Researchers have highlighted a shift in each the timing and geography of tornadoes, elevating new security issues for communities exterior the standard Twister Alley states. The widening prevalence of twister exercise has some specialists suggesting that the title “Twister Alley” be retired.
The 1,010 tornadoes reported is nearly 40 % greater than the 15-year common of 727 tornadoes for a similar interval. Mississippi leads with 97 twister reviews, adopted by Illinois (93), Missouri (89), and Texas (87), in line with AccuWeather.
