Parent article: List of tornadoes and tornado outbreaks

This is a dynamic list and may never be able to satisfy particular standards for completeness. You can help by adding missing items with reliable sources.


These are some notable tornadoes, tornado outbreaks, and tornado outbreak sequences that have occurred in North America.

  1. The listing is U.S.-centric, with more and more consistent information available for U.S. tornadoes. Some North American outbreaks affecting the U.S. may only have U.S. tornado information.
  2. Exact death and injury counts are not possible, especially for large events and events before 1955.
  3. Prior to 1950 in the United States, only significant tornadoes are listed for the number of tornadoes in outbreaks.
  4. Due to increasing detection, particularly in the U.S., numbers of counted tornadoes have increased markedly in recent decades although number of actual tornadoes and counted significant tornadoes has not. In older events, the number of tornadoes officially counted is likely underestimated.
