Tornado Ranking System ^hot^ (2024)

The United States and Canada use the (EF Scale) to rate tornado intensity. It is based on the damage caused by the tornado, not solely by measured wind speed.

Understanding the Tornado Ranking System: From Fujita to Enhanced Fujita tornado ranking system

Fujita’s system ranked tornadoes from based on the damage they caused to homes and trees. However, the original scale had a major flaw: it overestimated wind speeds. For an F5 tornado, the scale suggested winds over 300 mph, which engineers later determined was likely higher than necessary to cause total destruction. The Modern Standard: The Enhanced Fujita Scale (EF-Scale) The United States and Canada use the (EF
