I say it depends on the quality of construction, that would be the difference between EF4 and EF5.
The hospital damage was probably EF3, the houses around it EF4. But there may have been EF5 damage elsewhere.
If you can find a before and after picture of the St John's Hospital you will be surprised by how devastated it actually is.
There is nothing except rubble as far as the eye can see. I saw not one wall even standing. Part of the equation is the quality of construction, but from what I saw that hospital was pretty well trashed and to say the least it is a substantial structure. An EF5 designation would not surprise me, but imo EF4 is a definite.
Agreed EF4 for sure. The only question mark is quality of construction of the houses surrounding it. I don't know enough about them to make the decision between EF4 and EF5. The hospital's condition (upper floors gone but not total destruction, EFKit has that between high EF2 and low EF4) would make me want to only go to EF4 though (winds about 180 mph there), thinking their construction is not at perfect shape. However, that is just one part of the track.
A permanent house with a slab swept clean (FR12 DOD10) ranges from 165 to 220 mph, with 200 mph expected.
Either way, any violent tornado is EXTREMELY dangerous and you need to be in a hardened safe room or underground to have a good chance at surviving!
