How Are Tornados Classified?
Tornadoes are categorized by their wind speed and the amount of damage they cause using a scale called the “Enhanced Fujita” scale. It is usually abbreviated as the “EF” scale.
How do you classify a tornado?
Tornadoes are classified into five categories F-0 through F-5. F-0 tornadoes are the mildest. F-5 tornadoes are the most dangerous (and the rarest). F-5 261-318 mph Violent damage homes lifted off foundation and carried considerable distances autos thrown as far as 100 meters.
What are the 5 levels of a tornado?
|Weak||EF0 EF1||Wind speeds of 65 to 110 mph|
|Strong||EF2 EF3||Wind speeds of 111 to 165 mph|
|Violent||EF4 EF5||Wind speeds of 166 to 200 mph or more|
What are most tornadoes classified as?
Most tornadoes are classified as weak with the strongest winds under 100 miles per hour. Within the United States 77% of tornadoes are classified as EF0 and EF1. While these weak tornadoes make up the majority of reported tornadoes they account for a small percentage of the total damages and deaths from tornadoes.
What are the 6 categories of tornadoes?
According to Enhanced Fujita Scale the tornadoes in the United States and Canada can be rated in six categories: EF0 EF1 EF2 EF3 EF4 and EF5.
What is a Category 1 tornado?

Moderate Tornado. Moderate damage: Peels surfaces off roofs mobile homes pushed off foundations or overturned outbuildings demolished moving autos pushed off the roads trees snapped or broken.
Can there be F6 tornadoes?
There is no such thing as an F6 tornado even though Ted Fujita plotted out F6-level winds. The Fujita scale as used for rating tornados only goes up to F5. Even if a tornado had F6-level winds near ground level which is *very* unlikely if not impossible it would only be rated F5.

Is there a scale to measure tornadoes?
The Enhanced Fujita Scale or EF Scale which became operational on February 1 2007 is used to assign a tornado a ‘rating’ based on estimated wind speeds and related damage. … From that a rating (from EF0 to EF5) is assigned.
What is the rarest type of tornado?
What will happen if 2 tornadoes collide?
Usually one storm can capture the other only if it’s much larger and stronger. Otherwise the two storms eventually break free from each other and continue on. Tornadoes also have been seen rotating around each other.

What’s the difference between F5 and EF5?
Differences from the Fujita scale
The old scale lists an F5 tornado as wind speeds of 261–318 mph (420–512 km/h) while the new scale lists an EF5 as a tornado with winds above 200 mph (322 km/h) found to be sufficient to cause the damage previously ascribed to the F5 range of wind speeds.

What is a Level 3 tornado?
EF1 (T2–T3) damage has caused significantly more fatalities than those caused by EF0 tornadoes. At this level damage to mobile homes and other temporary structures becomes significant and cars and other vehicles can be pushed off the road or flipped. Permanent structures can suffer major damage to their roofs.
