What does the F mean in tornado ratings?
The Fujita (F) Scale was originally developed by Dr. Tetsuya Theodore Fujita to estimate tornado wind speeds based on damage left behind by a tornado. An Enhanced Fujita (EF) Scale, developed by a forum of nationally renowned meteorologists and wind engineers, makes improvements to the original F scale.
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.
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.
Is an F12 tornado possible?
An F12 tornado would have winds of about 740 MPH, the speed of sound. Roughly 3/4 of all tornadoes are EF0 or EF1 tornadoes and have winds that are less than 100 MPH. EF4 and EF5 tornadoes are rare but cause the majority of tornado deaths….
