Twisters are twirling away from Tornado Alley.
From 1979 to 2017, annual tornado frequency slightly decreased over the region, which stretches across the central and southern Great Plains of the United States, a study finds. Conversely, a higher number of storms touched down in areas east of the Mississippi River over the same period, researchers report October 17 in npj Climate and Atmospheric Science.
"The great Tornado Alley is still No. 1 in terms of [overall] frequency," says coauthor Victor Gensini, an applied climatologist at Northern Illinois University in DeKalb. But more tornadoes in communities ill-prepared to face the relatively unfamiliar storms, such as in the southeastern United States, could mean more infrastructure damage and loss of life.
The Deep South should get to work on its tornado shelters?

The Mississippi delta maybe but most of the South has hills sufficient to make tornadoes not too much of an issue.
My rights don't end where your fear begins.

Florida - Hills? I don't think so.
Overreacting is one thing, sticking your head up your ass hoping the problem goes away is another - edIII

The tornadoes that ripped through northwest Georgia / northeast Alabama ~5-10 years back didn't seem to care too much about the hills they shaved clean.

Hills neither help nor hinder tornadoes. Tornadoes don't usually jump over valleys (the set of complex conditions that support tornadoes can vary), but rather roll down them and up the other side. And hills don't stop tornadoes from forming, though elevation can matter under some circumstances (such as those places on earth that are close to, or above, the storm system altitude).

I'm in very hilly southern Indiana. In the early 70s a F5 started in kentucky, rolled down the several hundred foot drop into the ohio river, crossed it, went up the other side and kept going. We have tornadoes here constantly (at least a dozen a year within 30mi of me). They aren't uncommon at all in hilly areas.
