What category is a 250mph tornado?
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.
