User:WeatherWriter/Possible F5 and EF5 tornadoes

Possible F5/EF5/T10+ tornadoes officially rated F4/EF4/T9 or lower
Because the distinctions between F4/EF4/T9 and F5/EF5/T10 tornadoes are often ambiguous, the official ratings of numerous other tornadoes formally rated below F5/EF5/T10 or equivalent have been disputed, with certain government sources or independent studies contradicting the official record. This list includes tornadoes rated F5/EF5/IF5/T10 by government meteorologists, non-government employeed tornado experts (i.e. Thomas P. Grazulis or Ted Fujita) or meteorological research institutions (i.e. European Severe Storms Laboratory) that rated a tornado differently than the official government organization in charge of the rating. Published academic papers or presentations at academically held meteorological conferences that rate tornadoes as F5/EF5/IF5/T10 or present some evidence to support damage or winds in that category are also ways a tornado can be added to this list. This list can also include tornadoes previously officially rated as an F5 or EF5, but have since been downgraded officially to a lower rating.

Possible F5/EF5/T10+ tornadoes with no official rating
Many other tornadoes have never been formally rated by an official government source but have nonetheless been described as F5/EF5/T10+ or equivalent, often by independent studies. Most of these tornadoes occurred prior to 1950, before tornadoes were rated according to standardized damage assessments, and their unofficial classifications as F5/EF5/T10+ or equivalent have been made in retrospect, largely on the basis of photographic analysis and eyewitness accounts. A few, such as the Tri-State Tornado of 1925, are widely accepted as F5/EF5/T10+ tornadoes, despite not being rated as such in official records.
