- Reporting changed over time. Tornado counts rose from the 1990s on as Doppler radar, spotter networks and cameras caught more weak tornadoes. Counts from different decades are not directly comparable, especially for the weakest ratings.
- F and EF ratings. The Enhanced Fujita (EF) Scale replaced the Fujita (F) Scale on 02/01/07. Both estimate wind speed from damage, but they use different damage indicators, so each rating is shown with its own scale.
- Ratings before the mid 1970s. The F Scale came into use in the early 1970s. Tornadoes from 1950 until then were rated afterward from newspaper accounts, photos and records, which tends to make those ratings less certain.
