None of the tornadoes in the United States recorded before February 1, 2007, were re-categorized during and after the transition to the EF Scale. Essentially, there is no functional difference in how tornadoes are rated. The old ratings and new ratings are smoothly connected with a linear formula.
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] In 2023, it was announced by the Storm Prediction Center and National Weather Service Norman, Oklahoma that the 1970 Lubbock tornado was originally rated ...
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).

EF0 and EF1 tornadoes are considered "weak" tornadoes, EF2 and EF3 are classified as "strong" tornadoes, with winds of at least major hurricane force, where EF4 and EF5 are categorized as "violent" tornadoes, with winds corresponding to category 5 hurricane winds and rising to match or exceed the strongest tropical cyclones on record.
Around 60–70 percent [22] of tornadoes are designated EF1 or EF0, also known as "weak" tornadoes. But "weak" is a relative term for tornadoes, as even these can cause significant damage. F0 and F1 tornadoes are typically short-lived; since 1980, almost 75 percent of tornadoes rated weak stayed on the ground for 1 mile (1.6 km) or less. [17]
Hurricane Milton's tornadoes in Florida were a leading cause of death and damage from the storm. The U.S. has seen an abnormal number of intense tornadoes linked to hurricanes this year.
Propelled by Hurricane Milton, the tornado was the product of conditions including daytime heating, dry air, and swift changes to wind direction and speed that maximized its power, Miami-based ...
