What is the damage of an EF3 tornado?

An EF3 tornado will partially or mostly destroy a well built house, removing the roof and collapsing exterior walls and some interior walls, sometimes leaving only a few standing. Weaker structures may be leveled and poorly anchored ones may be blown some distance. Most trees in the path of an EF3 tornado will be uprooted or snapped. Heavy vehicles may be lifted.

Note, however, that most structures in an EF3 tornado will suffer less than EF3 damage. If damage to even one structure is rated as EF3, then that will be the rating of the tornado.
