the tornado and hides it. Many occur at night, and hills and trees block the view, making them harder to see than on the Great Plains [1].
Seasons
The core months are March, April and May plus November and December. A chart for 1950-2022 shows April with the most tornadoes (575), followed by March (400) and November (292). Summer tornadoes are usually tied to tropical storms or hurricanes [1]. See Climate of Alabama.
Major outbreaks
On March 21, 1932, the “Enigma Tornado Outbreak” killed at least 300 people statewide, including 58 in Chilton County. On May 27, 1973, an EF-4 tornado traveled 139.1 miles, the longest recorded track in Alabama. During the April 3-4, 1974 Super Outbreak, up to 86 people died in Guin, Marion County, when an EF-5 tornado struck [1].
April 2011
April 2011 saw 107 tornadoes, the most ever recorded in Alabama in one month. On April 27, 62 tornadoes struck in 24 hours, a world record, and the outbreak killed 252 people in Alabama, according to this EOA article. The wider April 25-28 event produced 362 tornadoes in 21 states, including an EF-5 that hit Hackleburg and Phil Campbell with estimated winds of 210 mph, and an EF-4 at Tuscaloosa that killed more than 65 people. Another EOA article gives 238 deaths for April 27, so figures differ by source [1].
Warnings and safety
The Storm Prediction Center in Norman, Oklahoma, issues watches, and warnings come when tornadoes are detected or reported. Lead times range from seconds to more than 30 minutes. The article recommends at least two ways to receive warnings, preferably a NOAA Weather Radio and a warning-sharing smartphone app, and says outdoor sirens should not be the primary alert [1].
