Bheki draft

Question about reference

Hi:

Could someone give me a reference about the "official" start as end of the 2024–25 South-West Indian Ocean cyclone season. It is said in the text: 15 November 2024 to 30 April 2025, with the exception for Mauritius and the Seychelles, for which it will end on 15 May 2025. However, I could not find a weblink to corroborate that.

Pierre cb (talk) 04:34, 16 November 2024 (UTC)

https://en.wikipedia.org/wiki/Tropical_Low_01U_(2024); Is also TC 3S… could we include it?

1U, according to the JTWC, is actually 3S. Should this be mentioned in the article or not? 🍋 🍋(talk!) 17:00, 27 November 2024 (UTC)

If you mean the lead of the article, then no, because since the system has given the official TCWC BoM, we should refer to it. HurricaneEdgar 18:45, 27 November 2024 (UTC)

Cyclone Chido

This series of editions is wrong. Althought Meteo-France has upgraded Chido to tropical cyclone, the JTWC has only winds of 75 knots (https://wiki.chlod.net/jtwc/text/2024-12-11-0750-sh0425web.txt and https://www.metoc.navy.mil/jtwc/products/sh0425web.txt) which set the cyclone to an equivalent of category 1 in the Saffir-Simpson scale.

Pierre cb (talk) 15:07, 11 December 2024 (UTC)

RSMC La Reunion is the official naming and forecasting agency for tropical cyclones in the Southwest Indian Ocean. The Joint Typhoon Warning Center (JTWC) is a US military agency that also monitors tropical cyclones in this basin and other, but their naming and forecasting strength readings is not official my any means. WeatherFollower (talk) 21:50, 8 February 2025 (UTC)

Chido Wiki?

I think it's necessary seeing as its forecast to hit Mozambique with winds of 100kt Also as it made a category 4 on a island near Madagascar, and is brushing Madagascar as a category 3. 2601:846:580:32D0:1159:B4A2:80A6:280A (talk) 14:45, 13 December 2024 (UTC)

your lucky it got an article on wikipedia 173.47.225.28 (talk) 14:48, 14 December 2024 (UTC)

Category 2 equivalent for Dikeledi ???

Can somebody provide a reference for an intensity of category 2 equivalent of Dikeledi by the JTWC? As far as I can find in their archives (https://wiki.chlod.net/jtwc/text/) the cyclone never had more than 75 knots sustained winds which is category 1. This was introduced by an IP and I corrected. Pierre cb (talk) 15:01, 13 January 2025 (UTC)

This is presumably derived from the JTWC operational best track for the storm: https://www.ssd.noaa.gov/PS/TROP/DATA/ATCF/JTWC/bsh072025.dat. — Iunetalk 18:46, 13 January 2025 (UTC)

dikeledi article

The storm is somewhat significant with it making a Category 2 equivalent landfall in Mozambique, reaching a Cat 3 peak that far south, impacts in Madagascar.. I feel it deserves an article so can someone make it Airplaneboi77 (talk) 16:00, 16 January 2025 (UTC)

Agreed Dikeledi could use an article. Feel free to start a sandbox. ♫ Hurricanehink (talk) 18:59, 16 January 2025 (UTC)

I think I started an edit war

Is Vince Very Intense Tropical Cyclone or Intense Tropical Cyclone? 210.3.50.94 (talk) 02:10, 7 February 2025 (UTC)

According to RSMC La Réunion Vince was an Very Intense Tropical Cyclone. WeatherFollower (talk) 21:42, 8 February 2025 (UTC)

Mfr says it’s a Very Intense Tropical Cyclone I hate tropical cyclones (talk) 00:14, 10 February 2025 (UTC)

Do NOT use JTWC / Only use RSMC La Réunion (Met France) for cyclone information.

RSMC La Reunion is the official naming and forecasting agency for tropical cyclones in the Southwest Indian Ocean. The Joint Typhoon Warning Center (JTWC) is a US military agency that also monitors tropical cyclones in this basin and other basins, but their naming and forecasting strength readings are not official by any means. This is because the JTWC is not a member of the World Meteorological Organization (WMO), which is the international body that coordinates the naming and forecasting of tropical cyclones. As a result, the JTWC's naming and forecasting is not used by any country in the Southwest Indian Ocean, and should not be used in this article for defining when a system has changed strength or gained a name. WeatherFollower (talk) 21:53, 8 February 2025 (UTC)

JTWC uses sshws and 1 minute sustained winds

MFR uses the “ Southwest Indian Ocean Tropical Cyclone Intensity Scale”

With 10 minute sustained winds 210.3.50.94 (talk) 00:11, 10 February 2025 (UTC)

Should we create a separate article for Garance?

It’s threatening Reunion as the strongest storm to strike the nation. Corgimations (talk) 02:57, 27 February 2025 (UTC)

Sure, make it 210.3.50.94 (talk) 02:58, 27 February 2025 (UTC)

I agree. Ever since RSMC La Réunion upgraded Garance to an intense tropical cyclone, I knew La Réunion was really in danger. CasualCycloneTracker180897 (talk) 00:22, 28 February 2025 (UTC)

I see someone create a draft Draft:Cyclone Garance for Garance, feel free to work on it. --A1Cafel (talk) 13:27, 28 February 2025 (UTC)

Just submitted it Pillar8908 (talk) 15:11, 1 March 2025 (UTC)

Sorry, I revert it. The draft seems incomplete, at least the MH section requires improvement. --A1Cafel (talk) 13:32, 3 March 2025 (UTC)

How many left do this draft complete? MAS0802 13:47, 3 March 2025 (UTC)

Right now the Garance draft is a duplicate of the season article. It needs to be expanded with actual impacts and preparations. ♫ Hurricanehink (talk) 18:10, 3 March 2025 (UTC)

It looks like it just needs some more information added to it like the peak intensity and some other info but I think once everything is added in it could be published/submitted for review. I think the damage is $100-200 million? Laursparkly (talk) 07:09, 9 March 2025 (UTC)

The damage estimates are currently $170-200 million HurricanesAreInteresting (talk) 15:06, 10 March 2025 (UTC)

That is Euro (£), in currency of US Dollar ($), estimated 200-220 million. MAS0802 15:32, 10 March 2025 (UTC)

Do we need an article about Vince? A category 4/5 seems too important to not have an article

If bheki got an article, then Vince should too. Pillar8908 (talk) 15:18, 1 March 2025 (UTC)

Importance is more measured in how much impact a storm did to people. I would say the much higher priority is the article for Garance. ♫ Hurricanehink (talk) 17:32, 1 March 2025 (UTC)

Bheki never got an article 210.3.50.94 (talk) 06:03, 4 March 2025 (UTC)

Hurricane Kristy in the 2024 Pacific Hurricane Season doesn't have a page despite reaching category 5 strength. HurricanesAreInteresting (talk) 14:23, 5 March 2025 (UTC)

I remember someone start a draft for Bheki, but soon be declined because of inadequate information. I also doubt if Bheki caused enough damage that deserves an article or not. --A1Cafel (talk) 06:02, 6 March 2025 (UTC)

Honde needs an article

It has caused 3 deaths and heavy rain on Mozambique and Madagascar

It’s large size also caused a big storm surge 210.3.50.94 (talk) 00:01, 6 March 2025 (UTC)

If you have adequate information that you think the season section cannot cover, feel free to start a draft (Personally I think Honde deserves an article, but I don't have much information right now). --A1Cafel (talk) 06:00, 6 March 2025 (UTC)

Garance also deserves an article, but it is being drafted currently. HurricanesAreInteresting (talk) 14:12, 6 March 2025 (UTC)

I create Draft:Cyclone Honde, hope someone help to finish them. MAS0802 13:41, 10 March 2025 (UTC)

Jude needs an article too

Cyclone Jude made landfall and should have an article. HurricanesAreInteresting (talk) 15:05, 13 March 2025 (UTC)

Sure. Here it is Draft:Cyclone Jude, someone created it before. MAS0802 11:32, 14 March 2025 (UTC)

I think Jude deserves an article 203.218.159.12 (talk) 07:44, 16 March 2025 (UTC)

Definitely, makes me think of Dikeledi 210.3.50.94 (talk) 23:47, 16 March 2025 (UTC)

Courtney not a SWIO VITC

If you look, it was at 90.2, which is outside the basin, so Courtney isnt a VITC for this season despite the MFR having warned on it. Noah, BSBA^Talk 14:10, 29 March 2025 (UTC)

@Accordthemusician, HurricanesAreInteresting, and Hurricane Noah: I feel like we need to discuss Courtney's peak intensity for the record. Within their first advisory at 12z, RSMC La Reunion called it a VITC with 10-minute sustained winds of 120kts and analyzed it at 90.2E, which would make it a Category 5 Severe Tropical Cyclone on the Australian tropical cyclone intensity scale. They have since revised their 12z estimate to 90.1E and 110kts, which still makes it a Cat 5 STC in the Aus Region but downgrades it to an intense tropical cyclone in the SWIO.Jason Rees (talk) 21:53, 29 March 2025 (UTC)

@Jason Rees I see where you're coming from Accordthemusician (talk) 22:37, 29 March 2025 (UTC)

@Accordthemusician, HurricanesAreInteresting, Hurricane Noah, MAS0802, Owen is the best GG, and Huuphuc310261: I am going to put an end to the edit war that is currently going on and state that Courtney was a Category 5 severe tropical cyclone in the Australian region per the BoM. For the time being, until the BoM updates their database later in the week, I have just taken the 110 kts/940 hPa that Reunion gives in its running best track for Courtney in the Aus Region for its peak intensity.Jason Rees (talk) 17:50, 1 April 2025 (UTC)

Stop Making Edit War

Stop making edit war for dissipated date about cyclone.

Post-tropical cyclone/Extratropical cyclone means it will not longer active by far. @Cooperbutchjuly @Christopher395 MAS0802 15:41, 2 April 2025 (UTC)

Tempête subtropicale

is there a storm category color for this stage if system number 15 become the first "subtropical storm". ~

Not yet I don't think, I just checked — since I can't edit it myself (template editor is required?), we'd need to wait until somebody with those permissions can do so. Cherkasy0 (talk) 11:37, 20 April 2025 (UTC)

In other wiki articles for hurricane/typhoon/cyclone seasons, the colour for subtropical is typically the same colour as the tropical storm stage. WeatherFollower (talk) 14:02, 23 April 2025 (UTC)

New "Subtropical Storm" category discussion

It appears MFR has added new "Subtropical Storm" category for subtropical systems starting with 35kt Source: ZCITA_202504201034.pdf

You are agree to change category for 35kt+ subtropical systems SD to SS? ElenaCyclone (talk) 11:36, 20 April 2025 (UTC)

I think we could use the global category for now (ss/subtropical) and then change it later once somebody gets around to making a new one? Same goes as per what I said in the discussion above. Cherkasy0 (talk) 11:42, 20 April 2025 (UTC)

Main problem is that previous 35kt subtropical systems from previous seasons like Issa from 2022 and Bransby from 2016 are still called subtropical depressions instead of subtropical storms so we don't know if it's new category introduction or accidentally put "Storm" instead of "Depression" ElenaCyclone (talk) 11:49, 20 April 2025 (UTC)

It is a new category — more information can be found in the WMO's operational plan for 2023 (https://wmoomm.sharepoint.com/:b:/s/wmocpdb/EYlTpV0sKLFAjl1s8ktbVBgBLNG3v60mFBTQ9TXnOcZZUw?e=GfpWcm, page 8) Cherkasy0 (talk) 12:28, 20 April 2025 (UTC)

Ah i see it's officially now SS category for SWIO according to both MFR and WMO ElenaCyclone (talk) 13:02, 20 April 2025 (UTC)

Making a page for Subtropical Storm Kanto...

As Kanto is the first system in the basin to be named as a subtropical storm (a new category for the basin starting this season), should the storm have it's own wikipedia article so signify this landmark? WeatherFollower (talk) 14:05, 23 April 2025 (UTC)

Nah the storm didn’t affect anyone. Hurricanehink mobile (talk) 15:07, 23 April 2025 (UTC)

Defintley not as the category will be retrospectively applied, just like all of the other categories used for TC/STC tracking.Jason Rees (talk) 00:08, 24 April 2025 (UTC)

not notable enough 203.218.159.12 (talk) 10:13, 28 April 2025 (UTC)

Cyclone Garance

I have looked to the references and I cannot find any mention of Cyclone Garance having costed $940 millions in damages. Could someone provide a credible reference for that???
