Severe Storm, Supercell, and Tornado Trends

The document reports a significant increase in billion-dollar severe storms in the U.S., with a shift in tornado activity toward the Southeast and Mid-South. It highlights the vulnerability of mobile home residents and projects a nationwide increase in supercell frequency and a shift toward more winter and early spring storms by the end of the century.

• Severe storms have become more frequent and costly in the U.S., accounting for 48% of all billion-dollar weather disasters since 1980. Between 2001 and 2022, the U.S. experienced 142 billion-dollar severe storms, which is nearly six times the 25 events recorded from 1980 to 2000. The average annual cost of these events rose from $2.5 billion (1980–2000) to $15.4 billion (2001•2022).
• Tornado activity is shifting eastward into the Southeast and Mid-South, including states such as Mississippi, Alabama, Arkansas, Tennessee, Kentucky, Missouri, Illinois, and Indiana. This shift increases risk for residents of mobile homes, which are concentrated in these regions and are 15 to 20 times more likely to result in a tornado-related fatality than permanent homes.
