The 2025 tornado season in the United States is the most active in over a decade, with more preliminary tornado reports by May 20 than in any year since 2011. Fueled by a series of major outbreaks this spring, four states have emerged as the hardest hit so far this year.
Over 900 tornadoes in 2025, 280 above normal
As of May 20, the Storm Prediction Center (SPC) has logged 922 preliminary filtered tornado reports nationwide- 281 more than the historical average of 641. That puts 2025 well ahead of every tornado season in the past decade at this point in the year, including last year.
Four states stand out with unusually high tornado reports. Mississippi leads with 97 tornado reports this year. Illinois follows with 93 reports. Missouri comes in third with 89, and Texas rounds out the top four with 87 tornado reports.
The ranking of the top four states has not changed since the end of April.
