Severe WX December 10 & 11, 2021 Severe Threat

[andyhb]

The residential structures in Dawson Springs, Bremen, Earlington, and Cambridge Shores do not seem to be notably different from those that were impacted in Mayfield. So far the images from these locations indicate low-end EF4 as a possible ceiling, barring other DIs nearby that have not yet been documented. The high death toll from this event was likely related to its fast movement and occurrence after dark rather than an exceptional (by EF4+ standards) intensity, along with its having successively impacted populated areas.

Please just stop.

Greensburg KS and Spencer SD tornadoes took down water towers, but they were the old truss leg style and not a big modern one like this; even the Smithville MS tornado didn't take down the modern water tower downtown. It's an extraordinary indicator of intensity imo

Didn't Smithville also take a smack from an airborne vehicle and remain standing?

Edit: Disregard, saw someone else had confirmed in a separate post.

I wouldn't rush to assume what the construction of the homes along the ENTIRE PATH was based on Mayfield (which was literally 2 PERCENT of the path) alone.

On another forum I'm a member of (not a weather forum) a member's wife was in the candle factory during the tornado. She escaped with a co-worker through a hole in the roof after the building collapsed. Didn't provide any details on fatalities.

Anyone have recommendations on legitimate charitable foundations for donation?

Catholic Charities of Northern Kentucky is raising funds for tornado relief. Over 90% of money donated goes to the actual cause.

Bishop Medley Requests Prayers and Special Collection for Tornado and Storm Victims

Dear Parishes,In light of the recent catastrophic devastation across our diocese, I am requesting that each parish takes up a special collection at this weekend’s Masses. Many of those injured in the Mayfield candle factory were parishioners, and others represented migrants and the marginalize...

Here's a list that includes some local organizations, which is usually your best bet for making an immediate impact:

I've also seen several local officials recommend the Western KY Red Cross, which is what I'll probably choose.

Edit: Not sure why my Western KY Red Cross link isn't working, but it's easy to find anyway.

Any word from Princeton?

How's that for an EF5 level of damage?
It's near Breman KY.

It's not a direct damage indicator but I'm sure the engineering survey will take it into account and it could help bolster a very high end rating should they consider it

Should be able to get pretty specific information for the wind load rating from the design documents, submittals, and as-builts, but I'm not a structural engineer.

ANSI/AWWA D100-11 3.1.4 seems to be the standard that covers wind load ratings for structures like this and it uses ASCE 7-10 for doing the wind load calculations using the usual basic wind map. I would imagine a water tower of this height would be something like a risk category IV, but again I don't do structural

Bottom line, a structural engineer will be able to get VERY good data for this structure, and with this being a violent tornado there will obviously be several structural engineers at minimum involved with the QRT, survey, and ratings process.

I've no idea what is a common wind load rating for one of these towers, but it is an EXTREMELY important piece of the engineering process for a structure like this so it will be well-documented.

Still some debris on the slabs but the contextual evidence is very very strong. Ground scarring, no trees or bushes left standing, that's a sign of very very high-end damage.

That reminds me of some of the vehicle damage we saw from Smithville.

Bowling Green area.

This photograph from Dawson Springs was found in New Albany, IN. Using google maps to do a rough measurement, that's like 125 miles.

This says a lot right here. Jeff was first on scene to the aftermath of Joplin.

No words..

 

[TH2002]

Anyone have any photos/information from the first tornado? Haven't seen much except for the nursing home in Arkansas and the scouring in Samburg. I know there are fatalities but does anyone have a preliminary count?

I'm pretty sure they will be examining and analyzing this particular tornado for a long time. There is a problem with communication as you would expect from the storm site so I wouldn't get too wrapped up in trying to figure out if it is a F5 or not since we are still really getting a trickle in of information
