Enhanced Fujita Ratings Debate Thread

Union said:
Mayfield does have a quite likely, maybe for sure EF5 DI in the form of a large heritage church in downtown Mayfield, it was considerably better built than the rest of downtown and on the new CARB DI (according to Nick Krasz as well) it would fit pretty well into EF5, it was not rated in the original survey as the structure did not have a specific DI that fits it, there was a thin, violent stretch of winds before the church that quickly fell apart after demolishing it. Without further official analysis tho I guess we'll never know.

Wait, the CARB DI goes to EF5? I want the source now, if that is true then I can remove all doubt about Mayfield's EF5 rating likeliness.

To be honest - having once thought Bassfield was an 'Okay' 190mph and wasn't completely obviously EF5 - I have drifted more recently to it being EF5 and this video seals the deal. This is literally textbook EF5 damage - a well built home was swept away cleanly. What's more the sill plates were almost entirely removed and the anchor bolts were bent, and in some cases bent out of the concrete. Wow. I had initially thought the smooth flat appearance to the foundation on DAT meant it was less well engineered (not quite sure what made me think that but oh well) but now I know its a testament to how thoroughly the foundation was swept.

The fact those trees are debarked, 'rootballed' and then thrown is very impressive. Also the car thrown a very long distance (looks around 200-300m at least) and some scouring seems to easily support pushing slightly over the 'EXP 200mph' threshold into EF5. This combination of context and structural damage in close proximity is pretty rare.

The only mitigating factors would be the hypothesized vehicle impact (though in my personal opinion if the winds were strong enough that the car gained enough velocity to sweep the house in that short distance between the drive and the house then they would have been strong enough to sweep the house anyway), and the fact that the debris granulation is not as extreme in some cases we have seen at EF5 intensity.

But I think in all honesty this could be one of the most clear-cut textbook EF5 indicators from all our EF4s so far (likely with Vilonia, arguably Bremen, and a couple others). If this home was say in Rolling Fork, I don't think its too far fetched to say they would have gone EF5 as this seems a level above the 195 structure (IMO).

Two things to consider:

1. The "House" was basically a shack - literally apparently with a "Tin roof! Rusted!", like in the song IIRC. It was well anchored, but it was still a shack.
2. The surveyors established that it took basically a DIRECT hit from the truck. Like, they actually found where paint swapped and everything. EF4 is fine there.

That said, if root ball displacement occurred en masse, that would be EF5 on the new scale depending on if the trees were stronger than typical resistance.

Wow.

There you go. @buckeye05, @TH2002, we have it. A guaranteed EF5 DI from Mayfield.

I can't wait for them to reanalyze this one.

Sweet. Someone get this info to nws Paducah. Retroactive upgrades based on old damage photo’s shouldn’t be unviable right? If this Di info is accurate then Mayfield should absolutely be upgraded. Enderlin set the precedent. Time too follow through.

Literally everyone throughout the weather community in the week after the survey was just waiting for that ONE Di to be located that would justify an upgrade to EF5 for Mayfield. Now, we have it. Can’t just ignore it or science wouldn’t be adhered too.
Right…?

I can't believe it.

We now have a genuine, guaranteed EF-5 from Mayfield.

I hope they re-analyze Mayfield and give it the rating it deserves. I wonder if someone can contact NWS PAH and get them this info.
 
This right here. Is our EF5 Di candidate for Mayfield. If proven viable on the new scale (if nick’s source is accurate. But I don’t see why it wouldn’t be.)

If the nws is finally ready to cut it with the one Di isn’t enough balony. But even then there’s the tree damage in Bremen that could count as an EF5 Di on the new scale as well.

1. It was not a shack. Metal roofs are common in rural areas because they are very low maintenance. The cabin had a full interior and frame like any typical home. Just because something has a metal roof doesn't mean its cheap.
2. This doesn't necessarily mean the truck was shot through the house like a cannon. It was parked literally outside it, so the cabin and truck likely went simultaneously, and as the truck was being pulled through the exploding cabin it got wrapped up in all the wiring.
 
After 3 years of wondering how such an insane tornado couldn’t verify as an EF5. New info on a potentially viable EF5 Di on an updated scale that was being made in part to fix the issue of under-rated tornadoes is always gonna be great news and thus exciting. Especially when initial talks to re analyze past tornadoes are beginning.

For construction quality, I understand if some random guy on discord isn't good enough proof, but the guy in the photo I assure you is really good at this masonry stuff and looked at a lottt of imagery, the only things that really secured it were the up close images from Tim Marshall on his Facebook, Nick Krasz opinion on the quality/alignment with LB,EXP,UB details as well. The person in the screenshots explaining the construction doesn't think it should line up with the entirely UB class (but instead between EXP and UB), but according to Nick the points put out fit with UB well, though once again there could be stuff we don't know technically and how the NWS would rate it is unknown until further analysis if it's done.

Can’t believe i’m saying this, but Mayfield seriously has a shot at finally getting the rating it truly deserves.

The area leading up to the church was a good bit more intense compared to the rest of downtown Mayfield, it started near the water tower then crossed a moderately sized empty area before swiping away what I believe to be some sort of MBS(?), it then hit a newly built Myers Flooring Store building, rated with WHB max DOD it was rated 157mph before hitting the church, an IB next to the church sustained likely still EF3 damage but I believe the subvort which caused the rest of the prior damage quickly died after the church, cars were thrown into the backside of Myers flooring including a large box truck, not a ton of bodily mangling but rolling and lofting was consistent. I don't think it's the biggest slam dunk ever but it's just how it is based on imagery.download_22.jpgimage-157.pngimage-307.pngScreenshot_20250927-191622-1.pngFB_IMG_1760237806056.jpgScreenshot_20251009-010750.png

Of course this is just ranging it on the scale, but this proves my suspicions Matador was pretty high end. Also, here's this:
The car damage from Matador WILL NEVER cease to amaze me. If you rate it on houses, it maxes out at like mid end EF4, if on contextuals, i think it's EF5

For real @WeathermanLeprechaun. Like car damage like that should be taken into consideration.
