Fujita Tornado Damage Scale - NOAA/NWS Storm Prediction Center
Without a thorough engineering analysis of tornado damage in any event, the actual wind speeds needed to cause that damage are unknown. The Enhanced F-scale was implemented in February 2007.
Enhanced Fujita scale - Wikipedia
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.
Fujita scale - Wikipedia
The Fujita scale (F-Scale; / f u ˈ dʒ iː t ə /), or Fujita–Pearson scale (FPP scale), is a scale for rating tornado intensity, based primarily on the damage tornadoes inflict on human-built structures and vegetation.

Significant tornado: 113-157 mph: Considerable damage. Roofs torn off frame houses; mobile homes demolished; boxcars pushed over; large trees snapped or uprooted; light object missiles generated. F3: Severe tornado: 158-206 mph: Roof and some walls torn off well constructed houses; trains overturned; most trees in forest uprooted: F4 ...

What is the Fujita Scale for tornadoes? - University of Chicago News
Fujita described the damage that F4 tornadoes cause as: “Whole frame houses leveled, leaving piles of debris; steel structures badly damaged; trees debarked by small flying debris; cars and trains thrown some distances or rolled considerable distances; large missiles generated.” The F Scale quickly impacted the field of meteorology.
Fujita Tornado Damage Scale - National Weather Service
F3 Severe Tornado Winds 158 to 206 mph, producing severe damage. Roofs and some walls torn off well-constructed houses; trains overturned; most trees in forest uprooted; heavy cars lifted off the ground and thrown.
Enhanced F Scale for Tornado Damage - NOAA/NWS Storm Prediction Center
Enhanced F Scale for Tornado Damage. An update to the the original F-scale by a team of meteorologists and wind engineers, implemented in the U.S. on 1 February 2007.
The Fujita Tornado Damage Scale - National Weather Service
The Fujita Tornado Scale, usually referred to as the F-Scale, classifies tornadoes based on the resulting damage. This scale was developed by Dr. T. Theodore Fujita (University of Chicago) in 1971.
Storm Prediction Center Enhanced Fujita Scale (EF Scale)
The Fujita Scale is a well known scale that uses damage caused by a tornado and relates the damage to the fastest 1/4-mile wind at the height of a damaged structure. Fujita's scale was designed to connect smoothly the Beaufort Scale (B) with the speed of sound atmospheric scale, or Mach speed (M).
