[43] [44] The same supercell responsible for the Kellerville tornado cycled and formed a violent tornado to the west of Allison, Texas. The tornado initially moved to the northeast at around 60 miles per hour with a maximum width of 1.25 miles before slowing significantly, turning to the west, and occluding similar to the tornado before it.
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 ...
The rate of occurrence drops off quickly with increasing strength—violent tornadoes (F4/T8 or stronger), account for less than one percent of all tornado reports. [6] Worldwide, strong tornadoes account for an even smaller percentage of total tornadoes. Violent tornadoes are extremely rare outside of the United States and Canada.
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]
Intensity cannot be determined due to a lack of information. This rating applies to tornadoes that traverse areas with no damage indicators, cause damage in an area that cannot be accessed by a survey, or cause damage that cannot be differentiated from that of another tornado. [4] N/A EF0: 65–85: 105–137 52.82% Minor damage.
The TORRO tornado intensity scale (or T-Scale) is a scale measuring tornado intensity between T0 and T11. It was proposed by Terence Meaden of the Tornado and Storm Research Organisation (TORRO) , a meteorological organisation in the United Kingdom , as an extension of the Beaufort scale .
The Baron Tornado Index (BTI), also called Vipir Tornado Index (VTI) is a meteorological computer model. Its main usage is to determine the probabilities of a tornado inside a Tornadic Vortex Signature on the rear flank of a storm, to better alert potential high-risk areas for tornadoes and to easily track them.
2023 Rolling Fork–Silver City tornado — A long-tracked, violent tornado directly impacted Rolling Fork and Silver City, as well as many surrounding areas, including Midnight, resulting in catastrophic damage. The tornado was at its peak intensity of high-end EF4 in Rolling Fork, destroying many homes, mobile homes, businesses, and other ...
