I'm still trying to figure out what the point of sending another survey team to Bremen is. An area where they have already deemed all of the most intense damage to be EF4, and where there will be pretty much nothing left to survey after cleanup except maybe some contextual damage. If we do get a context based EF5 that would be absolutely phenomenal, but I think we all know it's pretty clear where they stand at this point.
It was initially rated as an elementary school at 170 mph, which is actually below the EXP bound for DOD 10 (176 mph), and it appears this structure was built considerably better than the standard ES.
There was an EF4 180 DI in Dawson Springs but it got removed.
What annoys me is how many, if not most NWS mets tend to be extremely dismissive of vegetation damage, particularly scouring. They say things like, "an EF2 or EF3 can scour the ground, all it takes is debris." Or "Soils have too much variance across various regions of the US, and we don't understand how things like moisture content play a role in scouring." Logic wise, that holds up, but when you're nerds like us who have been looking into countless tornado events for decades, and analyzed a ridiculous amount of damage photos, the correlation between severe ground scouring and high-end events is undeniable. Much like what I do when the topic of debarking comes up, I say "Ok. Then show me an instance of severe ground scouring within an area that sustained classic EF2 to EF3 structural damage." It just doesn't happen. Then the backpedaling to "Well you can't do wind engineering tests on grass, and there's no scouring DI on the scale so..." Yeah it doesn't matter. If one were to collect incidents of significant scouring, and compare it to the type of structural damage that occurred nearby, I absolutely guarantee that one would find an undeniable correlation. The more you press, the more everything just starts to sound like an excuse...
But why? It looks no different than all the other countless CMU foundation homes that were obliterated throughout the town. How is this one different from the rest?This is the Dawson Springs DI:
Why would it be rated so low? I thought it was at least high-end EF4 tornado damage from what I could tell but it sounds like it was probably EF5 tornado damage.
I also don’t see how this is more intense than the CMU foundation houses that were completely swept away in Bremen.
That's funny because I did a couple of days ago in another thread. The exact same scene.
Is this almost Philadelphia like trench digging?
You can put them side by side and see the striking similarity. Not quite as deep as the worst scouring in Philadelphia, but still well into the EF5 category imo.
