Official F5 Tornadoes
The tornadoes on this list have been officially rated F5 by an official government source. Unless otherwise noted, the tornadoes on this list have been rated F5 by the National Weather Service, as shown in the archives of the Storm Prediction Center and National Climatic Data Center.
No tornadoes before 1950 were officially ranked F5, due to inadequate engineering data and other information on the historical tornadoes. From 1950 - 1970 tornadoes were assessed retrospectively, primarily using information recorded in government databases, and newspaper photographs and descriptions. Beginning in 1971, tornadoes were rated by the NWS using on-site damage surveys.
For United States tornadoes as of February 1, 2007, the Fujita scale has been recalibrated to more accurately match tornado speeds with their damage and to augment and refine damage descriptors. The new system is called the Enhanced Fujita scale. No earlier tornadoes will be reclassified, and no new tornadoes in the United States will be rated F5.
In all, 50 tornadoes have been officially rated F5:

Famous quotes containing the word official:
“I know one husband and wife who, whatever the official reasons given to the court for the break up of their marriage, were really divorced because the husband believed that nobody ought to read while he was talking and the wife that nobody ought to talk while she was reading.”
—Vera Brittain (1893–1970)
