Other Basin Talkpages (2020): Atlantic - W. Pacific - E. Pacific - S. Hemisphere - N. Indian

New for 2020: A forum page to discuss tropical cyclones that form outside of the usual regions. This includes formations in the South Atlantic, Mediterranean, or elsewhere unusual. Any storm that forms outside of normal basins will be discussed here. ~ Steve 🎉 Happy2020!🎆 05:22, January 2, 2020 (UTC)

Hmm, is this page really needed? We usually add South Atlantic and Mediterranean storms to the Atlantic if they form, I don't think we need a separate page just for them or southeast Pacific storms. Ryan1000 14:57, January 2, 2020 (UTC)
I would argue in favor of this page. When going to the Atlantic forum, I usually am not thinking of the Mediterranean or South Atlantic. Moreover, a reader could mistake a storm in those basins for a North Atlantic tropical cyclone. That being said, I do not think it is logical to archive this page every year given the rarity of these systems (e.g. Katie and Lexi have been the only two cyclones recorded in the Southeast Pacific). AndrewTalk To MeContribsMail Me 18:31, January 2, 2020 (UTC)
Andy makes some good points. The South Atlantic and Mediterranean are completely separate from the usual North Atlantic season. We should probably archive this forum by decade (e.g. 2020-29, 2030-39, etc.) considering the rarity of formations here. I also prefer the "Southeast Pacific" header to instead be "Elsewhere", because that's perhaps the rarest area for storms to form (much rarer than even the South Atlantic and Mediterranean) along with the Black Sea, Great Lakes (like the famous 1996 Huron cyclone), and any other strange regions. Any storm that forms in the southeast Pacific, Black Sea, Great Lakes, etc. will go under "Elsewhere". ~ Steve 🎉 Happy2020!🎆 01:26, January 3, 2020 (UTC)

I supose that makes sense, we'll add these storms under this separate forum, but in that case, I concur with Steve; since storm formation is rare in the other areas, the archives below the main header will be done by decade, but no individual archives unless the individual storm is notable, like Catarina was.

South Atlantic

Subtropical Storm Kurumí

AOI:South of Brasil

Interesting things going on in the SAtl right now. This storm was being predicted by multiple models for several days, and the Brasilian Met office has said that they could issue advisories if tropical transition occurs. It is all over the Brasilian news right now. We could be seeing our latest STC or even TC, and GFS forecasts rapid to explosive intensification. While the GFS forecast seems unlikely, given how bad GFS has been of late, this could still be very very interesting. Models take this system to at least 50-55 kt. Unfortunate no one noticed this until now. -- JavaHurricane 15:37, January 22, 2020 (UTC)

Interesting, this could become Kurumí if it forms. The Brazil meteorological center has now issued a "special warning" for possible subtropical cyclogenesis. It will be fascinating to see how this all plays out in the next few days. ~ ☃ Steve ❄ Message MeMy Edits📧 22:41, January 22, 2020 (UTC)

Subtropical Depression One

Special warnings have been issued by Marinha Brazil for a subtropical depression, but ASCAT indicates that this is a singular system with the characteristics of extratropical, subtropical and tropical cyclones all mixed up. -- JavaHurricane 17:23, January 23, 2020 (UTC)

Currently 1007 mbar according to Marinha Brazil. I can't wait to see the future evolution of this system. ~ ☃ Steve ❄ Message MeMy Edits📧 18:55, January 23, 2020 (UTC)

Subtropical Storm Kurumí

Brazilian Navy has upgraded this to a subtropical storm and named it Kurumi. ~ KN2731 {talk} 04:37, January 24, 2020 (UTC)

Subtropical Depression Kurumí

Seems to be down to a depression according to Brazilian Navy, 1000 mbar with Force 7 wind, which is around 35 mph. ~ ☃ Steve ❄ Message MeMy Edits📧 04:12, January 25, 2020 (UTC)

Remnants of Kurumí

Now no where to be found on the Brazilian Navy site, which means it's dead. ~ ☃ Steve ❄ Message MeMy Edits📧 18:55, January 26, 2020 (UTC)

Subtropical Depression Five

Subtropical Depression Five

Yep. A depression is currently active and weakening over the SATL. -- JavaHurricane 16:48, April 16, 2020 (UTC)

Remnants of Five

Appears to be dead, as I don't see it on the Brazilian Navy site. This was so short-lived and insignificant that I completely missed it lol. ~ Steve 🙏🏻 Praying for the worldto recover from coronavirus.📧 17:05, April 18, 2020 (UTC)

Subtropical Storm Mani

Subtropical Storm Mani

New SATL system according to the Brazilian Navy. 40/1006. Now named, although this was a SD earlier. Nutfield001 (talk) 04:28, October 26, 2020 (UTC)

Wow. 2 systems in a year. This is rare.ʙɪʟʟ2903 (talk) 09:31, October 26, 2020 (UTC)

I wouldn't say it's entirely rare Bill, since 2011, 2016 and 2019 all had two systems form within their respective years. Anyway Mani's pressure is down to 1004 mb. Nutfield001 (talk) 03:35, October 27, 2020 (UTC)

Remnants of Mani

Brazilian Navy's weather chart states Mani has weakened back to a low. Nutfield001 (talk) 18:22, October 28, 2020 (UTC)

Subtropical Storm Oquira

Subtropical Storm Oquira

Now at 40mph/1002mBar, Oquira is the 3rd system this year. The most active South Atlantic hurricane season is 2020 (2020 nature still amazed us during its last days.ʙɪʟʟ2903 (talk) 12:00, 30 December 2020 (UTC)

Post-Tropical Cyclone Oquira

February 2021 storms off Brazil

These systems went unnoticed here while they were active but I'll just put them anyway. Both of them formed off the coast of the Rio Grande do Sul state. Jas (Anonymous 2.0) (talk) 21:31, 17 February 2021 (UTC)

Tropical Storm 01Q

The first one was 01Q, a tropical storm that only recognized by NOAA. It was never monitored by the Brazilian Navy, at least operationally. It was an extratropical system initially, until it transformed to a bomb cyclone on February 4. By February 5-6 it transitioned to a subtropical cyclone before becoming an actual tropical system. Lowest pressure was at 990 mb, while its maximum sustained winds were at 65 kph (40 mph; 1-min). Jas (Anonymous 2.0) (talk) 21:31, 17 February 2021 (UTC)

Subtropical Depression 02Q

The second one was designated as 02Q, a subtropical depression that was recognized by existed from Valentine's Day until today. Lowest pressure was estimated at 1002 mb; highest 1-min sustained winds at 55 kph (35 mph). Jas (Anonymous 2.0) (talk) 21:30, 17 February 2021 (UTC)

Subtropical Storm Potira

April 2021 Subtropical Depression

The Brazilian navy has designated this system off the coast of southeast Brazil as a subtropical depression. Doesn't have a numerical designation as far as I'm aware yet.  ~ Roy25   Talk | Contributions   02:43, April 20, 2021 (UTC) 

Subtropical Storm Potira

Upgraded to a subtropical storm and named Potira by Marinha.  ~ Roy25   Talk | Contributions   14:08, April 20, 2021 (UTC) 

Post-Tropical Cyclone Potira

Downgraded to a remnant low earlier today.  ~ Roy25   Talk | Contributions   04:33, April 26, 2021 (UTC) 

Subtropical Storm Raoni

Subtropical Storm Raoni

We got this thing off the coast of Uruguay/Brazil.  ~ Roy25   Talk | Contributions   22:25, June 29, 2021 (UTC) 

I think Mother Nature forgot to check the calendar. What the heck is this thing spinning about in the South Atlantic in the middle of their winter? In fact, it's already pretty strong... at least 60 mph. TC formation here is quite unusual in the first place, but in the middle of winter? Mother Nature has truly been playing jokes on us lately, from this storm, to North Atlantic MDR activity that is more typical of peak season, to the Northwest U.S. heat wave causing temps to reach the 110s in more coastal cities such as Portland... ~ Steve (Message Me) (My Edits) (📧) 03:40, 30 June 2021 (UTC)
Amazingly, Raoni is still active as of this writing. Hopefully it has not caused any major damage in Uruguay and Brazil. Jas (Anonymous 2.0) (talk) 10:24, 1 July 2021 (UTC)

Remnants of Raoni

And according to the Brazilian Navy, Raoni is out. Jas (Anonymous 2.0) (talk) 12:38, 2 July 2021 (UTC)

Mediterranean

Medicane Ianos

Looks to be a potential Medicane forming in the Ionian Sea to the south of Italy, forecast to head for Greece. The appearance right now is pretty reminiscent of many of the sheared tropical storms in the Atlantic this season! --Patteroast (talk) 11:55, September 16, 2020 (UTC)

What is interesting is that the Mediterranean is so hot (28-30 C sst).ʙɪʟʟ2903 (talk) 12:16, September 16, 2020 (UTC)

It is officially a medicane now, but I can't find any intensity numbers on it, other than 40 mph a couple of days ago. Tacoman7 (talk) 05:36, September 17, 2020 (UTC)

Winds up to 60 mph, expected to get near or obtain hurricane strength. Tacoman7 (talk) 20:02, September 17, 2020 (UTC)
Historical event already made when Alpha and Ianos both landfall at Europe on the same day: September 18th.ʙɪʟʟ2903 (talk) 04:05, September 19, 2020 (UTC)

Medicane Nearchus/Cyclone Apollo

Oh, there was a Medicane during the All Saints'/Halloween holiday, and it only dissipated earlier today. It was named Apollo by Italy, and Nearchus by Greece. Peaked at 65 mph/100 kph, and left at least 5 fatalities and 2 missing during its relatively long life. Damage totals at 180 million Euros ($210.23M).
