Published 12:12 pm Thursday, May 6, 2021

Over the last decade tornado patterns have shifted, moving out of “Tornado Alley” in the midwest and into the southeastern United States.

“Kansas, Texas and South Dakota have seen significantly fewer tornadoes, meanwhile, Southern states like Louisiana, Kentucky and Mississippi have seen their number of tornadoes increase by 70% or more,” said Nick VinZant, Sr. Research Analyst at QuoteWizard.

An analysis of the tornadic activity in Mississippi shows that the state has had 377 more tornadoes over the last decade, that’s a 74.8% increase over 2000-2009.

The state-by-state reports find that the overall number of tornadoes in the country has increased 11.7% from 2010 to 2019.

While states like Mississippi, Louisiana and Kentucky have seen dramatic increases, South Dakota, Florida and South Carolina have the largest decrease in tornadic activity in those years.

Nationwide, tornadoes have caused more than $14.1 billion in damages.
