Yeah CAMs did excellently with that. I'd suspected for a day or two in advance there would be a cluster practically overhead spitting tornadoes on that thermal boundary and that indeed happened to a grand scale. Very memorable event

But again, what was the structural integrity of it?Closer shot. This was indeed a house!

They didn't finish the survey yet. I don't believe.I'm a little annoyed that the EF scale requires a massively overbuilt house before EF5 will be considered. Since literally no one builds houses massively above code, that practically eliminates the chance of an EF5 rating in 99% of violent tornadoes unless they strike a big city. I would MUCH rather see EF5 start at 'average' homes with decent anchoring being swept, rowed, and scoured (which currently rarely gets rated above 170-175) with mid-end EF5 (210) reserved for the overbuilt nuclear bunkers they currently want to see shredded for a low end EF5.
NWS in New Orleans saw the house that was slabbed and had the anchor bolts ripped out. They said it will be considered in the final EF rating.They haven't even gotten much past Bassfield yet as far as I know so there's a lot of survey to go; the EF complaint applies to all tornadoes though not just this one. Not that I'm jumping on the "BASSFIELD OBVIOUSLY EF5 REEEEE" bandwagon, but the EF scale is deliberately set up to make it very hard for house damage to be rated that high. That would be okay if F5 wasn't handed out like candy in 1970s-1990s for much lesser damage, rendering comparisons for EF5s vs F5s completely impossible.
My gripe about it is that I think the wind estimates at the high end of the scale are too low.They haven't even gotten much past Bassfield yet as far as I know so there's a lot of survey to go; the EF complaint applies to all tornadoes though not just this one.

I think maybe somewhat but they probably are lower than the 261 mph which started the F5 category on the F-scale.My gripe about it is that I think the wind estimates at the high end of the scale are too low.
Probably. What would be the ideal wind speed to start the EF-5 range in your view?I think maybe somewhat but they probably are lower than the 261 mph which started the F5 category on the F-scale.
I would guess around 230 mph. Historically I believe most F5 and EF5 tornadoes had winds of 250+ mph.Probably. What would be the ideal wind speed to start the EF-5 range in your view?
Well I think the range of the EF-4 category should exceed 200 mph for sure.Honestly it might turn out that the actual winds are right in between the F and EF scale estimates. But that's something we will probably never know with absolute confidence
230 mph is approximately 200 kts. I say change the mph values to kts, maybe that would be more accurate.I would guess around 230 mph. Historically I believe most F5 and EF5 tornadoes had winds of 250+ mph.
20 tornadoes in Alabama alone Sunday...that puts us at #5 in all-time tornado outbreaks for this state. Unless we add 3 more, we will remain at #5.
