Days with a Violent Tornado, 1950–2025

About this chart

Each dot is one day with a violent tornado, placed by its year across and its date up the calendar, January at the bottom and December at the top. F5 dots are ringed, and the counts above the chart run as the years are drawn. A short tick marks a year with none. The animation draws the years in over thirty-eight seconds, holds on the latest year for two seconds, and loops. The scrubber pauses on any year, and the dots shown can be limited to the ringed ones and the speed changed in the controls.

Method

Each dot is one day on which at least one violent tornado — one rated F4, F5, EF4 or EF5 — touched down in the United States, from the Storm Prediction Center's severe weather database. The dot's year is the year of that day and its height in the calendar is the date. Behind the 415 days are 656 violent tornadoes: most of those days had one, and 3 April 1974 had thirty. A day is ringed where at least one of its tornadoes was rated F5 or EF5. Ratings are assigned by damage survey after the event and the practice has changed over the period, so the count of violent tornadoes is not a like-for-like measure across the whole span; the database also holds two to three hundred tornadoes a year in recent years with no rating at all, almost all of them weak, and an unrated tornado is not counted here. The calendar is a fixed 365-day year, with 29 February in 1 March's place. The years run from the first year of the database to the last complete year; a year with none is marked with a short tick. The counts of days and of days with an F5 are computed from the rows the page serves.

Data table

Every day on which at least one violent tornado touched down in the United States, one row per day: the number of violent tornadoes that day, how many of them were rated F5 or EF5, the deaths those tornadoes caused and the states they crossed, from the Storm Prediction Center's severe weather database, 1950 to 2025. Retrieved 18 September 2026. These are the 415 rows the chart draws; the day of year is on a fixed 365-day calendar, 29 February counted as 1 March, a violent tornado is one rated F4 or above, and the deaths are those from the violent tornadoes alone, not from every tornado that day.
