The Fujita Scale, also known as the Fujita-Pearson Scale rates the intensity of the tornado. This scale measures both the path length and the path width. The categories on this scale go from what is known as an F0 to F5. The following shows the damage that you could expect depending on the category the storm is rated:
• F0 – An F0 storm has winds of 42 – 72 miles per hour and is considered a light storm. The typical damage from this type of storm would be shallow rooted trees pushed over, tree branches broken, chimney damage, and damage to signs.
• F1 – An F1 storm has winds of 73 – 112 miles per hour and is considered a moderate storm. The typical damage from an F1 storm would be roof damage, windows broken, garages damaged, mobile homes turned over, and possibly tree trunks being snapped.
• F2 – An F2 storm has winds of 113 – 157 miles per hour and is considered a significant storm. The typical damage you might see from an F2 storm would be roofs torn off of houses, mobile homes demolished, large trees uprooted, and debris turned into missiles.
• F3 – An F3 storm has winds of 158 – 206 miles per hour and is considered a severe storm. The typical damage you might see at your home would be trees uprooted, roof and walls torn from your home.
• F4 – An F4 storm has winds of 207 – 260 miles per hour and is considered an extreme storm. The typical damage you might see is homes being leveled, cars thrown, and debris being turned into missiles.
• F5 – An F5 storm has winds of 261 – 318 miles per hour and is considered a catastrophic storm. The typical damage you might see is a home being lifted from its foundations and carried through the air, trees being totally debarked, and automobiles being tossed through the air.
