El Reno tornado incident Q & A

Important Message 30 Years of Storm Chasing & Photography Dan's YouTube Video Channel Dan's Twitter feed Dan's RSS/XML feed

With high-profile articles on the El Reno tornado coming out soon, I wanted to post my detailed answers and clarifications to some common questions I have received.

Do you have more information on the El Reno tornado?

I have attempted to publicly post every detail I can regarding this tornado and my encounter, including GPS logs, videos and images. The following are links to everything I have available currently:

What caused your vehicle's difficulty maintaining speed on Reuter Road?
The short answer is the combination of a.) strong headwinds, b.) the gravel road and c.) traction control. Traction control is an automatic feature of most newer cars, designed to prevent wheel slip that can lead to a loss of control at higher speeds. It detects when a car's tires are beginning to slip under power, then automatically cuts power to the wheels until the tires regain grip. Wheel slip happens all the time when you drive in snow and ice: you hit the gas a little too hard, and your wheels break traction and spin. This can also happen in the rain or on loose gravel.

If you've ever driven a car with traction control in ice and snow, you know that sometimes you have to manually turn it off so the wheels can spin a little and keep you moving. Otherwise, the traction control will not allow the wheels to spin, and you'll just stop moving altogether. This happened to me in a snowstorm last winter from just going up a slight incline into a McDonald's parking lot. My wheels needed to spin a little to keep me moving up the slight gradient, but traction control wouldn't allow it, and I came to a stop despite pressing on the gas. I had to back up, turn off traction control (via a manual override button) and make another run at it.

My car's traction control was continuously kicking in during the escape from the El Reno tornado. Due to the combination of strong headwinds and the gravel road, the wheels were slipping, causing traction control to cut power to the wheels. This limited my speed to a maximum of 43mph. My car's manual override button for the traction control does not work over a speed of 30-35mph, so I could not deactivate it despite repeatedly pressing the button.

Why were you driving such a small, lightweight car?

My Toyota Yaris is my 'daily driver' car. I bought it because gas prices are high, and the Yaris gets nearly 40mpg on the highway. Ideally, I would prefer to chase in a larger vehicle, but it is just not possible for me currently. Like most storm chasers, I have to pay for all of my photography expenses out of pocket, the largest of which is fuel. Contrary to myths, most storm chasers aren't paid to chase aside from occasional video sales. Revenue from the video I sell typically doesn't cover all of my expenses incurred when chasing tornadoes in the spring. As such, I can't afford to have a second dedicated chase vehicle, nor can I afford to pay for the fuel required to drive a larger vehicle the long distances typical of a chase season.
Why did you choose the route you did? Were you trying to get close?
I was not trying to get close. I knew from how the tornado first appeared that it would be very large, violent and dangerous. My goal was simply to remain in a good position for photography and video, which I felt would be best with the tornado backlit by the bright skies to the southwest. I wanted to be just close enough to have a high-contrast view.

My plan was to roughly parallel the tornado to its north as it moved east, while staying slightly ahead of it (to its northeast). I moved the additional mile south (closer to it) at Choctaw because of the tornado's initial rapid movement southward away from me. I expected the tornado to either continue moving east-southeast or eastward, which is why I kept going east on Reuter Road (NW 10th). I saw no reason to go north at Highway 81 because I didn't yet realize the tornado had turned.

I didn't recognize the dramatic change in its track until it was nearly upon me on Reuter west of Highway 81. This is because while the tornado was making its drastic north turn and widening at Highway 81, it was completely wrapped in heavy rain, masking from my vantage point what it was really doing. It is common for a relatively benign area of precipitation to wrap around a tornado when it becomes "rain wrapped", so the proximity of this area of rain itself was not initially a major concern. As I realized later, this area of rain *was* the tornado itself - IE, the outer boundary of tornadic wind speeds completely encompassed the rain. As the area of rain approached Reuter, I could finally begin to see how fast the rain curtains were moving and realized they were embedded in tornadic winds. This area of rain rapidly condensed into the large wedge tornado visible in my rear-facing camera once I cleared Evans Road.

Below is a map I put together that shows my path, the tornado's path, and what I *thought* the tornado was doing and was going to do in the future. As you can see, if the tornado had moved like I expected (more easterly), I would have remained at a safe viewing angle on Reuter Road. (Click on this map to view a larger version):

Why did you stop after escaping the tornado?
I stopped when I exited the heavy rain curtains and I could see that I was out of the tornado's path. I'm a storm chaser, so I wanted to see the tornado and get pictures and video of it. Every spring, I drive thousands of miles and spend thousands of dollars to get to tornadoes, so I won't drive away once I catch one.
Why did you get out of your car?
Again, I'm a storm chaser, so I wanted to see the tornado and get pictures and video of it. My mistake with El Reno was underestimating the wind fields surrounding the visible condensation funnel of a tornado of such magnitude. According to mobile doppler radars, I was still inside the primary tornado circulation when I got out of my car. I was not aware of this at the time. While tornadic winds often extend out some distance from a tornado's visible funnel, the El Reno tornado was remarkably strong and broad in this regard.

Either way, I should have taken into consideration the likelihood of at least violent RFD (rear-flank downdraft) winds wrapping around the back side of such an obviously powerful tornado. In retrospect, I should have stayed in the car and moved farther east and south before trying to get more video and pictures.

I am not a risk-taker and have no desire to get hurt or damage my car. Regularly doing so would make storm chasing more expensive than it already is, and unaffordable for me. Not to mention the fact that damage and injuries ends a chase on the spot, and potentially puts me out of commission for additional storm chase days. I paid for the damage to my car and equipment out of my own pocket and did not file an insurance claim.

Did you see the Twistex vehicle?
I did not see their vehicle during the event. I did not learn that I had been on the same road until 3 days later, after I had arrived home. I then discovered that the rear-facing dash camera I installed in my car had captured the images.
Was chaser traffic a factor in this incident?
Chaser traffic was not a factor in this incident. When the Twistex vehicle and I crossed Highway 81, there were no other cars ahead or behind us for at least a mile in front and 1/2 mile behind. There were no vehicles on Highway 81 in either northbound or southbound lanes. Police had the southbound lanes blocked to our north, and the tornado was crossing the road to the south, blocking the northbound lanes.
Is there more video from the rear-facing camera?
This is the most frequent question I have received. Yes, the rear-facing dash camera was recording during the entire event. What it captured is not graphic, but it does show the sequence of events that transpired. I have elected to keep this part of the footage private out of respect to the families affected by the tragedy. The footage from the rear camera in its entirety may be released at a future time. Until then, it is being kept strictly private.

For media interests reading this: due to some disconcerting behavior by those seeking out this footage for commerical interests, I've set up some ground rules regarding this footage:

  1. The families are not to be contacted regarding this footage, I (Dan Robinson) am the copyright holder, I am the sole contact, and I am the only one who can authorize a license for its use or broadcast anywhere.
  2. Any individual, group, company or filmmaker who contacts the families in disregard for this stipulation (seeking to persuade the families to allow its release) will be permanently disqualified from receiving a license for its use, even if the time comes that the families approve its release*.
  3. All of my El Reno footage has been registered with the US Copyright Office. If any of the footage is released/broadcast/used without authorization, I will, to put it lightly, go 'nuclear' with the most aggressive Federal copyright infringement lawsuit possible.
To put it another way, please respect the families and leave them alone about my car's rear camera video. You are free to contact me with any questions about the video at any time.
Did you know Tim, Paul and Carl?
Although I was not close friends with Tim, Paul or Carl, I have been mutually acquainted with Tim for many years, particularly via internet discussions. I have only met him in person a few times, most frequently at the Denver Storm Chasing & Photography conventions. We have been members of several storm chasing discussion groups through the years, and were friends on Facebook. I have always been primarily a lightning photographer, an interest that Tim and I shared. His work with high-speed lightning video was of particular interest and admiration by me.
Will El Reno change how you go?
In some cases, yes. I will no longer attempt intercepts of large or rain-wrapped tornadoes within 2 miles. There is no benefit to being close to a large wedge tornado that can even come close to balancing the risks. My strategy for very volatile-parameter days will also be less agressive and less close-range.

Having said all of that, we have to keep this event, while certainly tragic and a 'wake up call' to storm chasing, in proper perspective. This was the first such incident in the history of storm chasing, an activity that is 50 years old. The El Reno tornado was exceptionally rare in many respects, fooling many experienced and veteran storm chasers. Tragic incidents happen on a regular basis in sports such as whitewater rafting, mountain climbing, skiing and skydiving - all activities that pose much greater risks than storm chasing, yet few would advocate curtailing or ceasing participation in any of those sports as a result. The rational thing to do is learn from the tragedies so as to continue to enjoy the activities with an even greater degree of safety.

So, El Reno will certainly change how I approach large and low-visibility tornadoes. But when such opportunities present themselves, I will continue to make reasonably close approaches to the smaller, slow-moving highly-visible tornadoes - a maneuver which is generally very safe if done with proper attention to road options and storm behavior.

What is your opinion on the official rating of the El Reno tornado?
This tornado was unquestionably an EF-5 tornado, with EF-5 winds measured by two independent mobile doppler radar units. The EF-3 rating was a beaurocratic decision by NWS management that will eventually be revised. The top tornado scientists in the world today (like Dr. Howie Bluestien and Dr. Chuck Doswell) strongly disagree with the NWS decision. I went into this controversy in more detail in another blog post.

Please let me know if you have additional questions, and I will do my best to answer them on this page. All of the other information and data I have on the El Reno tornado is posted on the main expedition account page for the event.

Hello dan, I wanted to ask respectfully if the rear dash video is going to be released ? Hope you are doing very well. Thanks :)

Hi Seth, I added some more information to that section of the FAQ. Currently there are no plans to release that footage.

Thanks dan, be safe during the upcoming tornado season

Is the reason that you're not releasing the rear video because there's footage of Samaras' vehicle coming in direct contact with the tornado? I'm an admirer of your work, and I've seen screen grabs of their vehicle in the National Geographic issue that chronicles the El Reno tornado.

Good information. And I think Dan's decision to hold back the rear-facing camera footage is highly moral and respectful to the families of the Twistex team. The still frame in the National Geographic article by itself comes across as a heartbreaking portrait of the team's losing struggle before being overtaken. Dan himself is lucky to be alive! Storm photographer Skip Talbot has already put together a highly informative YouTube video, Safety Lessons From El Reno. ...Safe chases to you, Dan, and to all.

I think that a lot of people would gladly support any crowd-sourcing efforts that you might initiate for the purpose of enabling yourself to case in a safer vehicle.

Hi Dan - your YouTube footage of barely outracing the storm is chilling, even 18+ months later. Quick question about your thought process, if you can recall - did you ever consider turning north on 81 when you got to that intersection, instead of continuing east? Looking at the National Geographic still photo from your rear camera, it looks like the Cobalt was right on your tail approaching that intersection. Just curious if you were seeing satellite tornadoes or something ominous to the north that prevented you from heading that way. Thanks and stay safe!!!

Tom, thanks for posting the question. I've received that question several times, so I added an entry to this FAQ to address that. I also included a map. Let me know if you have any other questions.
- Posted by Dan R. from New Baden, IL

Dan - thanks much for the very detailed explanation and map. I think it would also be very useful to add time stamps along (1) your trip path and (2) the track of the tornado, so everyone can see how crazy close your paths came to crossing. Watching the YouTube video again, it seems to me that at ~3:30 (just before Alfadale Rd.), you were actually caught up in the outer bands of the tornado and the race was on. Would you agree? Again, I greatly appreciate you taking the time to continue to answer questions so long after and help us all understand.

Dan, if you dont mind me asking, and at first it may seem cold but here me out please... why are you not releasing that footage Of the few second, an/or rear cam at all before 6:22??? I'm sure like a lot of other people, I'm studying this(im not interested in seeing death, rather the study of what really happened or what can, did, or will). I found a great detailed write up of what happened,(from NatGeo) don't know who wrote it, how they got that info, or the video from the twistex car to quote from, but id like to see them both. (Seems to me you wouldnt see much)... What i mean is, you wouldnt see them, dying or whatever in those few seconds anyways. Its more so implied isnt it?? mainly cause its now known what happened to them 3 min after the lights disappear from your rear view At 6:21.. (so im told and read, obviously i haven't seen it) My point is you cant, and dont see them die at this point so why not release it. Ive seen bits of footage of their car at I-81 right behind you at 6:19, and quotes from tim at same time saying "go east", then around 6:20 saying something to the effect of "keep going, this is a bad spot at Alfadale rd camera clicks off) The footage you show behind you in this cut video starts at 6:22(im guessing cause you dont want to show the headlights disappearing on the unreleased video) but from eveything ive read and studied.. they got hit at 6:23.32 by then you had your rear cam going for 2 min... you stopped your car past Evans, and you cant see anything but that huge beast... So why unrelease the twistex cars headlights disappearing in the rain wrap vortex at 6:21???? If all is correct they didnt die till 2 maybe 3 min later while you where stopped, and filming. (that footage is there), they are dying, and you cant see it can you. Why cut a part that shows no death???? The lights disappearing wasn't them getting sucked into the tornado, but rather when they pulled off, crashed, or tried to deploy at the creek as you kept driving, henz why the lights disappear. You then made it to Evans Street safe(thank god btw), and recorded by hand outside. Thats when they got hit...thats when you would have seen them get enveloped by the tornado... if at all. They would have been a mile and 1/4 behind you at that point, stuck in a ditch or what ever happened. Yes its sad but with no death actually showen I don't really see the difference between the few seconds of unreleased and the rest of this video... its all hard to watch no matter what, but to cut a part that doesnt even show death seems odd to me... can you clarify???? Not showing the twistex teams car video is understandable and I wouldn't expect to see that for a very long time if ever. I read the quotes from someone who has seen it and the camera clicks off before they get hit by it so nothing bad really besides respecting them and knowing they die minutes after. Please id really like to know the real facts not bs from online bad reporting or rumors, i dont wanna be wrong, so your the man to ask!!
- Posted by Glenn Johnson from Omaha NE

to clarify I must add I did read your frequently asked questions about this topic, and I respect you're not wanting to release it because of the heartbreaking footage, in respect to the families but again as I stated above this is not the moment in which they died, you're filming the moment in which they supposedly died and that's not cut, so why cut it where you did...??? know what i mean???
- Posted by Glenn Johnson from Omaha NE

Glenn, the footage of the tornado at the moment they were struck was released that night, before anyone knew what had happened. Once I knew that the rear camera captured the Twistex car, I gave the families control over what would be released that hadn't already been. It was their wish to not release anything showing the car (with the exception of what was printed in the magazine and in Gabe Garfield's talk), and I am abiding by that out of respect and deference to them.
