Tropical storm Akará deserves an article

Do you think it's a good idea to Akara your own article?

Splitting off List of South Atlantic tropical and subtropical cyclones?

This article isn't especially long, but the South Atlantic is in the process of becoming an actual basin. This is evidenced by the naming list, the regular advisories, and this document I came across today - [2][3] - the Integrated Center for Aeronautical Meteorology is set to become a Tropical Cyclone Advisory Centre in December 2026, so I could see the weather agency getting an article too. Either way, the South Atlantic is about to become a lot more formal of a weather basin, and having a separate list could be useful. I would keep the naming list on here, which would link to each named storm, while keeping Catarina and any other significant storms in the main article (perhaps as a part of climatology/impacts). ♫ Hurricanehink (talk) 20:12, 1 March 2026 (UTC)

Before I publish, does anyone have any feedback about how the list should be formatted? For example, should every storm get a bullet point, or an infobox? What should the intro be? ♫ Hurricanehink (talk) 23:08, 4 March 2026 (UTC)

I agree that including an infobox for every storm is beneficial; however, I’m unsure how the introduction should be. 🌀Hurricane Jacob (talk) 01:37, 5 March 2026 (UTC)

I think that the way the current article is formatted is the best way, i.e. having infoboxes only for the notable systems. I think that we'll have a hard time finding info on older ones, which are on the "Other systems" section, to justify infoboxes for them too. ABC paulista (talk) 02:25, 5 March 2026 (UTC)

True. 🌀Hurricane Jacob (talk) 02:28, 5 March 2026 (UTC)

As for the lead, maybe we should adopt a similar wording as used in the List of Pacific typhoons before 1850, for example. ABC paulista (talk) 02:33, 5 March 2026 (UTC)

I agree with this, however I am still opposed to Catarina not having an Infobox. I dont see a reason to not give it one, even if it is mentioned in the start of the article. Sria-72 (talk) 03:18, 5 March 2026 (UTC)

And also the 1991 storm should have an infobox. Sria-72 (talk) 03:19, 5 March 2026 (UTC)

By including the 1991 storm, you’re including non-notable cyclones. So infoboxes for everything then? Hurricanehink mobile (talk) 03:48, 5 March 2026 (UTC)

I think the 1991 storm doesn't need an infobox.🌀Hurricane Jacob (talk) 03:55, 5 March 2026 (UTC)

I think that the 1991 storm is pretty notable, for being the first one to be actively monitored by an agency and still being the only recorded on the eastern part of the basin. ABC paulista (talk) 20:53, 5 March 2026 (UTC)

The source for the track map looks questionable. I didn’t think there was any official best track for the storm. Hurricanehink mobile (talk) 21:03, 5 March 2026 (UTC)

I mean regardless of that, I think that the 1991 storm is notable enough because of its formation area to be listed with an infobox. Sria-72 (talk) 21:12, 5 March 2026 (UTC)

Now I think the 1991 storm deserves an infobox. 🌀Hurricane Jacob (talk) 21:46, 5 March 2026 (UTC)

There isn't a official best track because no agency monitor the basin until 2011, but the NHC did report it back then. The "best track" seems to have been independently analyzed by a chilean meteorogist named Luís Muñoz, and some other tracks presented here also seem to have been done using his data. It seems to be a similar situation to Gary Padgett's, which also has some of his data used to generate some of the tracks used here. ABC paulista (talk) 21:28, 5 March 2026 (UTC)

Update - Draft:List of South Atlantic tropical and subtropical cyclones - here is a draft I made, copying all of the storms from the main article. Since there's pretty obvious support for such a split, one of the big questions is whether every system should get an infobox or not. ♫ Hurricanehink (talk) 17:26, 2 March 2026 (UTC)

Support - This seems like a sensible change, as it keeps the South Atlantic consistent with other tropical cyclone basins. 🌀Hurricane Jacob (talk) 21:05, 1 March 2026 (UTC)

Support - But I'd move the whole of the sections 3 and 4. I feel it'd be weird, and somewhat arbitrary, to move some systems while keeping others here.— Preceding unsigned comment added by ABC paulista (talk • contribs)

Yes, absolutely. ♫ Hurricanehink (talk) 22:15, 1 March 2026 (UTC)

Support - Would you mind specifying what you mean by a “separate list”? Im for this, given that section 3 and 4 need some reworking and the aforementioned formality that the article should begin to have now with this likely becoming an official RSMC basin this December.

ViridLeWiki (talk) 22:32, 1 March 2026 (UTC)

@ViridLeWiki: - we probably need to take sections 3 and 4 and make a new list, better reworked and properly formatted. ♫ Hurricanehink (talk) 06:52, 2 March 2026 (UTC)

Support Why is catarina missing from the draft? Sria-72 (talk) 21:34, 2 March 2026 (UTC)

It’s the opening image, and it’s listed under 2000. Hurricanehink mobile (talk) 21:56, 2 March 2026 (UTC)

Why doesn't it have an infobox? Sria-72 (talk) 22:04, 2 March 2026 (UTC)

@Sria-72: as I said before, one of the big questions is whether every system should get an infobox or not. I already made Catarina the main image for the draft, and it has its own article, so an infobox is just going to add space. ♫ Hurricanehink (talk) 04:22, 3 March 2026 (UTC)

Timeline of south Atlantic cyclones

I made a timeline of storms similar to a tropical cyclone season, but I did it a bit differently. Instead of putting the storms in time order (eg. Andrea to Melissa) I put them in order of time of year and listed what year they occured. For example, Hurricane Catarina is placed near March and has the label "Catarina (2004)". Because south atlantic cyclones are unusual, I was unsure if it belongs on this article, but I won't add it until many people accept it. If it needs modifications, feel free to change it as necessary. Below, you can see my concept for this timeline:

CycloneTheta (talk) 07:38, 2 March 2026 (UTC)

Looks great! 🌀Hurricane Jacob (talk) 07:41, 2 March 2026 (UTC)

Support - This would be a great addition, but what happens eventually when enough systems form and it clutters the whole timeline? ViridLeWiki (talk) 12:32, 2 March 2026 (UTC)

These timelines I made do prevent clutter, but it’s hard to see the storm thingies…

by the way, the link’s here if you want to look at the timelines. 🍋 🍋(talk!) 13:33, 2 March 2026 (UTC)

@LemonJuiceIsSour I just thought it would be an interesting thing to make, and I thought it might fit here. I didn't add it as I wasn't sure if it belonged here. CycloneTheta (talk) 22:45, 2 March 2026 (UTC)

Oppose - It's not a proper timeline, but rather a sort of "dateline", which I feel it could become cluttered really fast. Also, the way data is organized seems too similar to the Climatological statistics section, it feels redundant. Also not a fan of how it includes only the systems cited as "notable", while ignoring the other ones. ABC paulista (talk) 16:26, 2 March 2026 (UTC)

• I could only see this working as part of a climatology section in a new (proposed) List of South Atlantic tropical and subtropical cyclones. But even then, as ABC noted, I think it would be more useful to have a chart of every single storm, sortable by date, by year, by name (if applicable), by death, by damage. ♫ Hurricanehink (talk) 17:08, 2 March 2026 (UTC)

Caiobá track map needed

Does anyone know where to access MARINHA's ATCF data? I would like to create a track map for Caiobá and to include it in the 2026 worldwide TC map. Same goes for the subtropical depression that co-existed with it OreoStar-fait (talk) 04:19, 22 March 2026 (UTC)

I don't think that they generate this kind of data, and even if they did so it wouldn't be useful for us, since their best track data work in 12-hour intervals, whereas the WMO standard is 6-hour intervals, and our project follows the latter. ABC paulista (talk) 04:50, 22 March 2026 (UTC)

Oh I see. I saw in Akara's track image, some source code was laid out albeit I am not sure where it was derived from. Perhaps was it from WMO? OreoStar-fait (talk) 05:33, 22 March 2026 (UTC)

According to the image file, the data comes from this page. Actually, most of data used to generate the tracks for South Atlantic cyclones comes from these independent analysis from meteorologists. ABC paulista (talk) 14:06, 22 March 2026 (UTC)

Oh interesting. Strangely nothing on Caiobá or 01-2026 seems present tho OreoStar-fait (talk) 16:37, 22 March 2026 (UTC)

These kind of work take some time to be done, wait some months and either Luiz Muñoz or Gary Padgett/Steve Young will have something on it. ABC paulista (talk) 17:01, 22 March 2026 (UTC)

I would rather not have track maps from a blog, so should we remove the unofficial track maps? Hurricanehink mobile (talk) 16:57, 22 March 2026 (UTC)

By this logic, all track maps would be removed since pretty much all of them use data from blogs or similar alternative sourcing. ABC paulista (talk) 17:17, 22 March 2026 (UTC)

Not if the track maps use data from the Brazilian Navy. My issue is more the sourcing. Australiasevereweather cites using the "DIRECTORATE OF HYDROGRAPHY AND NAVIGATION" (which is the Brazilian Navy). ♫ Hurricanehink (talk) 22:15, 22 March 2026 (UTC)

The blog also cite using the TEMPESTADE TROPICAL AKARÁ: RELATÓRIO PÓS-EVENTO. (s. f.). En Marinha Do Brasil. Recuperado 12 de septiembre de 2025, de https://www.marinha.mil.br/chm/sites/www.marinha.mil.br.chm/files/u1894/relatorio_pos_evento_akara.pdf as a source, alongside other databases, including the Australia Severe Weather's one. ABC paulista (talk) 22:59, 22 March 2026 (UTC)

In that case, the blogs are probably fine, if they're not the ones who are making up the information, but rather reporting what the warning center said. In the above case and others, ideally we would cite the Brazilian Navy directly, to reduce concerns of original research. These are the annoying downsides of dealing with a quasi-basin without great recordkeeping! ♫ Hurricanehink (talk) 17:43, 23 March 2026 (UTC)

I wonder if there's some kind of archive that has the fixes the Brazilian Navy put out for cyclones. That would be helpful OreoStar-fait (talk) 17:55, 23 March 2026 (UTC)

The brazilian navy doesn't archive their advisories, only their synoptic charts, but we do our own archiving for the fixes. The links are on the upper side of this talk page, on the "Specialized archives" section, divided by years. ABC paulista (talk) 21:02, 23 March 2026 (UTC)

Actually, they both seem to do their own reanalysis of the data that the navy and other provide. Meteorologia Extrema Chile even provides an image comparing the different tracks for Akará, composed of different datasets which also include Australia Severe Weather. ABC paulista (talk) 21:07, 23 March 2026 (UTC)

In that case, I contacted the Brazilian Navy department directly. I wrote this (and translated into Portuguese):

Good afternoon. I am a Wikipedia editor, and I am seeking information on tropical cyclones in the South Atlantic Ocean. 
Do you have an archive of storms in the basin that show the position and intensity? Our goal is to make a map based on official data.
