List of F5/EF5 tornadoes

This page documents the tornadoes in which I have judged to have been an F5 or EF5. Sources used to reach this conclusion may include damage surveys, image s of the destruction, reports, or witness accounts. Some tornadoes have been raised to, or downgraded from F5/EF5, but most of the tornadoes here will be listed in official records as F5/EF5 events. NOTE: Tornadoes before 2007 in the US were rated using the Fujita scale prior to February 1, 2007, and in Canada prior to March 2, 2011, when the Enhanced Fujita Scale came into operational use. Ratings after this time elsewhere are rated using either the TORRO scale (if in Europe), or the Fujita Scale, unless otherwise noted. Winds estimated using the old Fujita Scale will be much higher than those of the Enhanced Fujita Scale, due to the older scale having higher wind speed estimates.
