There is no "category" for winds in a tornado. Tornadoes are measured by the Enhanced Fujita Scale, which simply is a rating based on the amount of damage done. It ranges from weakest EF-0, to strongest EF-5....250mph winds are "capable" of producing EF-5 damage, should it move over certain sturdy structures. However, a tornado over an open field with 250mph will not get an EF-5 rating because it has no sturdy structures for it to damage. Tornadoes are rated after the fact based on the amount of damage done. So while a 250mph wind "could" produce EF-5 damage, it's got to move over the right structures for that damage to be realized and the tornado given that rating.
The highest category tornado is a F5 or EF5
The Xenia, Ohio tornado of April 3, 1974 was an F5, the strongest category of tornado.
The most powerful category of tornado is F5 on the Fujita scale or EF5 on the Enhanced Fujita Scale.
In terms of wind speed an EF5 tornado (estimated winds over 200mph, formerly 261-318) is stronger than a category 5 hurricane (over 155 mph). But overall a category 5 hurricane releases more energy.
The most dangerous category of tornado is EF5. It is the most dangerous because it is the strongest and the most destructive level of tornado. In an EF5 tornado well built houses will be completely blown away and disintegrate, so even being in the basement does not guarantee survival. These tornadoes produce large debris flying at high speeds that will result in serious injury or death if it strikes a person.
