EF0 Weak 65-85 mph |
EF1 Moderate 86-110 mph |
EF2 Significant 111-135 mph |
EF3 Severe 136-165 mph |

When a tornado is known to have occurred but does not cause damage to any qualified damage indicators, or if the only damage is located in an area that is inaccessible to NWS storm survey personnel, then a tornado may be assigned the EF-Unknown (EF-U) rating.
