List of tornado outbreaks by Outbreak Intensity Score

In late 2023, American meteorologist and tornado expert Thomas P. Grazulis created the Outbreak Intensity Score as a way to rank tornado outbreaks. For the score, only significant tornadoes are counted: F2/EF2 tornadoes receive 2 points each, F3/EF3 tornadoes receive 5 points each, F4/EF4 tornadoes receive 10 points each, and F5/EF5 tornadoes receive 15 points each. The number of total points determine the rating for the outbreak, which is broken up into seven categories.

Type of outbreak	Weak	Minor	Significant	Major	Devastating	Historic	Super
Number of points	2–6	7–10	11–29	30–79	80–119	120–249	250+
