US Tornado Map — Every Significant Tornado Since 1950
Interactive map of tornado paths rated EF3 and stronger, from the NOAA Storm Prediction Center database. Hover any path for details. Filter by year, EF rating, and fatalities.
About This Map
This map displays every tornado in the NOAA Storm Prediction Center database rated EF3 or stronger since 1950. Each line represents the tornado's official path from the NWS post-event damage survey — straight-line from the touchdown latitude/longitude to the dissipation latitude/longitude. Tornadoes with an unknown end point (about 5% of the dataset, mostly pre-1990s) are shown as single-point markers at the touchdown location. The data loaded here is capped at 6,000 most recent qualifying events for performance; use the filters to narrow.
About multi-state tornadoes: 211 of the 3,277 strong tornadoes in this set crossed state lines, with another 6 crossing three. These appear with only the touchdown state in the label (e.g. a line starting in Oklahoma and ending in Arkansas is labeled “OK + 1 state”). The longest such paths are genuine — the 1925 Tri-State Tornado tracked 219 miles from Missouri through Illinois to Indiana. This reflects actual tornado behavior, not a data error.
Pre-2007 tornadoes were rated on the original Fujita (F) scale; 2007 and later use the Enhanced Fujita (EF) scale. Ratings of F5 and EF5 are treated as equivalent for statistical and mapping purposes.
