The Enhanced Fujita scale (EF-Scale) rates the strength of tornadoes in the United States and Canada based on the damage they cause.
Implemented in place of the Fujita scale introduced in 1971 by Tetsuya Theodore Fujita, it began operational use in the United States on February 1, 2007, followed by Canada on April 1, 2013. The scale has the same basic design as the original Fujita scale—six categories from zero to five, representing increasing degrees of damage. It was revised to reflect better examinations of tornado damage surveys, so as to align wind speeds more closely with associated storm damage. Better standardizing and elucidating what was previously subjective and ambiguous, it also adds more types of structures and vegetation, expands degrees of damage, and better accounts for variables such as differences in construction quality.
The new scale was publicly unveiled by the National Weather Service at a conference of the American Meteorological Society in Atlanta on February 2, 2006. It was developed from 2000 to 2004 by the Fujita Scale Enhancement Project of the Wind Science and Engineering Research Center at Texas Tech University, which brought together dozens of expert meteorologists and civil engineers in addition to its own resources.

Clem Schultz records tornado in 2nd story of his home as the tornado passes right through it. Clem Schultz was sure the tornado weather forecasters were warning about was going to miss him, but he knew based on experience his Fairdale home would lose electricity. So he went to an upstairs bedroom to get camping lanterns he and his wife, Geri, would surely be using early on the evening of April 9 last year. He looked out a window and spotted a tornado to the west. He speculated it would stay south of his community, population around 150, about 19 miles northwest of DeKalb. He decided to record its passage on his cellphone camera. But that black monster had other intentions, hopping the railroad tracks a block away. There was no time for the 85-year-old to hurry back downstairs to the ...
