Talk:List of derecho events

Untitled
The April 4, 2011 derecho needs to be listed AND needs an article... among the largest wind event in American history. —Preceding unsigned comment added by 64.50.95.2 (talk) 02:38, 7 April 2011 (UTC)

The 2 April 2006 tornado outbreak seems to be notable more for its tornadoes rather than any derecho. I suggest removing it from this list and will do so unless someone objects. --Globe199 17:05, 13 June 2006 (UTC)

I looked at this article yesterday and wondered about it. Only reason I left it here was the word 'derecho' buried down in the text. Maybe someone has more facts about this. Thanks Hmains 01:24, 18 July 2006 (UTC)

Will the July 17 event in Northeastern Ontario require a seperate page, or will just throw it on the list without creating a article? Lots of significant damage, tree blowdowns, major power outage in Subdury and North Bay (and will wait for Ottawa, although it does loss some caracteristics)--JForget 23:47, 17 July 2006 (UTC)

Please feel free to discuss whether or not the August 1 Southern Quebec storms should be classified as a derecho. I haven't track the whole storm so I have missed some parts of it and could have been a difference whether or not it was a derecho or not.--JForget 20:36, 2 August 2006 (UTC)

"Alabama Derecho 2009"
I've removed this entry from the list temporarily; it's not that I don't think it's notable--any derecho event that reportedly wipes out an entire town is certainly notable!--but more that there's not yet been time for reliable sources to fully report on it and decide on an actual name for the system, which effected much more than just Alabama. (As an additional note, it now appears that the destruction of Dodson, Louisiana, was actually done by an EF1 tornado--has anyone else heard of a case of straightline winds being initially blamed for what turned out to be tornado damage, instead of the other way around?) rdfox 76 (talk) 13:16, 6 May 2009 (UTC)

"Washington, DC Derecho 2012"
Time to add a new entry! 2 people confirmed dead and 1.5M w/o power as of this morning's (Storm hit me in Fairfax, VA around 11:00PM June 29) Washington Post website. — Preceding unsigned comment added by Dag in va (talk • contribs) 11:16, 30 June 2012 (UTC)

7/24/12 event
The second one this summer? http://www.accuweather.com/en/weather-news/live-storms-with-fierce-winds-aim-for-chicago/68391 DBishop1984 17:58, 24 July 2012 (UTC)

Definition of Notability

 * What exactly would be defined as notable? I don't really understand what the criteria for notability is here. Winds? Impact? Someone please clarify. Dustin   talk  16:04, 9 December 2013 (UTC)


 * I found a derecho here: http://www.srh.noaa.gov/tsa/?n=weather-event_2013July23
 * Different approach to my question, though I was initially thinking in terms of a list of "biggest" or "most destructive" derechos. Right now it seems like an esoteric word that is being used for an unclear purpose. Is it possible that there is a trend of increasing numbers of derechos related to climate change? Or is this one of those prior conditions that is just acquiring a more precise label for reasons unknown? Shanen (talk) 20:04, 12 August 2020 (UTC)

June 22-23 2015 derecho?

 * I think that the derecho would be considered notable as it had over 600 reports of wind damage. Jdcomix   talk  19:48, 14 November 2015 (UTC)

May 14 and 15 Derechos
I think there should be an article comining both events as they were both significant and happened within 300 miles of each other. MegaEarthquake (talk) 05:56, 17 May 2018 (UTC) I'm gonna draft one up for the May 15th one, it's the first derecho to hit NYC in what, 12 years or so? Monstarules (talk) 16:14, 18 May 2018 (UTC)

NY and southern New England t-storm wind event on October 7, 2020
The thunderstorm wind event on October 7, 2020 across eastern New York and southern New England(mainly MA) has been classified as a serial derecho by the SPC. This had a 320 mile long damage swath and distributed widespread 75+ MPH wind gusts. I was hit by this just after 5 PM that evening. Lost power and didn't get it back until 6:42 the next morning. There were tons of trees down in my area. Anyways, here's a new entry. https://www.weather.gov/aly/High-End_Severe_Weather_Event_October_7_2020 https://www.spc.ncep.noaa.gov/climo/gm.php?rpt=201007_rpts Bostonfan2004 (talk) 12:21, 13 October 2020 (UTC)

Derecho Criteria
According to the NWS Storm Prediction Center, the following criteria is still valid: By definition, if the swath of wind damage extends for more than 250 miles (about 400 kilometers), includes wind gusts of at least 58 mph (93 km/h) along most of its length, and also includes several, well-separated 75 mph (121 km/h) or greater gusts, then the event may be classified as a derecho.

If an event doesn't meet this criteria, please don't add it. I've removed several events that just don't meet the criteria. "Derecho" is intended to mean the strongest and most robust of MCS events. Not every squall line is a derecho.

July 2021 Wisconsin event
I noticed a bit of an edit war has taken place concerning this one. The cited storm reports for that day do not support what's been written in the notes for either 90 mph wind gusts, or 37 tornadoes. There were 18 tornado reports in Wisconsin, including multiple for a single tornado. It doesn't seem to meet the derecho criteria for the time being. Blizk2 (talk) 16:38, 3 December 2021 (UTC)

Iowa Derecho 2020
Not sure why this is not on here as it is now the US most expensive thunderstorm. 770 square miles of Iowa devastated. Winds in our area alone were 120 mph and lasted 45 minutes 166.181.80.218 (talk) 18:24, 1 July 2022 (UTC)

Clarification
So there are two interesting events on this list where they are called derecho but don't meet the criteria:

May 25, 2000 North Carolina Derecho: the source that is sited mentions it being a derecho but looking at the source as well as SPC storm reports show that it traveled fewer than 100 miles

June 2008 Omaha derecho June 27, 2008: I found a case study on the event that referred to it as the Omaha derecho, but looking at storm reports and the case study the storm didn't travel very far and was defined as a gravity wave. The system itself would travel 400 miles but only produced damaging winds in Omaha and at the end of its life.

Also, another discrepancy

October 24, 2011 derecho: The event was similar to that of the October 2010 derecho and traveled 400 miles from Illinois to the Appalachians and brought damaging winds to the entirety of 4 states. However, skimming through the reports I found that only one sig wind report and no source I found called it a derecho.

What should be done on these? Jamisonsupame (talk) 02:41, 18 July 2022 (UTC)

June 18, 2023 southern plains derecho
The derecho formed in southwestern Kansas on the late afternoon hours of June 18, 2023 the storm continued to strengthen before hitting the Tulsa area with winds up to about 90-100 mph a 123 mph wind gust was reported in Tulsa, Oklahoma the storm also knocked out power to over 200000 Eli22512 (talk) 19:16, 21 June 2023 (UTC)


 * Yep. I was there. It was Wikipedia worthy if these others are. Jawz101 (talk) 02:14, 17 September 2023 (UTC)

May 4th and 5th 1989 Texas derecho
Don't forget to add this one. It traveled over 900 miles and Fort Worth experienced 100 mph winds. It's well documented on SPC/NOAA 96.40.41.231 (talk) 04:50, 25 May 2024 (UTC)


 * Forgot to add the year... 1989 96.40.41.231 (talk) 04:54, 25 May 2024 (UTC)

We’ve got another one!
Another Derecho likely ongoing. Has tracked over 600 miles from (at least) Paducah to near Washington DC and is still ongoing. 2601:5C5:4380:FD80:5D80:9ADE:8F4:56F2 (talk) 01:43, 27 May 2024 (UTC)
