TornadoRiskCheck asks what your county’s tornado history actually means

Field notes

The site aggregates Storm Prediction Center tornado-track records into county-level categories spanning 1950–2025, with separate counts for weak, significant, violent, and unrated events. Its central distinction is between how often tornadoes occur and whether a county has recorded an EF4–5 event: the page reports 774 such counties. It also places the historical data beside a stated $2,890–$13,280 shelter-cost range and references FEMA and selected state rebate programs.
