When tornadoes hit Jefferson County
March has brought the most, 6 of 27. About 44% touched down between 12 pm and 6 pm (Central Standard Time, as the Storm Prediction Center records it). Winter tornadoes (December to February) make up 30% of the total, a sign of the cool-season storms common in the South.
By decade
More tornadoes in recent decades mostly reflects better detection and reporting (Doppler radar, storm spotters, damage surveys), especially for weak EF0 tornadoes, not necessarily more storms. The 2020s bar covers only 2020 to 2024.
How strong they were
| Rating | Estimated 3-second gust | Tornadoes |
|---|---|---|
| F0 / EF0 | Light damage: 65 to 85 mph (EF scale) | 4 |
| F1 / EF1 | Moderate: 86 to 110 mph | 16 |
| F2 / EF2 | Considerable: 111 to 135 mph | 4 |
| F3 / EF3 | Severe: 136 to 165 mph | 2 |
| F4 / EF4 | Devastating: 166 to 200 mph | 1 |
| F5 / EF5 | Incredible: over 200 mph | 0 |
Tornadoes before February 2007 were rated on the original Fujita (F) scale; since then the National Weather Service uses the Enhanced Fujita (EF) scale. Wind speeds above are EF-scale estimates from damage, not measurements. See what the EF scale means.

FEMA’s tornado risk rating
FEMA’s National Risk Index rates the tornado risk in Jefferson County as relatively low, with a score of 36 out of 100 compared with every other U.S. county. It estimates about 0.54 tornadoes a year here and an expected annual loss of about $450,799 to buildings, people and farming. The index mixes how often tornadoes strike with what is exposed and how well a community can recover, so a busy rural county can rate lower than a less active city.

Staying safe
When a tornado warning is issued, act at once. Go to a basement, storm shelter or safe room. With none, use a small windowless room on the lowest floor, as far from outside walls as you can, and cover your head and neck. Mobile homes and cars are not safe places to ride out a tornado: leave early for a sturdy building or shelter. Read the full tornado safety guide and the National Weather Service advice linked below.
