== Map of Alma ==
I have taken some liberties with your image of Alma. I found that the image was 1,124,365 bytes (24 bits/16 million colors). I did a little work and found that by converting the image to 8 bits (256 colors) (non-interlaced & optimized palette) (.png) the image reduced down to 91,902. However, converting to .jpg (24 bits) and with a compression of 43% the image yieled a size of 27,195 bytes with no distortion.

*Summary:
*Original file: 1,124,365 bytes (.png)
*Experimental .png : 91,902 bytes
*New file: 27,195 bytes

An administrator told me that they were not concerned with file sizes. I believe Wikipedia could, in the future, be bogged down in large files.

I will give you full credit on the updated image page.

:Actually, since all revisions of an image are stored on the server, we now have a 91 KB file ''and'' a 1 MB file as well. [[User:Titoxd|Tito]][[Wikipedia:Esperanza|<span style="color:#008000;">xd</span>]]<sup>([[User talk:Titoxd|?!?]])</sup> 19:18, 4 July 2006 (UTC)

:While standard PNG files are quite inefficient, converting to paletted PNG or to compressed JPEG format is lossy and DOES have distortion (however small).  If size is a concern it would be better to change the track generator program to put new images into the desired format rather than convert all old ones.  Note that the amount of old track images is huge (see the commons) and converting any reasonable number of them by hand would be a daunting and error-prone task. — [[User:Jdorje|jdorje]] <small>([[User_talk:jdorje|talk]])</small> 03:49, 27 August 2007 (UTC)

== Direction of tracks ==

In looking at some of the tracks, I came to think that it might be beneficial to have some indication where the storm formed and where it died. For some storms, it's hard to tell what direction the storm took along the indicated path.  <small>—The preceding [[Wikipedia:Signatures|unsigned]] comment was added by [[Special:Contributions/{{{IP|{{{User|65.220.47.130}}}}}}|{{{IP|{{{User|65.220.47.130}}}}}}]] ([[User talk:{{{IP|{{{User|65.220.47.130}}}}}}|talk]]) {{{Time|18:10, August 23, 2007 (UTC)}}}</small><!-- Template:UnsignedIP --> <!--Autosigned by SineBot-->

:Yes it would.  How would you go about indicating this?  It's rather tricky since data points may be arbitrarily close or far apart, and because the track needs to look reasonably good at a thumbnail size as well. — [[User:Jdorje|jdorje]] <small>([[User_talk:jdorje|talk]])</small> 03:50, 27 August 2007 (UTC)

== Squares and Triangles ==

What do the squares and triangles represent in the storm path maps? [[User:MikeM2010|MikeM2010]] ([[User talk:MikeM2010|talk]]) 06:33, 27 July 2008 (UTC)
: Triangles represent generally tropical disturbances, post-tropical cyclones, extratropical cyclones or other types of low. Squares generally represent subtropical storms. -[[User:Ramisses|Ramisses]] ([[User talk:Ramisses|talk]]) 15:51, 27 July 2008 (UTC)

== Cumulative track maps ==

It would be very helpful if we had separate data files for cumulative track maps that need to be regularly updated (such as those in [[List of retired Atlantic hurricane names]] and [[List of retired Pacific hurricane names]]). Since I have those two files, I posted them at [[Wikipedia:WikiProject Tropical cyclones/Tracks/Retired Atlantic]] and [[Wikipedia:WikiProject Tropical cyclones/Tracks/Retired Pacific]].

==Projection==
The orthographic map you're using is a little skewed so the latitudes and longitudes aren't quite 1:1.  Do you use a transformation matrix to compensate?  <span style="font-size: smaller;" class="autosigned">—Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[Special:Contributions/67.86.161.80|67.86.161.80]] ([[User talk:67.86.161.80|talk]]) 20:27, 9 September 2010 (UTC)</span><!-- Template:UnsignedIP --> <!--Autosigned by SineBot-->
: We are using a [[equirectangular projection]], and we're not applying any corrections to it, as most of the distortion is in high latitudes where tropical cyclones usually don't exist. While I don't think anyone would be opposed to switching projections, we'd have to figure out which projection to use (a pretty complex problem by itself), and someone would need to take the lead on applying the transformation to the image matrix.

== Ease of use ==
Hi. I was looking into how the current storm tracks were generated, and ended up here. To be honest, I don't find this method easy at all. For an average editor with moderate web skills (like me), the downloading/launching procedure is somewhat in alien language. ;) I agree that something is better than nothing, but I just want to know, how possible is it to compile the current software into something like an .exe file, so that it may be simply downloaded (in the usual fashion) and installed like any other software, and used by any other editors?

== Color coding on track maps confusing ==

Aren't the colors used to differentiate a Tropical storm from a Tropical depression confusingly similar? When looking at many of these track maps I find it difficult to see T-storm <-> T-depression transitions due to their color code being so similar. If possible I would suggest looking into adjusting the colours used for these two classes in order to more clearly differentiate them. Thanks for reading!

== Track map generator now handles HURDAT2 ==

Hi all,

Starting from r192, the track map generator can now parse best-track files in the HURDAT2 format. In order to do that, you would invoke the track map generator something like this:
<syntaxhighlight lang="bash">
./track --year 2004 --name ivan --format hurdat2 --input ../data/hurdat2/natlantic.hurdat2.txt
</syntaxhighlight>

The main changes are:
# Add <code>--format hurdat2</code> to tell the program to use the new HURDAT2 parser (this parser will become the default in the future eventually, but for now, the program still defaults to HURDAT1).
# Add <code>--input ../data/hurdat2/natlantic.hurdat2.txt</code> to tell the program where the HURDAT2 best track file is located. This file should be included with the source code files when you download the new versions of the generator.

Also, I added some more logic for the automagic filling of <nowiki>{{WPTC track map}}</nowiki>; it will now recognize the correct hurricane season article and pre-fill the template with that info.

== Category Five dots are black ==

I've recently switched from using Ubuntu to Cygwin (64-bit) to create the tracks and for the most part it ran smoothly.

== [[Wikipedia:Manual of Style/Accessibility#Color]] compliance ==

Per the MoS - "Ensure that color is not the only method used to convey important information".  These tracks as being currently generated fail this standard.  For a color-blind or similarly impaired user, the intensity information could be hard to interpret. I have suggestions for long-term improvements:
# Use different symbols for each storm intensity. I suggest a triangle for depressions (△), square for storms (⬜), and circled-numbers for the SSHWS category levels (① ② ③ ④ ⑤). You can tint these using the same MOS-compliant color scheme proposed for use on the rest of the project. 
# Include a key to these symbols on the side or across the bottom of each track image. Include the storm intensity terms, and  preferably with the wind speed ranges, so that the information is easy to reference.
# When generating the tracks, zoom in as close to each track as you can, while still being able to give geographic context.
I don't see any need to worry about those images already generated, this is a long-term beneficial improvement. -- [[User:Netoholic|Netoholic]] [[User talk:Netoholic|@]]  03:23, 2 August 2014 (UTC)

::: {{ping|Netoholic}} I disagree with the notion that the tropical cyclone track maps require keys and the inclusion of additional symbols, and that this suggestion is not a feasible solution. With the current status of the tracks, there are already additional symbols for when cyclones were remnant lows, extratropical cyclones, and subtropical cyclones. Adding even more small shapes for even more classifications will make maps littered with multiple symbols measuring mere pixels across, and this will be utterly confusing on season and climatological maps where there there are usually hundreds if not thousands of individual data points of very high density. Adding small text to the categories of the Saffir-Simpson scale will furthermore exacerbate this issue as storms often trace over their former paths, covering up previous plots. One example of such an image is [[:File:Global tropical cyclone tracks-edit2.jpg]], where the high density of tracks and plots indicates that the implementation of this on a large scale is unfeasible, and that having such files as exceptions to the suggestion would undermine consistency maintained across hundreds of files.<br /><br />Furthermore, yes, [[WP:COLOR]] does indeed say that "Ensure that color is not the only method used to convey important information," and [[WP:Manual of Style/Accessibility#Images|the Accessibility guideline on images]] says that "Where possible, any charts or diagrams should have a text equivalent, or should be well-described so that users who are unable to see the image can gain some understanding of the concept." We already have an alternative to colors in the maps—it's the storm articles themselves, especially their meteorological histories which describe in detail the track and intensity of such tropical cyclones.

:::: Frankly, this is nonsense. For high-density maps like you mentioned, you can't even see the individual dots unless you expand the map to its highest size, and at that size, replacing unlabeled dots of color with symbols is entirely possible.  It wouldn't change the look of the map at all at a thumbnail size. I said right above you, [[WP:COLOR]] is '''not'' about "users who are unable to see", it is about helping those that cannot see ''well''. You have no idea what is feasible until you actually try.

: Putting on my maintainer hat, suggestions #1 and #2 will not be implemented. 
:* Enough reasons have been written here by others why #1 is a bad idea, but in particular legibility concerns are important, and we already use symbol shapes to indicate the meteorological status (i.e. tropical/subtropical/extratropical) of the storm. 
:* Suggestion #2 introduces internationalization issues, since the English Wikipedia is not the only project that uses these images, and having to upload separate maps for each project that uses our maps is not a productive use of anyone's time. Furthermore, introducing written text to the maps raises the possibility that we would be unable to release the maps to the public domain (one of the explicit goals of this project) due to [[Intellectual property protection of typefaces|issues with copyright protection]]. 
:* Suggestion #3 is useful, but we again run into the font copyright issue of #2. 
: As an aside, I will mention that the [[WP:ACCESS]] issues you bring up can be '''easily solved in prose''', which is something we have to do anyways (see [[Wikipedia:Manual of Style/Accessibility#Images]], in particular point #3), so these concerns are all very overblown.

::*To answer [[User:Titoxd|Titoxd]]'s claim #1 that this change would have "legibility concerns", I've put together a mockup of the method I suggested. You can see that at a thumbnail level, the difference is almost imperceptible, but when expanded, the accessible version becomes useful to those that have color vision impairments. I'll concede his point #2 about the on-image key/legend being a language problem, but providing distinguishing characteristics (other than color) to conform to [[WP:COLOR]] is entirely possible. Each project can then create a key/legend that is tailored to them. His claim about this "easily solved in prose" is referring to accessibility guidelines ''for the blind''.  My change request here is in accord with [[WP:COLOR]] which is about helping those people that have color vision impairments. Those people do not use browsing tools for the blind, they pretty much use standard browsers with their UIs configured for high-contrast modes.  It is those people that deserve to be accommodated by using better indicators on these track maps.   His comments about font copyright concerns is a complete non-starter. We aren't publishing an ''entire'' font here, we're using a few characters which we could even design ourselves if you ''really'' feel that such a thing would otherwise prevent public domain release. -- [[User:Netoholic|Netoholic]] [[User talk:Netoholic|@]]  05:14, 5 August 2014 (UTC)
:::* Actually, the addition of the "1" makes the Cat 1, Cat 2 and Cat 3 colors perceptively darker in my screen, which modifies the hue and reduces the contrast with the adjacent dark [[Blue Marble]] background, so the suggestion makes it worse for the vast majority of users. Also, to imply that the most effective measure that would help completely blind users is not useful for colorblind users is flat-out ridiculous; and unless you have legal training, your assessment that legal copyright concerns (which were the whole reason these maps were created, as existing copyright encumbered existing track map collections) are not an issue is reckless, and will be completely disregarded.

::::*Like I said, any very slight differences you see can be adjusted for. Something as simple as adding 1-2px to the width of each circle will more than make up for that tiny bit of darkening.  Also, the overall current color scheme is too dark for [[WP:CONTRAST]], so a new scale will lighten it up. Color-blind readers should not have to miss out on the experience of the image... telling them to "go read the prose" is damn insulting - we ''can'' make it so they can use the charts, and [[WP:COLOR]] says we ''must''.  As far as the font, ''like I said'', if what it takes is to free-hand draw the numbers 1 thru 5 using a brand-new, original design that you can release in the public domain, that will address ''all'' concerns about fonts. We don't even have to use numbers (though I think those are best) so long as each level is distinct without relying on color alone. -- [[User:Netoholic|Netoholic]] [[User talk:Netoholic|@]]  08:13, 5 August 2014 (UTC)
:::::*Hello, [[User:Netoholic]]. I think the addition of the numbers in the track map will make it harder to read, and as many people have already said, the important information in the track is always written '''in prose''' so I don't see why we need to change the track. About your accessible version, what symbols would you use for subtropical storms? What about extratropical storms and remnant low/invests?

::::::*I don't have any specific preference on what symbols to use, I'll leave that up to what is conventional in the meteorological space. All I am pointing out is that the current maps violate the MoS - "[[Wikipedia:Manual of Style/Accessibility#Color|Ensure that color is not the only method used to convey important information]]" - for no good reason. If these were simply track maps with no colors, this would not be a problem, but if you are going to use intensity scales for them, you can also accommodate the 8% of readers that have color vision problems. As a general suggestion, which I know people would object to vigorously, these maps should use line drawings, not satellite imagery, since the dark blue makes it even harder to discern the color differences and tend to obscure most ways of using graphical symbols on these charts (since black disappears against dark blue even for those with normal vision. -- [[User:Netoholic|Netoholic]] [[User talk:Netoholic|@]]  16:53, 8 August 2014 (UTC)

* To see how a colour blind person will view the images, goto http://www.color-blindness.com/coblis-color-blindness-simulator/.  Download the image from Wikipedia to be tested and then you will upload it to the web site.  Of the types listed on the website, Red-Blind/Protanopia, Green-Blind/Deuteranopia and Green-Weak/Deuteranomaly are the most common.
* The colours for tropical depression and tropical storm are very similar.  With the right kind of colour blindness, they look identical, thus they need to be changed.
* Putting colour blindness aside, personally, the image is confusing.  Nothing says what the colours mean. With the new media viewer, when you click on an image, you still get nothing.  More than colour dots need to be on the image.  At the very least, put a key on the image or do what the NWS does, put H, S, D in the dots.  Also, time wise, what do the dots mean?  Nowhere is that mentioned.  I don't think you need to put times on the images as the NWS does, but atleast mention that the dots are space out over 12hr intervals.

:Before I get off on a tangent, I don't think it's worth changing the td and ts colors (way too time consuming). Reality is we can't satisfy everyone, and I don't think it's the end of the world if those two look identical.  After all, a TD and TS are arguably fairly similar. As for your third point, that's fair and somewhat actionable, but in every TC article, there is a caption: "Map plotting the track and intensity of the storm according to the Saffir–Simpson hurricane wind scale".

We should do things that we know work for users, that we now don't upset or degrade accessibility for others etc. Too often we pick something, apply it everywhere and then someone is "well that's annoying". Information that is there should be accessible, but can be accessible in a less detailed way (as long as the user is aware that he is missing detail). Let's be honest, we are not a Hurricane institute distributing hurricane maps. If we were, then it would be important to communicate all the information in the method as accessible as in any way possible. But for an aggregated information wiki, annotating with for instance "a color coded" map of the phases of the storm already does a lot. If we can do the circle based indicators, then that also would help. Those are reasonable requests, for as long as editors are able to make those maps. If a volunteer is not able/willing to make contributions, because we are imposing accessibility requirements however, we have to think carefully about wether that is worth it in the grand scheme of things. We will never be fully accessible to everyone, but we should always strive to be the best that we can be.

== Location of Hurdat2 files for Eastern North Pacific Tropical Cyclones and Season Summary Maps ==

Hi,

I have installed the track map generator successfully on Mac OSX but I'm unable to fund the Hurdat2 files needed for generation of maps. I was able to create a track map of a 1928 cyclone using <code>./track --year 1928 --id 4</code> in the track directory which is one of the examples given on the project page, but Hurdat2 files are needed for generation of current cyclones. The Best Track Data at http://www.nhc.noaa.gov/data/#hurdat does not have 2016 data. Where can I find the files for 2016 cyclones?

On a another note, how are season summary maps created? Are they overlaid or do the Hurdat2 files contain information on all the storms?

== Add a Path Direction Indicator? ==

Please pass this suggestion along to the software developer:

:''Users may not be familiar with typical hurricane paths.  Consider adding some indication of the time sequence.''
:''Perhaps you could dim the connecting lines over time (white for the latest, dimming to a medium gray for the earliest).''

In the meantime, consider retrofitting the software's output image with some indication of direction.

== CMA/HKO BT? ==
So, recently I asked [[User:Meow]] that "can I use HKO/CMA estimates?" because IBTrACS lists HKO and CMA with their estimates. So, what is your opinion over this? {{ping|Supportstorm}} {{ping|Titoxd}} {{ping|Cyclonebiskit}} Regards, [[User:Nino Marakot|👦]] 07:37, 16 January 2020 (UTC)
:I would imagine that they could be used for CMA/HKO only storms, but as they aren't the RSMC for the Western Pacific I think it'd be better to use JMA data for the extratropical low/remnant low stages. &mdash; <span style="font-family:Helvetica;Arial; font-size:12px;">[[User:Iune|<span style="background:#D28574; color:#fff;padding:0 4px">Iune</span>]][[User talk:Iune|<span style="background:#E6A77D;padding:0 4px; color:#fff;"><i>talk</i></span>]]</span> 16:46, 16 January 2020 (UTC)

:::{{ping|Iune}} Maybe we can use them because IBTRACS lists their storm type as TS (tropical) when the CMA and/or HKO monitors the storm (for example, 1998 typhoon season's TD 09W is being tracked by CMA earlier than JTWC's BT and the IBTRACS considers them as TS).

::::::Iune I was going to bring up this with the project. I believe that the way IBTrACS is being used for track building is not consistent.

== No IBTrACS ==
Now, {{ping|Supportstorm}} recently changed tracks from IBTrACS to JMA/JTWC and OPC data, although it had a consensus that we can use IBTrACS data. My mind is (partially) blowing up from the situation, so what's your take, {{ping|Meow}} {{ping|Jason Rees}} {{ping|Iune}}? - Regards, [[User:Nino Marakot|👦]] 11:05, 6 March 2020 (UTC)
:{{Ping|Supportstorm}} informed me privately a couple of weeks ago that he prefers to use JMA/JTWC as well as OPC data for track maps rather than IBTRACS since they merge the tracks. I have no preference either way.[[User:Jason Rees|Jason Rees]] ([[User talk:Jason Rees|talk]]) 23:01, 6 March 2020 (UTC)
::I found some users, including myself, using IBTrACS to create tracks that were SYNTH with the available data. I went back and corrected a good chuck of the offending maps I created. Also only a few were leaving the map data in the codebox so it was difficult to verify which source was being used. I've been adding source tags to most of the data I've posted since about 2015 for this reason and highly encourage other track creators to do the same. Using JTWC as the primary data source, extending it with RSMC data is a good compromise so that tracks are consistent and everyone is on the same page. Also most users are going to look at JTWC or RSMC as a sources for data and it looks good for tracks to reflect the data we push in the articles. OPC data is valid for areas within their METAREA and is used operationally in the Atlantic or when an extra-tropical system moves out of the JMA's AOR. It's fine to use IBTrACS to pull agency data, but the merged track I don't think should be used. There's been inconsistencies with how they merge or favor data in the past. [[User:Supportstorm|Supportstorm]] ([[User talk:Supportstorm|talk]]) 07:02, 7 March 2020 (UTC)
:::{{ping|Supportstorm}} {{ping|Jason Rees}} So I can put it as 'we can use IBTrACS but we can't use their merged track because they have a past that there's been inconsistencies on how they merge or favor data'. I comprehend that as such.

::::But Supportstorm, you can only use and/or donate OPC tracks on codeboxes of such storms, so it's very difficult to use OPC data when we know that you manually do them and we don't know the secret. That's why I reached to you that 'can you put two weather charts with borders on kml format' because I'm gonna edit the contents of the format. As of now, you are not replied any link yet to the weather charts.

::::Also, I'm one of the users that doesn't leave whose agency track that were used, so I'm sorry about that. I'm currently recompiling tracks of JTWC and JMA data from 1945 to present, so thanks for the clarification.

::::Regards, [[User:Nino Marakot|👦]] 13:25, 9 March 2020 (UTC)
:::::I just wanna suggest that every user of the track generator should have a copy of Supportstorm's modified world map on the bg folder.

== Subtropical colors ==

{{ping|Hurricane Noah}} came to my Discord messages today and asked first, if I had the trackmaker (response was yes) and if I could change some dot colors (perhaps yes). I was then brought with the request to enact the following procedure:

Make "some dots" colored <span style="background-color: #D073FF;">this color (presumably SD)</span> and <span style="background-color: #69FF73;">this color (presumably SS)</span>— and to make them subtropical. I had some difficulty trying to work this out in coding the track.c file to make it happen (asked in WPTC discord in #general with no response to date.)

Soon in the WPTC discord, in #irc (where the IRC and Discord users intercommunicate), Noah mentioned suggesting new subtrop colors. I asked him his WP username so I could mention the colors and now we're here.

So...two things.

First, how would I code in the new colors? Currently, this is my modified "category define" part of track.c as-is:

<code>
 /* Purely by windspeed. */
  int winds[] = {
    0,
    34, 
    0 && (storm->maxtype == SUBTROPICAL), /*Subtropical.*/
    34 && (storm->maxtype == SUBTROPICAL), /*Subtropical.*/
    64, 
    83,
    96,
    114,
    136
  };</code>

Secondly, I propose myself two subtropical colors I've used in the past that were selected by a (i'm pretty sure) non-WP user:

<span style="background-color: #6e5cff;">SD</span> and <span style="background-color: #00fc8a;">SS</span>.

Thoughts for this?

== Please help? ==

According to other historical sources, a [[typhoon]] that originates to the south of Japan islands on 15-Jan-1960, passed by [[Iturup]] on 17-Jan (wind speeds at that time approached 12 on [[Beaufort scale]]). By 21-Jan the winds declined to 6-7 on [Beaufort scale. On 22-Jan, a different typhoon originating from the middle of Japan islands passed in the vicinity. 

Can you please help me identifying those two (I need their names and/or unique identifiers), and find the data about their tracks?

** I am fairly certain. The story is [[Self-propelled barge T-36]] and there are WAY more sources in Russian that I didn't bother copying to en-Wiki (go see the ruwiki page).

*** Unlike [[tropical cyclone naming|tropical systems]], which have a long history of formal designations, these sorts of blizzards and "non-tropical" storms don't really get any sort of standard names (unless someone happens to be familiar with such a practice in Russia/Japan).

Hey everyone, I want to discuss deploying a policy about what goes in track file descriptions. There have been a few complaints about users adding extra unnecessary commentary or nonsense messages when uploading new files. It would be beneficial if we could make a standard for what goes in the description. Most uploaders already follow the proposed policies, but it would be nice if we had a consensus.
# When uploading an updated operational version of the map include month/day and UTC time of the most recent track data, and, optionally in parentheses, other track map specific notes. Example: 11/22 18Z (Final operational update)
# When uploading a best track map include the name of the agency the BT comes from. Examples: NHC TCR update, JTWC BT update
Some exemptions may include uploading a map at a higher resolution or basemap quality. Just stating what changes you are making to the map quality is fine.
Following these policies will help others keep track of map versions and other pertinent changes. Feel free to leave comments or suggest other policies. [[User:Supportstorm|Supportstorm]] ([[User talk:Supportstorm|talk]]) 19:37, 22 November 2020 (UTC)

== Map projected Blue Marble ==

I want to do a little fiddling around with some ideas related to the color RfC. I downloaded the generator so I could import Blue Marble into ArcMap, but it does not seem to have any coordinate system. Does the track map generator do its coordinates differently? Is there a coordinate system I could use, or would I have to georeference the raster manually? I was told {{u|Chlod}} might know about this. [[User:TornadoLGS|TornadoLGS]] ([[User talk:TornadoLGS|talk]]) 19:09, 31 May 2022 (UTC)

:@[[User:TornadoLGS|TornadoLGS]]: [[:File:Blue Marble 2002.png]] uses the [[Mercator projection]] to transform the spherical shape of the Earth onto a flat 2D rectangle. The coordinate {{coordinates|90|N|180|W}} is pixel (0, 0) on the map, and {{coordinates|90|S|180|E}} pertains to the most bottom-left pixel which is, in this case, (43200, 21600). Methods of calculating the respective coordinate for each point to and from  the projection can be easily found online.
:I'd suggest that you just use the color override trick I mentioned before than use ArcMap for this. Not only will you save time as you no longer have to reinvent the entire map-making process through ArcMap, but you'll also be using the same software we already use to generate maps (which avoids inconsistencies with dot size, line shape, etc.). <span style="background:#ffff55">'''''[[User:Chlod|Chlod]]'''''</span>&nbsp;<small style="font-size:calc(1em - 2pt)">([[User talk:Chlod|say&nbsp;hi!]])</small> 12:22, 1 June 2022 (UTC)

From [https://www.wis-jma.go.jp/d/o/FMEE/BUFR/Analysis/Cyclone/ BUFR files] released by the Météo-France Réunion (MFR), the suffix of identifiers is confirmed to be '''S''' (i.g. 01S for Ashley). <s>All future unnamed systems in this basin should follow the suit.</s> &nbsp;[[User:Meow|🐱]][[User talk:Meow|💬]] 03:26, 28 September 2022 (UTC)
:It may bring confusion with JTWC's designations. Use ''MFR [number] [year] path.png'' instead.&nbsp;[[User:Meow|🐱]][[User talk:Meow|💬]] 13:35, 27 March 2023 (UTC)
