Enhanced Fujita Ratings Debate Thread

They said it should have been corrected years ago on the comment. The house in question wasn’t ever really worthy of high end EF4 by the looks of it I guess.
I'm not impressed by this.

Shawnee was very violent

Yea I agree. but the DI rated 190mph was over-rated according to NWS Norman so they changed it. 13 years after the fact…
I Wonder what else they plan on changing.
 
@Central Ohio Wx has contacted many offices in the SE regarding undocumented strong tornadoes or different events and they always said that there was a strict policy for no changes in the database and no downgrades nor upgrades.

Makes me wonder what odd double standard this one has for Shawnee, and is there specific regional rules? If not then this is just straight up bending the rules from NWS Norman. Really odd decision. If that gets downgraded, upgrade Vilonia.

Regardless of Enderlin being rated as it was, it's important to note that NTP played a part in that. It seems like offices are still the same with picky standards. The fact the first EF5 in 12 years needed some input from across the border convinces me that Enderlin was just a one off. No wave of change or thinking from offices. The EF scale remains as problematic and offices contradicting so called "policies" doesn't make it any better.

Wasn't the first quoted post actually from Moore 5/20/2013?

This just isn’t true. I can’t say too much without breaching trust of my source, but it’s a very reliable one. But anyway, I can confirm that Enderlin definitely had an impact on the train of thought in high up places in the NWS. While things are on hold for the time being, there are people with the NWS who especially after Enderlin, want to take another look at various controversial tornado ratings from years prior. While things aren’t going to change right now, the motivation is there when it comes to the desire to take another look some time in the future. The only caveat would be if this policy is long term and keeps a stranglehold on any possibility of re-assessment until people just give up/move on. Anyway, that’s all I can say for now.

Also unrelated, but the Effingham, IL tornado provided ample examples of tree stubbing, and even low-end debarking occurring within the immediate vicinity of EF3, and even EF2 range structural damage. This isn’t typical, but it can happen. Now this isn’t the kind of debarking that is caused by high velocity debris or particulate. It more has to with the close proximity of trees to damaged/destroyed structures. As the structures come apart, the trees are within such close range, they are subject to a particularly concentrated blizzard of plywood, lumber, and other construction materials. The trees in the third pic had an entire detached garage (that’s not a house slab don’t worry) thrown into it. Essentially, this type of debarking is more representative of close range blunt force impacts than it is actual wind damage. Debarking that occurs farther away from structures or in rural areas is a whole different story, and arguably a different phenomenon.
