What the county pages show
- Every tornado since 1950 on a map of the county, colored by strength.
- How many, by month, decade and rating, and the time of day they tend to strike.
- The strongest, deadliest and most recent tornadoes.
- FEMA’s National Risk Index tornado rating and expected annual loss.
Looking up by ZIP code
ZIP codes are matched to counties with the Census Bureau’s 2020 ZIP Code Tabulation Area to county file. A ZIP that crosses county lines shows every county that holds at least a tenth of its land, largest first. ZIP code areas are approximations of mail routes, so check the county name.
