A diagram of the Fujita scale as it relates to the Beaufort scale and the Mach number scale. For many years, before the advent of Doppler radar, scientists relied on educated guesses for tornado wind speed. The only evidence indicating wind speeds found in the tornado was the damage left behind by tornadoes that struck populated areas.
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.

The new scale more accurately matches wind speeds to the severity of damage caused by the tornado. [8] Though each damage level is associated with a wind speed, the Fujita scale is effectively a damage scale, and the wind speeds associated with the damage listed are not rigorously verified.
The original scale is named after Dr. Ted Fujita, who developed the system to help provide a wind estimate for the amount and type of damage that a tornado can produce. In 2007, the Enhanced ...
The high-wind event occurred around 1 a.m. Tuesday and split trees in homeowners’ yards along Sams Point Road, damaging one car and a garage roof, according to reporting from The Post and Courier.
The International Fujita scale (abbreviated as IF-Scale) rates the intensity of tornadoes and other wind events based on the severity of the damage they cause. [1] It is used by the European Severe Storms Laboratory (ESSL) and various other organizations including Deutscher Wetterdienst (DWD) and State Meteorological Agency (AEMET) .
The Enhanced Fujita scale measures a tornado's intensity on a scale of 1 to 5 based on its wind speed estimates and resulting damages.
