Severe WX April 1-2 (overnight) Severe Weather Event

Side question because I’m not familiar with the terminology: What is a “continuous load path?” Does it have to do with debris impacts?

I'm glad you asked. A continuous load path refers to how forces, like wind, uplift, and lateral pressure, are transferred from the roof, down through the walls, and into the foundation. Each connection in the structure needs to be strong so the forces can move all the way to the ground without breaking the chain. It doesn’t have to do with debris impacts, but rather how the structure holds together under stress.

I don't care it should be rated EF4. I am sick and tired of all these nit picky excuses to not rate a tornado as EF4 and EF5. MEG is also a notoriously stupid office.
 
Yup, I don’t think anyone is surprised here. Remember when I lamented about realizing that MEG would be doing the Lake City survey? I wasn’t making a joke. This EXACTLY what I was worried about, and it further validates the bad reputation that office has earned over the years when it comes to botched, overly conservative damage surveys. In most other WFOs, we’d be looking at an EF4 rating.

I shouldn’t be able to accurately predict a botched damage survey days in advance just based on the WFO alone. What an absolute joke. This is just straight up abuse of the EF scale.

You the surveyor you know that this being extremely nit picky in rating tornadoes EF4 or EF5. Honestly, what would be wrong in calling the house as a 170 mph EF4 than a 160 mph EF3. Pretty much nothing. This construction was much better than the Newnan, GA tornado for 4 years and it was improperly rated EF4.

Of course the minute I knew them violent tornadoes that had done EF4 damage and which NWS office that was doing the survey I knew the fate of those tornado ratings had been sealed.

Which other EF4 DI from this decade would that lake city home be most comparable to?

Similar to the EF4 house in Tylertown, MS. Well-anchored house mostly, but not totally slabbed, debris piled on and near the foundation. Low to mid-range EF4. The only difference is the Tylertown house was a bit larger.

If JAN was surveying, we’d have an EF4 rating, no doubt.

Tell MEG that JAN makes them look like a steaming pile of cow dung.

That particular house was surveyed by New Orleans. But due to the generous EF4 di at the end of that track in Jackson’s CWA the point still stands strong.

Now I’m shocked that MEG of all cwa’s deterrmined the tristate tornado from 2021 to be an EF4.

I’m still annoyed they didn’t rate the extraordinary tree debarking near Buckeye, AR EF4. It is 100% up there with some of the most violent tree damage i’ve ever seen and was eerily reminiscent of Bassfield.

I mean goodness…

Jackson 2008....EF4(170 mph)
Smithville 2011...EF5(205 mph)
Holly Springs 2015....EF4(170 mph)
Tri-State 2021....EF4(170 mph)

These are the only four tornadoes I have known over the past 15 to 20 years that MEG gave EF4+ ratings to. All four of them still did stronger damage than the windspeed assigned to them.

Tri State was pretty accurate in my opinion. The homes it swept away weren’t of superb construction if I remember.
