Greatest Pressure Drop
"However, the pressure instrument was inside a vehicle which experienced winds greater than 50 metres per second (110 mph) and therefore this measurement was likely contaminated substantially by dynamic effects."
This statement contained errors of fact and conclusion. Most importantly, the instrument was mounted outside the vehicle, not inside. The Vaisala pressure sensor was installed inside an R.M. Young static pressure head and the entire package was mounted on a mast on the vehicle's roof. The sensor was tested extensively after the event by the authors and the manufacturer and found to be in perfect working order. Therefore this could not be a cause of contamination. In fact, nowhere does the article, or any literature to follow, demonstrate the reading was "contaminated substantially." On the contrary, the article describes modeling conditions under which such a reading is possible via single cell vortex breakdown. Blair, Scott F.; D.R. Deroche, A.E. Pietrycha (2008).

Biggest single tornado: During the Super Outbreak of April 3, 1974, one tornado left a 5 mile wide damage path near Frankfort, Kentucky.
Slowest ground speed: Less than 10 mph (16 km/h) during the Central Texas tornado outbreak.
Verification
Most significant coincidence: A small town in Kansas called Codell was hit by a tornado on the exact same date three years straight! A tornado hit on May 20, 1916, 1917, and 1918. The U.S. gets 100,000 storms a year; only 1% produces a tornado. The odds of this coincidence occurring again is practically infinitesimal to nonexistent.

No fatal tornadoes in Canada during the 1990's?
The fact that Canada didn't had a killer tornado in the 1990's is not true. I checked in La Presse's archives and there has been one fatal F2 tornado in St-Charles east of Montreal in July 1994 - which killed a local doctor. The article is in French and not accessible by Internet but here's the source : M-F Leger, "Deja six tornades et l'annee n'est pas fini", June 11th 1994, La Presse, Montreal, p.A1 ---> The translation should be : "Already six tornadoes and the year is not over"-- JForget 19:06, 11 June 2006 (UTC)
Path Lengths
In accordance with the following website [3], the longest tornado path was 293 miles. A weather book I own confirms this measurement.
Maximum Winds
I edited the wind speeds to agree with the Doppler on Wheels website [4] and with the refereed publication on the Red Rock tornado. Hebrooks87 20:36, 20 June 2006 (UTC)Hebrooks87
Narrowest F5 tornado
I was wondering if anyone knows what was the "smallest" F5 tornado in width, I know I saw at a page ( [5] the Oakfield tornado was only 100 yards wide when it was an F5, although there were probably one or two that may have been smaller then that when they were AT F5 strength. -- JForget 01:04, 16 July 2006 (UTC)
Kansas May 2003 F5?
Is there a citation for the statement that one of the F4s in Kansas in May 2003 was considered to be an F5 before being rated F4? There were two F4s that month in Kansas (Crawford County and Leavenworth/Wyandotte County). I don't know the thought process of the Quick Response Team survey on Crawford County, but my office mate was on the other one that assigned the rating and no one on the team considered it an F5. It had marginal F4 damage [6]. Hebrooks87 13:02, 16 July 2006 (UTC)Hebrooks87
Umm ok why are the 80's so special?? Were there no deadly tornadoes in the 70's? Or even the 60's for that mater? DPM 21:36, 8 September 2006 (UTC)
A tornado occurring at a specific date and time doesnt seem to be much of a coincidence. I'm sure if you look hard enough you could find one at 12:34 on 5/6 of one year...it's just not that spectacular of an occurrance. Plus, it was 11:11 PM, which is 23:11 in many countries. I'm going to remove it. - Runningonbrains 22:26, 12 January 2007 (UTC)
The SPC top 10 damage table has some serious problems and shouldn't be used. For starters, it only goes back to the beginning of Storm Data. Second, the use of the central values in the damage category that were used up through 1995 creates some really odd values, given the breadth of the categories (e.g., 50 million-500 million is designated as 250 million.) This is especially troublesome given that some of the cases actually have damage amounts in the text entry in Storm Data (the paper copies, not necessarily the online approximation.) As an example of this problem, combined with another problem, the first entry, with $1,250,000,000 in 1973 dollars is the Conyers, GA tornado. In the paper version of Storm Data, the damage is given as $89M for the tornado. This gets translated using the central value as $250M, nearly tripling the damage from the reported value. In addition, for that case, the tornado hit a total of 5 counties. In the online Storm Data, each county is credited as having $250M in damage (the central value of the class). When it gets taken from the county-based description back to the total track, that results in a total of $1,250M compared to the actual reported damage from the text description of $89M, a factor of 14 overestimate. On the other hand, the Wichita Falls tornado gets underestimated since the reported damage was $400M.
This doesn't even take into account the fact that inflation-adjustment is probably not the correct adjustment to make in any event. Wealth adjustment is probably more representative. A better reference to the history of damage, starting with the historical work on collecting damage estmates done by Tom Grazulis, is Brooks and Doswell (2001), which gives both inflation and wealth adjustment numbers going back to 1890. From that, the Oklahoma City tornado is the most damaging tornado when an inflation adjustment is applied, and 11th most damaging when wealth-adjustment is applied. 1896 St. Louis, is the damaging tornado by that metric, in US history.

I changed the name of Wesley F. Unruh to Wesley P. Unruh in reference 6. I knew the man (who has recently died). However the citation is correct. The error is in the journal. Is it more appropriate to cite the correct name or the correct article? contribs) 12:31, 2 July 2008 (UTC)
Why is the Joplin tornado listed as the deadliest in Missouri history? Should the 1896 St. Louis tornado take that title with its 255 deaths versus Joplin's ~160? Or were a significant number of the St. Louis Tornado's fatalities in Illinois? TornadoLGS ( talk) 00:07, 6 January 2012 (UTC)
I took a look at thee NCDC data seems to contradict the statement that no tornadoes between 1999 and 2012 caused more than $250 million worth of damage. It would appear that the database lists county segments for individual tornadoes separately. With that in mind I looked at a few surveys and found that the F4 tornado that hit the Oklahoma city area on May 8, 2003 caused $210 million in damage Cleveland County and $160 million in Oklahoma county for a total of $370 million. The individual pages for these two segments state that they were both part of the same damage path. The details given for the two damage segments state that they were from the same tornado. I realize this doesn't put it in the top 10, but it would make the statement about tornadoes from 1999 to 2010 incorrect. TornadoLGS ( talk) 15:49, 11 January 2012 (UTC)

I want to get other opinions, but should we have a section titled, "Most documented F5/EF-5 tornadoes in one day", or even "Most documented F5/EF-5 tornadoes in one tornado outbreak"? I think the first one is probably unnessecary, as the max is probably 2-3. The most F5s tornadoes in one outbreak would probably be more noteworthy. But I'd like to get some second opinions. - 1morey July 19, 2013 3:19 PM (EST) — Preceding unsigned comment added by 1morey ( talk • contribs)

so for exceptional coincidences , i find Tuscaloosa/Birmingham should be there , a lot of F4/F5 have hit there a lot of times , and St Louis , infact ive read somewhere that i cant find now... about st Louis had it worst then Moore Oklahoma.
there are others that im unsure that should be there but i have been wondering about it... like Lazbuddie, Texas for 2 different days of having this https://www.youtube.com/watch?v=Ubuz-V4RO94 , https://www.youtube.com/watch?v=uQ0rOXM_ArE
And at southwestern Corfu there were 32 waterspouts within a hour from one storm cell... https://www.youtube.com/watch?v=V0skeowmIDw
and what about the Pilger event? or dodge city event? having multiple strong violent tornadoes all over the place at the same time.
As for tornado damage width for example there should be a graph of the largest tornadoes of over 2 + miles wide , including the noaa official path width and the disputed max width , example el reno tornado 2.6 mile wide for official and 4.2 mile wide for disputed. — Preceding unsigned comment added by Joshoctober16 ( talk • contribs) 11:47, 12 February 2019 (UTC)

It has been recently discovered that the the first tornado of the Pilger Tornado family (part of the June 16–18, 2014 outbreak), towards the end of it's life, was sling-shotted by the forming Wakefield tornado to a speed of roughly 94.6 mph, over 20 mph faster than the tri-state tornado, and held it for roughly 5-10 seconds.

1:Dow seems to use M/s alot and somtimes mentions MPH , this makes alot of confusion with 1999 2013 record , one is at 301 and the other at 302 , however its stated both were 135 M/s meaning both should be the same number , rounds up at 301.986 mph , the real info use m/s , so we should likely use this instead.
2:also on may 24 of this year if no EF5 happen , then the EF5 drought record will be broken , so if none happens before may 24 , and its may 24 come and change up this record. Joshoctober16 ( talk) 03:06, 28 April 2021 (UTC)
Hi United States Man: it strikes me as quite odd having lists (and navboxes at that) appear in sections labeled as superlatives. For example, the subsection Deadliest single tornado in world history suddenly has a navbox that lists the deadliest tornadoes in Canada (?). The U.S. navbox lists are a little more fitting, but still fall under superlative headings like Deadliest single tornado in US history and Most damaging tornado, which describe a single event, rather than a collection of events. In other words, the section headings don't describe the sections' content, or the sections' content doesn't fit the section headings. When I was reading this, I found it quite jarring and took me a bit to figure out what was going on. My solution — to move the navbox lists under a new section heading that at least attempts to describe its content — might not be the best one. Do you think there is a better way to fix this, or do you not think it a problem at all? Thanks, Brycehughes ( talk) 02:18, 3 July 2021 (UTC)
Would it be possible to change the highest speed record from the Tri-State Tornado to the 93mph record set by the Pilger EF4 in 2014? Or is what is listed the highest average speed? Theforge129 ( talk) 20:01, 7 February 2022 (UTC)
ChessEric, United States Man, TornadoLGS. I have not found any sources except ESWD for this, but a F4/T9 tornado in Germany on July 1, 1891 had a forward speed of about 300 km/h. (ESWD does not mention the forward speed, but says 20km path length in 4 minutes). Almost certainly a mistake, but ESSL's ESWD does have it listed. I went ahead and put it in the highest forward speed section and specified that Tri-State is still the highest accepted. Weird, so I ain't too sure what to do. I came across it when building the List of F4 and EF4 tornadoes. Elijahandskip ( talk) 15:54, 20 September 2022 (UTC)

As of this edit at 22:02, 24 June 2024, the Highest winds observed in a tornado section in the article accurate and complies with Wikipedia’s verifiability guidelines. The information in the section should not be altered unless it is determined present information does not pertain to the section or if new information should be added. But as of this moment, the section contains entirely verifiable information. The Weather Event Writer ( Talk Page) 22:06, 24 June 2024 (UTC)
While never observed…” Like, various meteorologists have directly stated or calculated the idea of those five tornadoes having 300+ mph winds. In your most recent reversion, you stated, “
Stop trying to spread information that cannot be testified thank you. Unless you can provide evidence as to why 300 mph should be deserved other than the subjective opinion of individuals like Grazulis then you cannot pass it off as fact.”
So lately we've been talking a lot about entries in the 300 mph club for tornadoes. One entry I notice that currently isn't included is the 1995 Pampa, Texas tornado. While I myself have not seen the source, my understanding is that Grazulis estimated wind speeds at >300 mph based on photogrammetry in his elusive F5-F6 Tornadoes book. If anyone here can check an appropriate source to verify, I think it should be mentioned. TornadoLGS ( talk) 01:39, 25 June 2024 (UTC)
Hey @ MarioProtIV: — What source says Greenfield had confirmed 313.5 mph winds? I had been reverting that so much during the massive edit war yesterday as original research.

There appears to be an ongoing gag on a subreddit called r/EF5 where users change information about the Moore-Bridge Creek and Greenfield tornadoes in an attempt to make one "win" over the other, or something like that.

Ok. Since the edit war finally subsided, let's have a nice, calm discussion, with no reversions or changes until we have a community consensus, for how to manage the three tornadoes and the new University of Illinois publication ( seen here).

The publication states, "Wurman et al. 2007 originally reported 302 mph in the Bridgecreek, Oklahoma, 3 May 1999 tornado. This was subsequently revised upwards in Wurman et al. 2021, to 321 mph, using improved techniques.
"
The publication states, "Wurman et al. 2014 reported 291-336 mph and Bluestein et al. 2015 reported 313 mph in extremely small extremely rapidly moving sub-tornado scale vortices in the El Reno, Oklahoma 31 May 2013 tornado.
"
115–150 m s-1 at or below 100 m ARL on 31 May 2013 at El Reno, Oklahoma (Wurman et al. 2014a; Bluestein et al. 2018).”
The publication states, "The DOW directly measured Doppler velocities as high as 263-271 mph (118-121 m/s). DOW measurements are used to calculate peak tornado wind speeds using methods described in Wurman et al (2021a) and an upcoming American Society of Civil Engineering (ASCE) formal standard for determining tornado wind speeds from proximate radar measurements. DOW scientists calculate peak ground-relative wind speeds, in a very narrow swath to the immediate east of the path of the center of the tornado circulation, as high as 309-318 mph (138-142 m/s).
"
For less than a second, the researchers calculated wind speeds of more than 300 mph in a portion of the tornado."
Hey Dovah12333, let’s not get into an edit war over the section. Let’s instead discuss it here and come to a community consensus. If I may ask, why do you think the information should be removed from the article? The Weather Event Writer ( Talk Page) 16:15, 29 June 2024 (UTC)
The article for the 1997 Jarrell tornado had it with 300mph winds, as multiple sources claimed, but I couldn't find any reliable academic literature and all the sources that existed seemed faulty (see the talk page there). Also, I've seen online that the 1953 Worcester tornado may have had winds in excess of 300mph, up to 327mph, but I haven't checked all the sources. I assume Grazulis (who has a close connection to Worcester specifically) made that claim, so if anyone can check that, I'll be sure to add it to the article. GeorgeMemulous ( talk) 17:08, 19 July 2024 (UTC)
May 19, 2024's Custer County tornado was nearly 3 miles wide if we're counting the entire width of EF0 damage. On the Damage Assessment Toolkit, all 3 miles (nearly, I measured 2.75) are considered tornadic damage instead of wind damage. Also, Hallam, NE's 2.4 mile tornado and Timber Lake's supposed 4 mile tornado were assessed via damage paths (Timber Lake specifically doesn't call the 4-mile measurement a tornado, instead saying "tornadic wind"). It's not necessarily easy to differentiate between strong, EF0-intensity rear-flank downdraft and inflow winds from direct tornadic winds... but, at the same time, what is the difference? Hallam and Timber Lake were assessed from damage paths, so I added Custer County 2024 in the largest width section on account of its damage path, even if it was only 1 mile wide, based on the assessment from NOAA on the Damage Assessment Toolkit and the PNS from Norman.

No fatal tornadoes in Canada during the 1990's?
The fact that Canada didn't had a killer tornado in the 1990's is not true. I checked in La Presse's archives and there has been one fatal F2 tornado in St-Charles east of Montreal in July 1994 - which killed a local doctor. The article is in French and not accessible by Internet but here's the source : M-F Leger, "Deja six tornades et l'annee n'est pas fini", June 11th 1994, La Presse, Montreal, p.A1 ---> The translation should be : "Already six tornadoes and the year is not over"-- JForget 19:06, 11 June 2006 (UTC)
Path Lengths
In accordance with the following website [3], the longest tornado path was 293 miles. A weather book I own confirms this measurement.
Maximum Winds
I edited the wind speeds to agree with the Doppler on Wheels website [4] and with the refereed publication on the Red Rock tornado. Hebrooks87 20:36, 20 June 2006 (UTC)Hebrooks87
Narrowest F5 tornado
I was wondering if anyone knows what was the "smallest" F5 tornado in width, I know I saw at a page ( [5] the Oakfield tornado was only 100 yards wide when it was an F5, although there were probably one or two that may have been smaller then that when they were AT F5 strength. -- JForget 01:04, 16 July 2006 (UTC)
Kansas May 2003 F5?
Is there a citation for the statement that one of the F4s in Kansas in May 2003 was considered to be an F5 before being rated F4? There were two F4s that month in Kansas (Crawford County and Leavenworth/Wyandotte County). I don't know the thought process of the Quick Response Team survey on Crawford County, but my office mate was on the other one that assigned the rating and no one on the team considered it an F5. It had marginal F4 damage [6]. Hebrooks87 13:02, 16 July 2006 (UTC)Hebrooks87
Umm ok why are the 80's so special?? Were there no deadly tornadoes in the 70's? Or even the 60's for that mater? DPM 21:36, 8 September 2006 (UTC)
A tornado occurring at a specific date and time doesnt seem to be much of a coincidence. I'm sure if you look hard enough you could find one at 12:34 on 5/6 of one year...it's just not that spectacular of an occurrance. Plus, it was 11:11 PM, which is 23:11 in many countries. I'm going to remove it. - Runningonbrains 22:26, 12 January 2007 (UTC)
The SPC top 10 damage table has some serious problems and shouldn't be used. For starters, it only goes back to the beginning of Storm Data. Second, the use of the central values in the damage category that were used up through 1995 creates some really odd values, given the breadth of the categories (e.g., 50 million-500 million is designated as 250 million.) This is especially troublesome given that some of the cases actually have damage amounts in the text entry in Storm Data (the paper copies, not necessarily the online approximation.) As an example of this problem, combined with another problem, the first entry, with $1,250,000,000 in 1973 dollars is the Conyers, GA tornado. In the paper version of Storm Data, the damage is given as $89M for the tornado. This gets translated using the central value as $250M, nearly tripling the damage from the reported value. In addition, for that case, the tornado hit a total of 5 counties. In the online Storm Data, each county is credited as having $250M in damage (the central value of the class). When it gets taken from the county-based description back to the total track, that results in a total of $1,250M compared to the actual reported damage from the text description of $89M, a factor of 14 overestimate. On the other hand, the Wichita Falls tornado gets underestimated since the reported damage was $400M.
This doesn't even take into account the fact that inflation-adjustment is probably not the correct adjustment to make in any event. Wealth adjustment is probably more representative. A better reference to the history of damage, starting with the historical work on collecting damage estmates done by Tom Grazulis, is Brooks and Doswell (2001), which gives both inflation and wealth adjustment numbers going back to 1890. From that, the Oklahoma City tornado is the most damaging tornado when an inflation adjustment is applied, and 11th most damaging when wealth-adjustment is applied. 1896 St. Louis, is the damaging tornado by that metric, in US history.

I changed the name of Wesley F. Unruh to Wesley P. Unruh in reference 6. I knew the man (who has recently died). However the citation is correct. The error is in the journal. Is it more appropriate to cite the correct name or the correct article? contribs) 12:31, 2 July 2008 (UTC)
Why is the Joplin tornado listed as the deadliest in Missouri history? Should the 1896 St. Louis tornado take that title with its 255 deaths versus Joplin's ~160? Or were a significant number of the St. Louis Tornado's fatalities in Illinois? TornadoLGS ( talk) 00:07, 6 January 2012 (UTC)
I took a look at thee NCDC data seems to contradict the statement that no tornadoes between 1999 and 2012 caused more than $250 million worth of damage. It would appear that the database lists county segments for individual tornadoes separately. With that in mind I looked at a few surveys and found that the F4 tornado that hit the Oklahoma city area on May 8, 2003 caused $210 million in damage Cleveland County and $160 million in Oklahoma county for a total of $370 million. The individual pages for these two segments state that they were both part of the same damage path. The details given for the two damage segments state that they were from the same tornado. I realize this doesn't put it in the top 10, but it would make the statement about tornadoes from 1999 to 2010 incorrect. TornadoLGS ( talk) 15:49, 11 January 2012 (UTC)

I want to get other opinions, but should we have a section titled, "Most documented F5/EF-5 tornadoes in one day", or even "Most documented F5/EF-5 tornadoes in one tornado outbreak"? I think the first one is probably unnessecary, as the max is probably 2-3. The most F5s tornadoes in one outbreak would probably be more noteworthy.

so for exceptional coincidences , i find Tuscaloosa/Birmingham should be there , a lot of F4/F5 have hit there a lot of times , and St Louis , infact ive read somewhere that i cant find now... about st Louis had it worst then Moore Oklahoma.
there are others that im unsure that should be there but i have been wondering about it... like Lazbuddie, Texas for 2 different days of having this https://www.youtube.com/watch?v=Ubuz-V4RO94 , https://www.youtube.com/watch?v=uQ0rOXM_ArE
And at southwestern Corfu there were 32 waterspouts within a hour from one storm cell... https://www.youtube.com/watch?v=V0skeowmIDw
and what about the Pilger event? or dodge city event? having multiple strong violent tornadoes all over the place at the same time.
As for tornado damage width for example there should be a graph of the largest tornadoes of over 2 + miles wide , including the noaa official path width and the disputed max width , example el reno tornado 2.6 mile wide for official and 4.2 mile wide for disputed. — Preceding unsigned comment added by Joshoctober16 ( talk • contribs) 11:47, 12 February 2019 (UTC)

It has been recently discovered that the the first tornado of the Pilger Tornado family (part of the June 16–18, 2014 outbreak), towards the end of it's life, was sling-shotted by the forming Wakefield tornado to a speed of roughly 94.6 mph, over 20 mph faster than the tri-state tornado, and held it for roughly 5-10 seconds.

1:Dow seems to use M/s alot and somtimes mentions MPH , this makes alot of confusion with 1999 2013 record , one is at 301 and the other at 302 , however its stated both were 135 M/s meaning both should be the same number , rounds up at 301.986 mph , the real info use m/s , so we should likely use this instead.
2:also on may 24 of this year if no EF5 happen , then the EF5 drought record will be broken , so if none happens before may 24 , and its may 24 come and change up this record. Joshoctober16 ( talk) 03:06, 28 April 2021 (UTC)
Hi United States Man: it strikes me as quite odd having lists (and navboxes at that) appear in sections labeled as superlatives. For example, the subsection Deadliest single tornado in world history suddenly has a navbox that lists the deadliest tornadoes in Canada (?). The U.S. navbox lists are a little more fitting, but still fall under superlative headings like Deadliest single tornado in US history and Most damaging tornado, which describe a single event, rather than a collection of events. In other words, the section headings don't describe the sections' content, or the sections' content doesn't fit the section headings. When I was reading this, I found it quite jarring and took me a bit to figure out what was going on. My solution — to move the navbox lists under a new section heading that at least attempts to describe its content — might not be the best one. Do you think there is a better way to fix this, or do you not think it a problem at all? Thanks, Brycehughes ( talk) 02:18, 3 July 2021 (UTC)
Would it be possible to change the highest speed record from the Tri-State Tornado to the 93mph record set by the Pilger EF4 in 2014? Or is what is listed the highest average speed? Theforge129 ( talk) 20:01, 7 February 2022 (UTC)
ChessEric, United States Man, TornadoLGS. I have not found any sources except ESWD for this, but a F4/T9 tornado in Germany on July 1, 1891 had a forward speed of about 300 km/h. (ESWD does not mention the forward speed, but says 20km path length in 4 minutes). Almost certainly a mistake, but ESSL's ESWD does have it listed. I went ahead and put it in the highest forward speed section and specified that Tri-State is still the highest accepted. Weird, so I ain't too sure what to do. I came across it when building the List of F4 and EF4 tornadoes. Elijahandskip ( talk) 15:54, 20 September 2022 (UTC)

As of this edit at 22:02, 24 June 2024, the Highest winds observed in a tornado section in the article accurate and complies with Wikipedia’s verifiability guidelines. The information in the section should not be altered unless it is determined present information does not pertain to the section or if new information should be added. But as of this moment, the section contains entirely verifiable information. The Weather Event Writer ( Talk Page) 22:06, 24 June 2024 (UTC)
While never observed…” Like, various meteorologists have directly stated or calculated the idea of those five tornadoes having 300+ mph winds. In your most recent reversion, you stated, “
Stop trying to spread information that cannot be testified thank you. Unless you can provide evidence as to why 300 mph should be deserved other than the subjective opinion of individuals like Grazulis then you cannot pass it off as fact.”
So lately we've been talking a lot about entries in the 300 mph club for tornadoes. One entry I notice that currently isn't included is the 1995 Pampa, Texas tornado. While I myself have not seen the source, my understanding is that Grazulis estimated wind speeds at >300 mph based on photogrammetry in his elusive F5-F6 Tornadoes book. If anyone here can check an appropriate source to verify, I think it should be mentioned. TornadoLGS ( talk) 01:39, 25 June 2024 (UTC)
Hey @ MarioProtIV: — What source says Greenfield had confirmed 313.5 mph winds? I had been reverting that so much during the massive edit war yesterday as original research.

There appears to be an ongoing gag on a subreddit called r/EF5 where users change information about the Moore-Bridge Creek and Greenfield tornadoes in an attempt to make one "win" over the other, or something like that.

The publication states, "Wurman et al. 2007 originally reported 302 mph in the Bridgecreek, Oklahoma, 3 May 1999 tornado. This was subsequently revised upwards in Wurman et al. 2021, to 321 mph, using improved techniques.
"
The publication states, "Wurman et al. 2014 reported 291-336 mph and Bluestein et al. 2015 reported 313 mph in extremely small extremely rapidly moving sub-tornado scale vortices in the El Reno, Oklahoma 31 May 2013 tornado.
"
115–150 m s-1 at or below 100 m ARL on 31 May 2013 at El Reno, Oklahoma (Wurman et al. 2014a; Bluestein et al. 2018).”
The publication states, "The DOW directly measured Doppler velocities as high as 263-271 mph (118-121 m/s). DOW measurements are used to calculate peak tornado wind speeds using methods described in Wurman et al (2021a) and an upcoming American Society of Civil Engineering (ASCE) formal standard for determining tornado wind speeds from proximate radar measurements. DOW scientists calculate peak ground-relative wind speeds, in a very narrow swath to the immediate east of the path of the center of the tornado circulation, as high as 309-318 mph (138-142 m/s).
"
For less than a second, the researchers calculated wind speeds of more than 300 mph in a portion of the tornado."
Hey Dovah12333, let’s not get into an edit war over the section. Let’s instead discuss it here and come to a community consensus. If I may ask, why do you think the information should be removed from the article? The Weather Event Writer ( Talk Page) 16:15, 29 June 2024 (UTC)
The article for the 1997 Jarrell tornado had it with 300mph winds, as multiple sources claimed, but I couldn't find any reliable academic literature and all the sources that existed seemed faulty (see the talk page there). Also, I've seen online that the 1953 Worcester tornado may have had winds in excess of 300mph, up to 327mph, but I haven't checked all the sources. I assume Grazulis (who has a close connection to Worcester specifically) made that claim, so if anyone can check that, I'll be sure to add it to the article. GeorgeMemulous ( talk) 17:08, 19 July 2024 (UTC)
May 19, 2024's Custer County tornado was nearly 3 miles wide if we're counting the entire width of EF0 damage. On the Damage Assessment Toolkit, all 3 miles (nearly, I measured 2.75) are considered tornadic damage instead of wind damage. Also, Hallam, NE's 2.4 mile tornado and Timber Lake's supposed 4 mile tornado were assessed via damage paths (Timber Lake specifically doesn't call the 4-mile measurement a tornado, instead saying "tornadic wind"). It's not necessarily easy to differentiate between strong, EF0-intensity rear-flank downdraft and inflow winds from direct tornadic winds... but, at the same time, what is the difference? Hallam and Timber Lake were assessed from damage paths, so I added Custer County 2024 in the largest width section on account of its damage path, even if it was only 1 mile wide, based on the assessment from NOAA on the Damage Assessment Toolkit and the PNS from Norman.
