DAMAGE ANALYSIS: 2013 Moore, OK EF5 Tornado

[@tornadostories]

10 years to the day. I have a feeling that this video will be very well received on your channel. I'm going to make a cup of tea and watch this on the big screen. Peace✌️ 🇬🇧🕊️ 🇺🇸

[@Ryandupont0896]

10 years ago to the day I remember this like it was yesterday……however we’ll never know when we’ll get the next ef5

[@oish6684]

we’ve had many close calls since, could happen any time - let’s hope not

[@peachxtaehyung]

​@@kassieblackmon4761 there's no such thing...

[@ezera7616]

the tornado was not 2 miles wide, it was clocked in at 1.3 miles wide per NWS in norman oklahoma, it did NOTHING indicating F6 damage, as a matter of fact, the F scale has been retired, but not only that, "F6" is non-existent. do some actual research before saying bullshit like this

[@Nocturnal39]

Initially, Ted Fujita rated the Xenia tornado as an F6, but it was downgraded because, at the time, the Fujita Scale was still being made.

[@deathbloom27]

​@@kassieblackmon4761a few things. 1) it was not 2 miles wide, it was 1.08 miles. It had a large debris ball, but it wasn't 2 miles. 2) size doesn't affect the rating. You can have tiny ef5s and big ef3/2s. The widest tornado in recorded history was rated an ef3. That's never the scale is not exactly a strength scale, it's a damage scale. It measures the damage, that's it. 3) there is no such thing as an ef6. The ef5 rating covers everything an ef6 could have. It would have to be a supernatural tornado to reach the point that experts would consider an ef6 rating. Like 500mph winds and concrete foundations completely missing, no debris to be found anywhere, just gone. We're not even sure that is possible, if a storm like that exists. It's certainly never been seen or measured before.

[@Josh3B]

I once heard Tim Marshall say (In reference to the exponential power of tornadic wind)- that 200mph wind is actually more like 4 times more powerful than 100mph wind, and 300mph wind is more like 9 times as powerful. That's terrifying to contemplate.

[@junefirst]

Indeed! Kinetic Energy = 1/2 mass * velocity^2 Velocity is the dominant factor when it comes to kinetic energy, increasing exponentially.

[@trollerjakthetrollinggod-e7761]

I think that was Hunt for the Super twister.

[@Strob_GD]

@@junefirst Aye this is really late but what website are you using for the damage analysis? Where you can see the satellite imagery

[@junefirst]

@@Strob_GD I export the survey data from NWS Damage Assessment Toolkit and import into Google Earth Pro.

[@Strob_GD]

@@junefirst Weeeird, thanks SO much!

[@jmstudios457]

Never thought I'd find someone else who finds the damage side of tornadoes interesting. I started work on a video essay about a history of tornado forensics but it seems like you already have that covered. Looking forward to the next one, Amazing work!

[@deathbloom27]

There's a lot of really informative, in depth videos on this topic on KZbin. Just search tornado damage path and you'll find them.

[@Dahn.Baern.]

I live on 19th street in Moore. Thank God I didn’t live here at the time. My neighbors did, but they survived and have some amazing stories. Neighbor across the street had 2 children at Briarwood Elementary when this f5 hit.

[@cookracr]

My grandparents, my aunt, and cousins were in that house with F4 damage sandwiched between the F5s. All made it out nearly unscathed. My grandfather rode the 2012 and 1999 F5s out inside the house both times. Words cannot describe the damge I personally saw that day. My dad and I were among some of the first people at that 7-11. Digging through the rubble pile thatvwas the freezer hoping to find the woman with her baby will forever be burned into my memory. Great video.

[@dillyboyq]

The fact that this nader threw a 10 TON TANK over a MILE(!!!!!!!) I can’t even fathom that.. imagine getting swooped up by winds that strong

[@matthewjohnson2428]

Yeah, and not only the 210mph winds to move it, but the fact that they were sustained for that long in a vector that kept it aloft is unbelievable! I think it's safe to assume that it was more than 210 mph at times, at least above the surface

[@dannyllerenatv8635]

Make no mistake. This tornado was every bit as violent as the 4.27.2011 EF5s (yes, I'm going there). There is a VERY GOOD REASON why the NWS themselves compare this tornado to Smithville, Phil-Campbell, Hackleburg, and the May 3rd, 1999 F5s. This thing ripped and shredded plumbing and electrical routing out of foundations. Want to know what other tornadoes did this kind of damage? Jarrell and Smithville. Not only is this the last EF5 to occur as of the time of this comment, but it's also one of the most violent tornadoes in recorded history. This thing VERY much lives up to the title being "May 3rd, 1999, all over again".

[@joespaghetti9]

I cant believe this happened 10 years ago already. I remember it hitting about a mile south of where I lived. I remember being able to look at the sky from the south, and it was pitch black

[@ILoveOldTWC]

Moore - 24 fatalities. While even one is one too many, and every fatality is it's own personal tragedy, other single tornadoes in recent years beat Moore in terms of fatalities. Tuscaloosa, 2011 Super Outbreak, 44 deaths. Hackleburg-Phil Campbell, Alabama, also an EF-5 of similar intensity, with winds at 210 mph, and SEVENTY-TWO fatalities, beats Moore's count by 48 people. Joplin, 160 deaths. This tornado was only on the ground for 13 miles, but unfortunately, just happened to intensify while going through Moore. Hackleburg-Phil Campbell was a very long-tracked tornado and lasted 2 hours and 35 minutes, whereas Moore lasted 39 minutes. By the way, the previous day, May 19, 2013, had tornadoes. OKC's eastern suburbs got hit. Shawnee in Pottawatomie County, about 37 miles east of OKC got hit by an EF-4, and these storms probably put out outflow boundaries that enhanced the lift for the storms that spawned the 2013 Moore tornado. I do think that May 3, 1999, overall was worse, as it was a big outbreak, and not a single tornado.

[@SirRobbins]

Moore was an EF5 for about 5-10 seconds... Only 3 structures in its path were categorized as EF5 damage and they were 3 homes next to each other destroyed by a single sub-vortex. Hackleburg tornado was an EF5 for over 40 miles.... Joplin was disputed countless times to have no EF5 damage but poor construction throughout and EF4 will cause mass loss of life like Tuscaloosa.

[@TheWigglergler]

@@SirRobbins The dispute over the rating of the Joplin tornado was based on a very small sample size of buildings. As with every EF5 tornado, EF4 damage was much more common throughout and was as such easier to detect. Out of 7,964 buildings damaged or destroyed, the survey team that disputed the rating only surveyed 150. 22 homes in Joplin were assigned an EF5 rating, that is some of the most EF5 damage in any tornado since the scale came into effect. The Moore tornado had 9 EF5 DIs, not 3. In addition, these were rather spread out in three clusters that occurred at different points in the tornado's life. Given that many homes were swept away but assigned EF4 ratings due to construction being too poor to assign an EF5 rating, it is likely that the tornado was at EF5 intensity for longer than the official EF5 DIs indicate. It also was likely at peak intensity before it entered Moore. Although damage at the Orr Family Farm was only rated EF4 due to the relatively poor quality construction of the buildings there, the contextual damage indicated EF5 intensity. The surveyors themselves noted this. The contextual damage in this region was frankly more extreme than any contextual damage out of the Hackleburg-Phil Campbell tornado. Although the Moore tornado didn't maintain EF5 intensity for as long as that tornado, its intensity at its peak likely was quite similar.

[@tornadoclips2022]

I barely remember it but I saw the aftermath and I still remember seeing the cars tossed everywhere . I fell like this was the tornado that made me love weather and look at storms differently. Great video as always and R.I.P the victims of this tragic event

[@Jeremiah-f8h]

I can’t imagine EF 5. I’ve seen EF 4 in person and it’s surreal. To see that something stripped gravel roads down to their base and took pavement and it’s gravel base off the roads is unreal. The power is unimaginable.

[@bbybby91]

[@FrankReynolds182]

Yeah, tornado damage is frightening. I've personally witnessed EF4 and EF5 damage and it's shocking. Cars wrapped around trees, concrete sidewalks thrown into houses, housing complexes and brick buildings completely wiped from their foundations... it stays with you.

You are a pure soul. What you say at the end makes me cry. ❤ Thank you for the work you did, I from Italy and I don’t know nothing about tornado, you and your colleagues are an important resource for me. ❤

[@NovejSpeed3]

I lived in Moore when this storm hit. I was out of town but my wife and son were home this day. They hid in the bathtub of our central bathroom with a crib mattress on top of them. The tornado missed us by less than a mile. The guy who bought our house (i was moving to Atlanta to get my Mechanical Engineering degree LOL) wasn't so lucky. We put our house on the market on a Friday in July and we had an agreed contract (what we asked plus some) the Monday following! My son was born at that hospital this monster wiped off the map (it had to get torn down due to the level of destruction it sustained)! We were blessed!

[@Josh3B]

Another great video. I love these, because it adds that scientific aspect that we don't often think of for these damage indicators, and the perspective of an engineer really helps to explain some of this. Though I'm sure we've been close a time or two since 2013, I'm glad we haven't had an EF5 since a decade ago.

[@TheDude1980]

Please, keep up the great work! Loving these video’s!

[@klk1900]

So the Lubbock F5, joplin, greensburg, elreno, may 3rd. Multiple violent tornadoes have made that left turning corkscrew turn. It’s just something to think about chasing. We see it time and time again it may be revolving around the meso. The moore tornado you can see a merger and a 70kt jet streak +/-20kts. Right as it was entering. But also it could be the centrifugal force / debris throwing the tornado out of balance that causes that cork screw turn. If you look at damage paths. The cork screw turn happens when the meso starts shrinking. Usually the hook gets clogged up with a merger or something and the meso expands to cope with the inflow disruption. But when the hook clears, the meso shrinks rapidly (back to its original size). It’s almost like squeezing a water bottle or bulb syringe. It really funnels a lot of energy to the ground when the meso shrinks. It’s almost like it collapses all of that energy into the core of the tornado.

[@LITTLE1994]

I still cannot believe this STILL remains the last F5/EF5 tornado yet, after 11 years. But yes the 2013 one was indeed a repeat of the infamous 1999 F5.

[@JoePez]

Wow already 10 years huh? I remember hearing about this when I was like in 3rd grade. RIP all those who were lost.

[@tornadostories]

Another superb addition to the series. Great work 👍

[@katherinechapman558]

My dad tells me the story of when we lived in Naperville Illinois when I was a small child and an EF5 Tornado hit Plainfield Illinois which was about 10 miles from where we lived. A man he worked with was on his way to the Unileaver plant in Joliet Illinois when he stopped on the side of a highway because the rain and wind were to strong to continue. 5 minutes later a fence post went streight through the drivers side door and out the passengers side door leaving a hole about the size of a soccer ball. If he had stayed in the car he would've been skewered alive. In the aftermath of that storm 29 people were killed and over 300 were injured. They were pulling bodies out of cornfields up to two miles away from the town. Tornadoes are pretty to look at but one of mother natures most deadly phenominons. I have heard people say that being near a tornado like that sounds like being next to a freighy train or fighter jet taking off.

[@tommortlock8783]

I remember watching Michael Lynn's footage of this storm and you see how quickly it starts to widen after touchdown, highly recommend watching if you haven't seen it

[@lordmatthewanunnahybrid1356]

That footage is absolutely incredible. He literally drives his car right next to it the entire video.

[@MichaelLovely-mr6oh]

Of course I remember how Michael Lynn was talking on the phone with his daughter Jenna. He was urging Jenna to simply get her ass in the storm cellar and stay there until the storm had passed.

[@carlyannawx]

The INTRO? Everything is so good here

[@josephj6521]

Great analysis. It’s not only the ferocious wind but what comes with it… the debris smashing into everything making any tornado that much devastating.

[@Strype13]

Ethan, while these damage analyses are absolutely fantastic as they are... I'm curious if you have ever considered adding video clips and/or photographs of the tornados that correspond with the damaged areas being discussed? I haven't seen anybody take this particular approach and I think that level of detail would allow you to achieve the absolute pinnacle of individual tornado analysis. You're already including a weather synopsis, an overview of the tornado path, and detailed reports on damaged locations and structures (including the unfortunate casualties). The only thing missing is a visual representation of the phenomenon responsible for all of the destruction being examined. I realize there isn't always a video and/or photograph capturing every moment of these events -- far from it -- however, when one is available that allows you to determine its approximate location in correspondence with the damage path, I truly think this addition would be the proverbial icing on the cake in regard to providing the most informative and insightful analysis possible. Just figured I would offer a suggestion for you to consider for future videos. You are currently my favorite source on the entire KZbin platform when it comes to analytical tornado content and I think I speak for the vast majority of your viewers when I say we greatly appreciate the time and effort you put into these projects. Creating presentations that are simultaneously entertaining, captivating, and educational all at once is an incredibly difficult feat to pull off and your ability to accomplish this objective is beyond commendable. I cannot thank you enough for the outstanding content you provide for us, my friend. Please, keep up the amazing work, good sir. I am always looking forward to your next upload!

[@samuellambert6128]

Once again, a phenomenal review of a tornado event. I personally do not remember this happening because I was young and a couple hundred miles away.

[@MultiVortexTornado]

I remember watching a documentery called "Oklahoma Tornado Target" from The Weather Channel a few years ago and this was the first thing it showed before Moore 99 and El Reno

[@ef5hunter]

This is a very intellectual analysis of a major tornado event. For us technical nerds, it was a riveting watch. Very well done! BRAVO! I could watch it 100 times and gain a little further understanding and fascination each time. FWIW: I personally witnessed this tornado, but not until about the last few minutes of its life. Of hundreds of tornadoes I have witnessed in my life, this was one of the most audible. I could hear it clearly from a surprising distance. Others have reported the same. Curious why. Thank you for high quality content on KZbin!

[@carlyannawx]

PERFECT I cannot wait

[@jerryeubanks491]

This is the first day I found your KZbin channel very detailed report I do have a one question for you and I hope somehow you can answer it where did you get the data for the map and the EF scale I've been trying to locate this for the Barnsdall Bartlesville Oklahoma tornado last month but I can't find anything any help you can get me I appreciate I will be subscribing to your channel and hope to see more in the future

[@junefirst]

I download the survey data from the NWS Damage Assessment Toolkit and upload it into Google Earth

[@klk1900]

In 2011 I formed an opinion that It’s way easier to get a EF5 rating in tornado alley / Oklahoma 15-35mph vs Dixie alley 55-75mph. So take jarrell where the tornado was creeping 1-8mph at times. Or the cork screw turns produce DOD 10 on a FR12. The Dixie alley tornadoes were moving 55-73mph; so the core of the tornado that usually produces the DOD 10. It’s not over a location for very long moving those speeds. Sometimes less than 3 seconds -- also in 2011 I learned about the politics surrounding the Scale. The Hackelburg or smithville had those been moving 5mph I don’t even wanna think about what would’ve happened.

[@glennjohnson4628]

That's a really good point, I never thought about it like that. Obviously wind will do more damage if it sits in one spot so long. I wounder if they consider this in these situations

[@mikem.s.1183]

Excellent analysis, Ethan. There seems to be something lost in the midst of the discussions regarding classification of the class of tornado that hits cities, towns, locales. And that is EXACTLY what you touch on. You can have an EF3 destroy a house/place if the quality if buildings is not good. The damage indicators can resemble those of a higher intensity funnels, when in fact it's the quality of materials/construction that is at the root of the destruction. I think NIST looks into these often overlooked (by newsmedia and storm analysts), and this is of paramount importance to understand who or what is responsible for tragic events. Good videos, Ethan. Good service.

[@topaz6959]

I loved it, well represented and very informative, the math still puzzles me ahaha, but I have one question, when it comes to tornadoes I know they're capable of trenching and I wanted to know what it would take to pull a slab out of the ground or shift it, if possible?

[@junefirst]

Glad you loved it! Trenching, ground/pavement scouring is something that I'm still diving into. There are a lot of variables to consider that I'm not comfortable with covering yet in a video until I have a better foundational understanding. Stay tuned, I'll get to it when I figure it out!

[@topaz6959]

@@junefirst Appreciate it highly, I'll definitely be looking forward to that and all else you bring out!

[@DagonNaxos]

Kudos to you for your sensitivity and sensibilities when it comes to the damage and the human impact. However, I think that an EF3 would almost be worse to view the damage of, because with an EF5, stuff is so ground up into little bits that not much is really recognizable. An EF3 will shred a house, but you can mostly tell it's still a house, ya know? Just my 2 cents on it. Both are heartbreaking and the fact that anyone lives through these things is a blessing from God and a testimony to the vigilance of the NWS. Thanks for all that you do. As an engineer myself (computer not mechanical or structural) your analysis method and math skills make me smile. Excellent work, as always!

[@akirananimoto5843]

I was only 11 at the time, but we had passed through Joplin only 2 weeks after the EF5 and seeing the damage with my own eyes, it was astounding. I was young, I didn't understand a bunch, but the images were engraved in my mind, and looking back at it, now being 25, I just can't fathom it at all. That was the only tornado damage I have seen with my own eyes in all 25 years of my life, and it was devastating.

[@michaelnaretto3409]

Tornado updrafts are really something. They scour pavement off of roads, completely wipe away structures, debark trees, throw cars hundreds of yards away, tearing limbs off of people (yes, it has happened). It's crazy.

[@shizzle840]

I'll never forget this day. Living so close, it was a scary day for sure

[@Saltfly]

After looking at the damage and strength of the tornado it still shocking that more folks weren’t injured and killed. Absolutely crazy

I remember this day. I got home from High School, and decided to turn on the Weather Channel. I got to watch this Tornado from shortly after touchdown to rope out. My Dad has a saying that Today's news is tomorrow's history. It applies to weather too, and I got to see this beast make history. Haven't watched the video, but I remember saying to myself this is an EF4, but apparently it was an EF5.

[@jaym1244]

This is probably the most in-depth analysis of damage indicators I have ever seen. Very well done! But what's truly on my mind is, after 2 of the most devastating tornadoes in history, why would anyone ever rebuild in Moore, OK? Why anyone would live in tornado alley is beyond me but who would ever want to live in Moore again? Tornado insurance alone must be outrageous! I just can't fathom risking your life and the life of your loved ones, to live there.

[@Cleaning_Hero]

A lot of homes in the main neighborhoods hit had no walls left standing after the tornado passed through, especially homes in/near the center of the path. I wonder why they weren’t labeled with E-F5 indicators. Is it because the foundations and pavement wasn’t swept clean? Or is it because the house frames were not anchored well enough?

[@CoffeeonKorriban]

Very well done. I always appreciate this type of content. ☕

[@Jp-jn5bs]

I remember the day while living near Lawton, ok. I remember in our part of the statewe had some clouds, a bit windy, but overall, not bad. Around noonish, maybe around 1, we (folks at work) noticed this... dark, almost black mass in the horizon, looking NE towards OKC. It was ominous, and it looked nasty. A few hours later, we got the news that there was a massive tornado around okc. Some people who volunteered to help in moore described the damage as war like and hellish. Crazy!

[@vickyg6746]

i see a lot of people talk about the plaza towers, but see almost none mention the family that was swept into the oklahoma river because they sought shelter in a concrete tunnel. five people died in the tunnel alone, and four of them were children. they are buried by my sister and i think they deserve to be remembered as well. concrete tunnels are not good places to seek shelter! you will be swept away by flood water and will drown.

[@junefirst]

That took place in the El Reno event, just over a week after the Moore event. As a rule of thumb, always heave flash flood warnings to get above ground over tornado warnings. Flashing flooding is way more dangerous than most tornadoes. A similar scenario happened in Sept. 1st, 2021 outside of NYC.

[@duhdims]

[@nicholaspayne349]

I am completely fascinated with tornados and weather. I constantly watch videos about tornados and extreme weather and my wife hates it. She grew up in Moore and survived both the 99 and 2013 tornadoes. She does not like tornadoes, so every time we get supercells rolling over us she goes directly to the closet when the sirens go off. I’ll be watching radar like the meso is literally a half mile south of us we’re fine.

[@poohssmartbrother1146]

29:29 and that is the main flaw of the scale. The DI system relies on more data to be more accurate and with Tornadoes that's not a good thing. We could have a 2 mile wide 320mph+ beast cut through a field and rate it an EF3 cause it only clipped a single house. I think its also worth considering that the old scale had F4's go into the mid 200's and F5's were 250+. Having the EF5 tolerance right at 200 is clearly a problem. When its hard to differentiate a 190mph DI from a 210mph DI you will have this. Its also clear if you study F5's that had mindblowing levels of destruction (5/3/99, Jarrell, Candlestick, Lubbock, Xenia, 4/3/74, 4/4/77, 5/31/85) you can get a better idea of what true F5 damage looks like.

[@jeremiahmiller6431]

The main flaw of the EF scale is that it's being used to measure something it shouldn't be, the intensity of the tornado. It should solely be used to measure damage on the ground. With modern radar technology, we can use wind speed measured by radar and physical size to better indicate intensity than we can with damage.

[@offtopp1277]

Hard to say, I’d love to see that however, given it was 2007 and Canada, I don’t believe there would be any available maps such as this

[@alexis_ian]

Although not as violent and intensity as the Bridge Creek-Moore Tornado of 1999 its slower speed made it more distructive I think its among the slowest F5/EF5 tornado with Jarrell TX being the most notable. Its also surprising how this barely got an EF5 rating it may have received a High-end EF4 with how stringent the damage survey.

[@13_cmi]

10 years since the last ef5. Crazy. And joplin’s anniversary is in a couple days. It’s crazy when disaster dates line up like that.

[@junefirst]

May is peak severe weather season for the Southern Plains. Higher frequency of potent setups leads to the increase of high impact events this time of year.

[@bostonwarrior4824]

Amazing video. Please do Joplin next!!!!

[@fresto2208]

Wonderful channel, thank you for all your insight. I have a question for you. Of all the issues with the EF scale, one that I never hear talked about its the fact that there seems to be no accounting for the duration of winds over a damage indicator. As you point out in this video, the area where the storm cycled (or whatever it was that happened) yielded a greater concentration of EF-5 indicators in part because that's where the storm was going the slowest. The Jarrell event is probably the most famous example of this issue. The EF scale is supposed to measure wind speed. Doesn't the presence of a time component more or less undermine the whole thing? Over geologic time, an ant blowing on a house could probably slab it. I'd love to hear your thoughts on this.

[@junefirst]

You’re right, it’s not something often talked about. There is currently limited published research on how forward tornado motion contributes to intensity of damage, however, I know there is some on going as of right now (Tony Lyza is one researcher I know of that’s working on this topic). Like you said, Jarrell is the classic example of long duration over an area. However, it seems like some of the violent, fast moving tornadoes also contribute to greater damage thanks to the added forward speed, but the research has yet to be published. Awesome question!

[@fresto2208]

Afterwards our management asked the city (who owns the building) what tornado rating the building was built to withstand. The OKC response was it was built to code. Needless to say we are told to work from home during days when severe weather is expected to produce tornados One thing I disagree with the poster of this video. We were expecting extremely severe weather with a week advance notice. We had F3's and F4's they day before, but we were still expecting it to get bad on that day.

Thank you for expressing the importance of the human impact. Is there any way wind blown debris affects your calculations? I realize that is a hard variable to account for. Just a random thought.

[@junefirst]

Wind blown debris is definitely a factor to consider, but I don't think there's a clean way to account for it unless you know what hit the object and its velocity relative to the wind. These mathematical models that I show are very idealized and are meant to illustrate ballpark estimates based on geometries. It would be really cool to put simulations together one day that would take these things into consideration, but I would need to get very good at coding and have access to a supercomputer, haha.

[@Nefertiti0403]

Here’s My question. Is there Anything Above ground that can with stand 200-259 mph winds????

[@cheddar2648]

You made an excellent appeal to change the rating criteria, maybe not to replace the Enhanced Fujita scale, but to be used in concert with it to capture the human impact. Does the total destruction of a well built modern barn with EF-5 damage indicators really merit a ranking equal to Moore 2013? Found you on the blue bird app, was not disappointed. Thank you for this, and God Bless these victims and their families. The width of that EF0 damage field at the beginning of the track, wow.

As of today, April 4th 2024, I have a bad feeling about there being another EF5 tornado this year. I don't really watch tornado videos, but I'd say in the past 48 hours I've heard it mentioned about 5 different times from various places (TV, radio, etc) how the May 20th 2013 was the 'last' EF5 tornado. I'm telling you, when things like this happen to me it's like a weird premonition of things to come. I hope this doesn't come to fruition, but I'm telling you it's weird enough I took noticed that I heard about this tornado several times within hours of each other when I never hear about it otherwise.

People do not forget tornados, especially large tornados in cities where no one is expecting them. We had one in Edmonton, Alberta, Canada in 1987. It was Friday, July 31 when Edmonton was hit by a large, rain wrapped wedge, tornado that was rated as Ef4 in places, with a maximum wind speed just 1 mph below an Ef5. That day is now known as Black Friday and not one person who was there will ever forget exactly where they were and what they were doing on that fateful day. 27 people lost their lives - a number of whom drove their cars straight into the rain wrapped wedge, which looked nothing like the long ropey tornados they’d seen on tv. All they could see was rain and a sky as black as pitch, although nightfall was still a long 5 hours away. It is hard to imagine what it must be like to live in tornado alley, knowing the risk you are exposed to every year in tornado season. I wonder if people are constantly on the look out for those sea green clouds that seem to foretell incoming tornados. How many stay to rebuild after their towns and cities have been ripped to shreds? How many are so traumatized, they have to leave everything behind and move outside tornado alley?

[@jasonstaroscik1627]

I’ll never understand using damage as a criteria for assigning a rating. There’s too many variables that you touched on including quality of construction. Hurricanes are rated based solely on wind speed, why not tornadoes?

[@jamessimon3433]

Sweet video man very professional

[@SkullPrism]

Could the loop be a failed occlusion, much like El Reno 2013? 🤔

[@wolfywise]

I can't wait until you do a video on Smithville, imo one of the strongest tornadoes to ever impact the US.

[@AllThingsConsidered333]

Smithville was crazy! I’ve seen some excellent videos on that one…

[@Nefertiti0403]

I’ve only been in 80-100 mph winds. In Temple TX in May 2024 we had two tornados. One was EF2. I think. I know that’s nothing compared to these, BUT IT IS STILL TERRIFYING NONE THE LESS 🤢😵‍💫😵‍💫

[@bubbawubba2307]

Sounds like to me the difference between an F4 tornado IE mayfield/ rolling fork tornado vs F5 Moore is speed of the tornado going across the ground. The mayfield tornado averaged 55 mph. Going 60 mph most of the time. I saw slabbed buildings in Cayce ky with no debris from the buildings that used to be there and after leaving Cayce it sucked up topsoil up to 18 inches deep in spots The slower the tornado the more damage it will cause.

[@smoothmove7566]

It would seem that an EF 4 going through a field would not compare with an EF4 going through a residential area, I would think an EF 4 going through the area that can fill it's hands with battering rams would make it appear more powerful when it wasn't.

[@timhousley6845]

your channel is making me think of how these houses are built and that people will go cheap I think there should be investigations into these companies that build these homes what is the point of a city puting codes and requirements if no one abides by them and putting the life of American citizens at risk and yes I know an EF5 tornado is a hard thing to survive maybe with this channel people will start to see this travesty and start pushing for the political will for leaders to hold these companies accountable anyways love your channel keep up the work

[@faithsfabulousbeautybar6756]

I remember that day. I watched it on tv and with storms in the ft worth tx area too. We were aware that tornadoes were possible that day. I remember the storm in ft worth that afternoon it was erie and green. Thinking we were going to have a tornado it was actually the moore Oklahoma tornado. It was so intense. I still can't believe it to this day. We were fortunate to be missed by the tornado but that sky was never forgotten.

what website is he using

where did you get the map things

Remember sitting at the dinner table watching it live on a laptop as it was going through moore

[@LouisMacPherson-zv1jc]

There's even more to this cylinder story and the clue is in the design: It's cylindrical, a smooth surface that would have a lower drag coefficient than a multi-sided object; say a square, rectangular or hexagonal shape. However, not to appear contradictory, a multi-sided shape would have a considerably higher drag coefficient, meaning a 20,000lb square tank would not be thrown / carried as far as the cylinder, or would it? Is the amount of kinetic energy needed to move any object a specific distance amplified or mitigated by the shape of an object? In any case, the fact that a 20,000lb cylinder with a low coefficient of drag was thrown further than a mile is mind boggling. The power required to keep the perfectly smooth exterior of the cylinder elevated and within the grip of the tornadoes centrifugal force for more than a mile before jettisoning it is beyond comprehension, exponentiation notwithstanding. It's a crude rudimentary rule, but the faster any object is moving, and the heavier the object, the further distance it will travel and, I suspect, the shape of the object may not even be a factor. Would love to hear some thoughts.

[@danielwieten8617]

I wish they’d put Joplin on the DAT. I actually emailed NWS to ask why it’s not on there and they said it was because it’s only been in widespread use for the last 8-10 years and entries before then are few and far between, and I’m like…ok but nearly every other major 2011 tornado is on there?? Oh well

[@augustolobo2280]

May 2013 was definitely insane for Oklahoma, specially OKC general area. 11 days later you'd have El Reno

[@about19wookiees14]

If the houses that were rebuilt are hit again and have the same level of damage, every single one of them will be EF5. All of those houses had to be signed off on by a LICENSED city inspector, and all new constructions are required to have tornado ties in both Cleveland and Oklahoma county. Moore HS tornado shelter can fit nearly and probably over 3000 people in one wing. There’s 2 wings and 2 floors on both. It is rated for winds of 375mph, and impacts rated for equivalent of 270kg of explosives. Following proper procedures(they don’t mess around, I know first hand the drills they did, I went there) they can move the entire school population in there in under 7 minutes. If they don’t have 7 minutes(we just had an unwarned nocturnal EF3 the other day), the historic parts of the school are EF4 rated like all Moore schools, but the new additions I’ve heard are also EF4 rated steel and concrete construction. With the new codes saying you can’t have windows facing the street in schools because yay this country is amazing, there’s no windows making it *probably* able to resist anything it needs to. I graduated in ‘21, and am now pursuing a degree in architecture at OU because I want to be the reason In more ways than one why people survive these storms.

[@gmd_sussybaka6956]

Just remember that THIS was not the worst tornado damage at that time. The most EXTREME damage ever recorded was the jarrell F-5 with Est. Of 260 MPH and moved a slow, painfull 2-3 MPH and Jarrell even had more Confirmed deaths. 27, Because it was so slow it left absolutely NOTHING left in its path it barely dodged the main part of Jarrell but unfortunately hit The double creek estates area where the worst of the worst damage would occur. Houses ripped off of their foundations, All large debris that would be there. Absent. Bodies parts torn so violently investigators had no clue to who the bodies belonged to. R.I.P to all the people who died in Jarrell and moore

[@gmd_sussybaka6956]

By "at that time" i mean it's still now

[@johnf817]

You have to remember that even though the homes in Jarrell were literally gone along with the debris those tiny houses were probably built in the 50s or 70s. These homes in Moore were almost all larger modern homes built right after the May 3 1999 F5, and yet we still see complete annihilation of all structures along with anomalies like cars thrown into the air, 20,000 pound tanks thrown around like nothing etc. Jarrell is idolized somewhat, but it definitely was not as massive as Moore 2013. I'm also not sure why they are so strict and hesitant to give F5 ratings to some tornado/damages. The damage to Moore is literally widespread and inconceivable, yet it's full of F4 damage ratings. Pretty silly considering some F4 tornados that we see. Withholding the EF5 ratings so stringently, does more harm than good in my view.

[@ac7666]

11:49 Without doing any googling on the tornado, I'd say that loop looks like a failed occlusion attempt
