The Xenia, Ohio, F5 tornado of April 3, 1974.This was one of two tornadoes to receive a preliminary rating of F6, which was downgraded later to a rating of F5. [1]This is a list of tornadoes which have been officially or unofficially labeled as F5, EF5, IF5, T10-T11, the highest possible ratings on the various tornado intensity scales.
The old scale lists an F5 tornado as wind speeds of 261–318 mph (420–512 km/h), while the new scale lists an EF5 as a tornado with winds above 200 mph (322 km/h), found to be sufficient to cause the damage previously ascribed to the F5 range of wind speeds.
Here's how tornadoes are rated on the Enhanced Fujita scale and what those ratings mean.
Despite their relative rarity, the damage caused by EF5 tornadoes represents a disproportionate hazard to life and limb; since 1950 in the United States, only 59 tornadoes (0.1% of all reports) have been designated F5 or EF5, and yet these have been responsible for more than 1300 deaths and 14,000 injuries (21.5 and 13.6%, respectively).
Eleven years later, it remains the most recent tornado to be rated EF5, the strongest possible rating on the Enhanced Fujita Scale. The 11-year gap is the longest since official U.S. records began ...
