Tornado intensity is measured on two scales (learn more about tornado intensity scales):
| Rating | F Scale (1971-2007) | EF Scale (2007-Present) | Wind Speed Difference |
|---|---|---|---|
| 0 | F0: 40-72 mph | EF0: 65-85 mph | EF0 has higher minimum speed (+25 mph) |
| 1 | F1: 73-112 mph | EF1: 86-110 mph | EF1 has higher minimum (+13 mph), lower maximum (-2 mph) |
| 2 | F2: 113-157 mph | EF2: 111-135 mph | EF2 has lower maximum speed (-22 mph) |
| 3 | F3: 158-206 mph | EF3: 136-165 mph | EF3 has significantly lower speeds (-22 to -41 mph) |
| 4 | F4: 207-260 mph | EF4: 166-200 mph | EF4 has drastically lower speeds (-41 to -60 mph) |
| 5 | F5: 261-318 mph | EF5: >200 mph | EF5 has significantly lower threshold (-61 mph) |
Why the Wind Speed Differences? Research showed the original F-Scale overestimated wind speeds needed to cause specific damage.
Key Improvements in the EF Scale:
For historical consistency, this website groups equivalent ratings together (e.g., both F3 and EF3 tornadoes are considered in the same intensity category despite their significant wind speed differences).
