El Reno Tornado Rated EF5, Widest on Record. 295mph sub-vortices winds.

That was a nasty storm. This was the storm that took a sharp turn south, catching many off guard. It is also the same storm that killed the three storm chasers.


http://www.wunderground.com/news/el-reno-oklahoma-city-tornadoes-recap-20130601


The massive tornado contained several powerful "subvortices," areas of extremely rapid rotation that swirled within the larger tornadic circulation. These subvortices contained the strongest wind speeds measured within the tornado, greater than 295 miles per hour in several different instances -- well above the 201-mph minimum requirement for a EF5 designation.

Not only did these subvortices contain almost unfathomable winds, but they were moving forward at incredible speeds, making them impossible to outrun.

"Think of the average size of an Oklahoma tornado you'd see on a typical afternoon - three or four of those things moving along the ground at a speed of 170 to 180 miles per hour, crossing each other with all kinds of violent motions going on," Smith remarked. "So this is going to be studied for a long time."

Smith later noted that a few of these vortices may have been moving along the ground at a jaw-dropping forward speed of 185 miles per hour, even as the parent tornado lumbered along at a forward speed of about 24 miles per hour.

Back when I was a youngin' I served as a storm spotter with the county civil defense. I've seen a lot of tornadoes and studied storms as a hobby most of my life, and I can't recall a tornado like this one. It is one odd duck. Structure, path,development, size.... it really stands out as different. It was one wicked monster

Spent decades as a weather reporter and historian next door in Texas. Once survived an F-5 with a carousel of twisters, and you are right about this one in OK. We have a new player in the wind.

" ... basically, the whole bottom of the cell eventually organized into one large area of strong circulation, one big assed tornado hanging there and spitting out all kinds of crazy vortices. In addition to the vortices that show up well in the numerous videos, there were a lot that aren't so apparent on film.... wild, violent horizontal circulations like I've never seen before. The inflow was crazy, I was sitting about 3 miles away and it was rocking the shit out of my truck, easily 70+ kts inflow. When it started getting rain wrapped, I got the hell out of there while I had the chance, it was growing exponentially and wasn't tracking anywhere near straight, I wasn't going to hang around tempt fate."

as their winds at ground level slow down, while the winds near the top keep their momentum. Data from 2004 show this tendency seems to have increased. Residents of hurricane-stricken areas should prepare for the eventuality of tornadoes.

10. Hurricane Barbara and the OK tornado
Wed Jun 5, 2013, 07:28 AM

Some weather observers around Texas were keeping a close eye on Pacific Hurricane Barbara as her remnants moved into the Bay of Campeche, and the satellite images suggested some of her energy may have converged with the system that produced the most recent OK tornado. I guess we'll know more when the monthly NOAA bulletins come out. In the meantime, I am wondering if Barbara's remnants are also contributing to the depression trying to swirl up in Gulf right now.

Good link, by the way. Bad news but better to know now. Thanks.

at first it was called a F4 but then after the destruction ...it was realized it was an F5 but look at the speed 295....why not call it a 300mph or 305 because it would be off the Fujita Scale ....I believe it was an F6 something that was not natural by any means


Nature seems to be going extreme

the weather channel needs to REPORT correctly...they have been underreporting the wind speeds because this was off the scale and the scale needs to be revised ....due to climate change F6 and F7 need to be included

24. Good old T.T. Fujita!

That man was a stitch. Years ago when I was an undergrad at The University of Chicago I took a class in meteorology. The last week of class our professor got some guest lecturers to come in and talk to us. One of them was Dr. T.T. Fujita. He later studied microdownbursts but at the time was still doing tornados - multi-vortex tornados were his big interest. So, anyway, T.T. comes in and gives a good lecture on tornados with cool slides and stores. At that point in his career he had not actually seen a tornado on the ground and his vanity license plate read Twister 0. A few years later he saw one and changed the plate to Twister 1. T.T. was born in Japan and immigrated to the US at an age where although he spoke English well, he still had an accent. I can still see and hear him in my mind's eye: "You think tornados don't crimb mountains - rook!" as he flashed a photo of a tornado path up one side of a mountain and down the other side. And "You think tornados don't closs water - rook!" as he showed us a photo of a tornado path on either side of a small river. He finished his lecture by saying: "Now it is tornado season here in midwest. If you are out dliving and see a tornado, you pull over to side of the load, you stop cah, you get out of cah and take photos of tornado. You send those photos to me, Dr. T.T. Fujita here at Univehsity of Chicago. Then you get back in cah and dlive rike herh*."


* I can't figure out a way to accurately transcribe how Dr. Fujita pronounced "hell". I'm sure a linguistics person could, but I'm an Ancient Near Eastern History and Culture major. However, we all knew what he meant. We did get a laugh from his "send me the photos and then get out of there', as if wherever you stopped your car, a photo developer and a post office would be directly available.
