Tornadoes are ranked by the severity of the damage they cause, which is used to estimate wind speed. Each number represents a different level of damage. Here are the categories with wind speed estimates and typical damage.
EF0: 65-85 mph. Shingles and siding peeled from homes, tree limbs broken. Some trees uprooted or snapped.
EF1: 86-110 mph. Roofs of homes badly damaged. Windows broken. Mobile homes overturned or seriously damaged.
EF2: 111-135 mph. Roofs torn from well built houses. Mobile homes completely destroyed. Large trees snapped.
EF3: 136-165 mph: Roofs and multiple walls torn from well built houses. Most weaker structures completely destroyed.
EF4: 166-200 mph: Well built houses completely leveled. Trees debarked. Asphalt peeled from some roads.
EF5: over 200 mph. Very well built houses wiped clean off foundations. Cars tossed upwards of 600 feet (200 meters). Ground surface scoured away in some locations.
