Significant Tornado Events

[carolinas12]

Over the course of the past few weeks, I've been working to map out the "Carolinas" tornado outbreak of March 28, 1984, using damage reports and satellite imagery. Despite being quite an oddity in terms of its location and intensity, the tornado outbreak has largely fallen into obscurity over the years. In turn, details about the tornadoes and the damage they left behind are scarce. I have gathered a few photos of tornadic damage from the event through newspaper and other sources, although few tell of the worst damage from the outbreak. I've observed that this forum has a sort of knack for discovering niche photos of tornadoes and their damages, so I was wondering if anyone was willing to help me in discovering any new media of the event. Thanks!

Number 1 violent tornado ever?

First true aerial photo of the Flint Beecher tornado, really highlights just how narrow it was.
The fact that such a high death toll all came from a single trip of houses is something I can’t imagine happening again today.
I would say that the only comparable modern day example is Joplin, but that was a giant wedge that went through an entire town.

The full width was about half a mile wide, the intense core was what was really narrow.

Disregard; appears to be an undocumented tornado NW of Greeneville, TN. I've sent it to MRX as a friend of mine was able to find associated damage.

Okay so apparently NWS offices across the country are currently under some sort of order not to change any historical tornado records. From MRX:

Our team has completed a preliminary review of the materials you provided. Given the recent interest in historical events, there is a rather high bar and need for clear and compelling evidence to request changes. More broadly, the NWS is currently operating under a strict internal national moratorium regarding any additions, deletions, or modifications to historical tornado track databases. Because of this policy, local weather forecast offices are temporarily restricted from officially altering historical records.

I'm quite confused but meh, not a huge deal.

any of you guys have any questions or queries on the May 24, 2011 Piedmont, OK EF5? i'm hoping to test my knowledge here and maybe help some of you fellas out

Hey I am sure this tornado has been discussed in detail but gotta probably scroll back lol.

I actually do have some questions I’ve been wanting to ask for a while.

They’re regarding so called “trenched house”. Where was it located? Why is it missing from the DAT? How well was it constructed? What was it rated?

I can find next to no official information on this particular residence, despite it’s infamous reputation in online circles.

this home belonged to the Chronister family just off Highway 81. This was a home belonging to the same family.


While I'm not 100% sure on what happened to the trenched home, i assume it was just badly scoured and mudblasted. It was located just east of Highway 81. There is no rating to my knowledge and I really don't know why its missing from DAT, but I've read that surveyors say it was likely EF5 strength above this residence.

Just a few photos I have. I have to be careful with what I send since a lot of photos are private for whatever reason. Any more questions?

Has the specific windspeed needed to overturn the Cactus oil rig ever actually been calculated?

Has the specific windspeed needed to overturn the Cactus oil rig ever actually been calculated?

not to my knowledge. i feel its way too mathematically complex to get a windspeed off of that. there are different objects at Cactus 117 that could get a calculation done, like the 150 ton winch tossed or multi-ton cargo containers being lofted. i don't think we'll ever get an actual wind estimate of the rig.

This is going to be my last post on TW for a good while, and to round it off of course I'm going to talk about 4/27/2011 because why in the world would I not:

The Cordova, AL EF4 actually appears to be multiple different tornadoes, all probably violent, that were lumped in as one in the official survey; a few people off-forum have brought this up over the last few months and looking into it I really can't argue. Here's a photo set by Don Guthrie showing what I think is the main Cordova tornado (the one that hit town) touching down near Parrish - this is separate to the one that was borderline causing EF5 damage while a stovepipe near New Lexington:

GeoDESY backs up the fact it lifted:

It would've been impossible for the tornado to shift into the imagery gap while producing no apparent treefall of any sort so I think it's very, very likely this is a cycle of some kind. And if all this wasn't enough, I think this solidifies it, we have another angle of it while it was first touching down near Parrish:

This is not the look of an EF3 tornado about to go into a town; this looks either like a very unhealthy tornado about to die off or one that touched down moments before the video was taken.

To round it off it's worth bringing up The Coleman/Peters video; while I do think the tornado is down the entire time there it had already cycled by the time the video was taken and thus it doesn't appear to lift in the video. This lines up with the GeoDESY gap.

Little bonus: This is what the New Lexington EF5 looked like:

Friend of mine (Tijn) managed to geolocate this and confirmed this is both "Cordova" and whille it was doing borderline EF5-level vegetation damage.

The downside? Cordova's track length is cut almost in half. The upside? With this finding the violent tornado count might be pushed further up into the realm of what actually happened that day. Worth noting that there's a third possible cycle within the track that I haven't looked into yet and can't confirm nor deny.
