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 Moore, Oklahoma tornado of May 20, 2013, is the most recent tornado to be rated EF5 as of 2025. The Xenia, Ohio, F5 tornado of April 3, 1974.This was one of two tornadoes to receive a preliminary rating of F6, which was downgraded later to a rating of F5.
The instantaneous velocity readings taken are not directly equivalent to the three-second gust at 33 feet (10 m) that the Enhanced Fujita scale attempts to estimate, but they mark the second-highest wind speed ever recorded in a tornado, after wind speeds of approximately 135 m/s (300 mph) were recorded in both the 1999 Bridge Creek–Moore ...
The 1977 Birmingham–Smithfield F5 tornado's damage was surveyed by Ted Fujita and he "toyed with the idea of rating the Smithfield tornado an F6". [13] In 2001, tornado expert Thomas P. Grazulis stated in his book F5–F6 Tornadoes; "In my opinion, if there ever was an F6 tornado caught on video, it was the Pampa, Texas tornado of 1995". [14]
The EF Scale, used to assess wind speeds and damages of a tornado, incorporates 28 damage indicators such as building type, structures, and trees. The scale became operational in 2007 and is a ...
Before the Moore tornado, the blockbuster tornado season in 2011 led to the confirmation of five EF5 twisters, including the Joplin, Missouri, EF5 that killed 161 people. A total of 50 tornadoes ...
The F5 tornado was estimated to be about a mile wide and had winds over 300 mph. It traveled at a record speed of 73 mph and destroyed more than 19 communities, including over 15,000 homes.
The International Fujita scale (abbreviated as IF-Scale) is a scale that 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 ...
