Tornadoes by decade in Wyoming
All tornado reports against only the strong ones (F2 and above). Averages are per year over the years the federal record covers completely — 1952, 1976 and 1993 are each missing whole months in NOAA’s own files and are left out.
| Decade | All reports | Strong (F2+) | All per year | Strong per year |
|---|---|---|---|---|
| 1950s | 38 | 11 | 4 | 1 |
| 1960s | 73 | 15 | 7 | 2 |
| 1970s | 112 | 11 | 12 | 1 |
| 1980s | 111 | 11 | 11 | 1 |
| 1990s | 146 | 1 | 16 | 0 |
| 2000s | 84 | 5 | 8 | 0 |
| 2010s | 119 | 14 | 12 | 1 |
The 2020s are left out because the decade is not finished. Reports are counted per county, so one tornado crossing a county line can appear more than once.
