Tornados are dangerous and relentless acts of nature that can strike at any time of the year, especially during the warmer seasons.
They can occur in any state in the country, but there are some states that experience more tornadoes than others.
Does Tennessee have tornadoes?
Tennessee does have tornadoes because weather and storm conditions in the state are often ideal for tornado formation.
There are certain areas of Tennessee that are more prone to tornadoes than others. Knowing which Tennessean counties have the most tornadoes is the key to staying alert and safe when traveling.
Tornadoes are even more dangerous in Tennessee due to its dense population, which means the chance of injury or worse during a tornado is more likely than in other states.
The more you learn about tornadoes in Tennessee, the better prepared you will be when making travel or moving plans.
Is Tennessee Part of Tornado Alley?
Tennessee is not a part of Tornado Alley, despite the fact that many tornadoes spawn there every year.
Some weather professionals also include Illinois, Indiana, Minnesota, and parts of Ohio in the mix. It is also important to know that several researchers believe that there is more than one Tornado Alley.
Many even refer to parts of the Tennessee Valley being in what they call Dixie Alley.
Each of these Tornado Alleys in various parts of the country lies where warm air meets cooler, dry air, which just happens to be the perfect recipe for tornadoes.
What Part of Tennessee Has the Least Tornadoes?
The eastern part of Tennessee has the least number of tornadoes each year. From the years 1950 to 2020, the eastern part of Tennessee recorded only 243 tornados.
In contrast, during the same span of years, western Tennessee had 381 tornados.
The central part of Tennessee recorded 638 tornados, more than double what occurred in eastern Tennessee during the same timeframe.
Where Do Most Tornadoes Occur in Tennessee?
The central portion of Tennessee has the most tornadoes in the state. This region produces a noticeably larger number of tornados annually in Tennessee than any other region.
Wilson County comes in second with a total of 54 and in third, Davidson County had 53 tornadoes during the same timeframe.
It may be surprising to know that Shelby County is not located in the central portion of Tennessee and instead sits on the southwestern corner of the state.
Shelby County does sit closer to Tornado Alley, which explains the high number of tornadoes it sees each year.
Which Counties Have the Least Tornadoes in Tennessee?
While there are many counties in Tennessee that see a lot of tornadoes, there are several that rarely have any.
From 1950 to 2021, Campbell County had the least number of tornadoes in Tennessee with 1 during that entire time.
Unicoi, Union, and Hancock County all tie for second with only 2 tornadoes each during the same span of years. If you are looking for the most likely tornado-free areas in Tennessee, these counties are the answer.
