QPQ: None required.

Overall: The mudflow hook (ALT1) is the best of the three: it is specific, dramatic, and clearly sourced in the article. The four landfalls hook (ALT2) is solid but less striking. The contraction of the wind field hook is valid, but probably too technical. --Iurii.s (talk) 15:31, 21 March 2026 (UTC)

@Iurii.s: I chosen the mudflow hook (ALT1). ~🌀Ampil ^{「💬 / 📝」} 01:14, 22 March 2026 (UTC)

@Ampil, Iurii.s, and Jasper Deng: I have pulled this post-promotion due to a need for copyediting. The current version is not presentable for the main page. It includes sentence fragments such as Heavy rainfall 225–330 mm (8.9–13.0 in) across Mindoro, Samar, Panay and southern portions of Luzon. and Maximum wind speed recorded with 10-minute sustained winds of 120 km/h (70 mph) in Sangley Point on September 30.. Several sentences do not start with appropriate capitalization, such as one drowned in Palayan. three drowned in Panay. Several sentences begin with digits (5 injured in Bukidnon province.; 3,900 homes in four other barangays are buried into deposits about 9 m (30 ft) deep.; 29 provinces and 28 cities were placed under a state of calamity by Philippine President Fidel V. Ramos.. Also: the preferred hook (ALT1) is unclear as written. The source says the mudflows were 18 feet high (aka deep); as written, it could be taken to mean 18 feet in length, which is unimpressive. This should be clarified. Once these are done, a promoter is welcome to move this back into a prep. Dclemens1971 (talk) 02:33, 6 April 2026 (UTC)

@Dclemens1971: Fixed.

I also rewrote ALT1 "... that Tropical Storm Sibyl caused mudflows up to 18 ft (5.5 m) high from the slopes of Mount Pinatubo in Cabalantian?" ~🌀Ampil ^{「💬 / 📝」} 05:24, 6 April 2026 (UTC)

@Ampil: Nearly all your revisions still contain grammar errors. For example, the last one does not comply with MOS:CASE (if at the beginning of a sentence, only the first part of a compound number phrase is capitalized). Also, MOS:TENSE requires those past events to be described using the past tense (thus "are buried" is not appropriate). Your first one still lacks a verb and is thus still not a complete sentence. "Into" is also the wrong preposition to use after "buried"; "under" is the correct word. Also, 120 km/h and 70 mph do not convert to each other; please fix (do not round direct observations).--Jasper Deng (talk) 06:02, 6 April 2026 (UTC)

@Ampil: More examples of blatant grammar errors from a cursory spot-check: "At 12:00 UTC on the same day, the JTWC reached peak intensity at 110 mph (180 km/h) and made fourth landfall Quezon province" – this is the wrong sentence subject, since winds are a property of the storm, not the JTWC, and additionally, "made fourth landfall Quezon province" is missing a preposition before "Quezon province" as well as an indefinite article or demonstrative pronoun ("its" for example) before "fourth"; "first monitored tropical disturbance" – missing indefinite article between "monitored" and "tropical". A less-serious but still outstanding issue is that metric units should go first, and 95 knots is 110 mph and 175 km/h, not 180. If these and all other grammar errors are not fixed, this article will not be eligible for DYK. Note WP:DYKTIMEOUT; don't let it take that long.--Jasper Deng (talk) 11:34, 6 April 2026 (UTC)

@Ampil: I didn't offer comprehensive edits, just examples; there's quite a bit more that needs to be done to get this article presentable. Dclemens1971 (talk) 10:58, 6 April 2026 (UTC)

@Dclemens1971: Their further attempts to edit have only been introducing additional grammar and other errors. I'm now strongly leaning towards outright rejecting this DYKN even though it's not at the point of timeout, since I do not see this not becoming a huge waste of time for me or other promoters/reviewers. What do you suggest?--Jasper Deng (talk) 18:59, 6 April 2026 (UTC)

@Jasper Deng: That's within discretion, although you can also leave it alone for improvements. You can also as the promoter, you are also not required to review/approve changes. I am pulling this from the "approved" list since it seems like more work remains to be done. @Ampil: please ping the original reviewer for this article when you've completed the necessary copyedits. Dclemens1971 (talk) 19:50, 6 April 2026 (UTC)

@Jasper Deng, Dclemens1971, and Iurii.s: Copyedit diffs: ~🌀Ampil ^{「💬 / 📝」} 06:57, 8 April 2026 (UTC)

@Ampil: I'm sorry, but this is nowhere near thorough. There are numerous locations where you wrote that "Sibyl upgraded to a..." which is, again, the wrong sentence subject. Sibyl is the object of "upgrade" and the subject should be an agency (JTWC, PAGASA, JMA, or sometimes HKO). An indefinite article is still missing before "peak pressure", and in any case, "minimum pressure" is a better term. "The tropical disturbance moving westward" is also not a complete sentence due to the incorrect usage of "moving"; "was" is needed before. Again, this is not an exhaustive list. Please run this article's text through a spelling and grammar program (like Word or Google Docs) and do not ping again until you have thoroughly fixed it all. If you again ping without having done so, I will declare this nomination fully failed and a DYK will need to wait until someone else brings it up to GA standards. It is not the job of the rest of us or the DYK process to coach you on basic spelling and grammar, so you need to take responsibility for that. Alternatively, you can recruit the services of another editor at WT:WPTC, as it is okay to have multiple editors share credit for a DYKN, but we cannot continue to have to repeatedly ask you to fix spelling and grammar. --Jasper Deng (talk) 18:50, 8 April 2026 (UTC)

@Ampil and Iurii.s: This is indeed on me for not cross checking you. I'm disappointed. There's a reason why I find myself fighting a never-ending battle when it comes to the most basic composition mistakes in tropical cyclone articles. Please do not ever let a DYKN get to this point again with such glaring errors. I had checked only the sourcing of the hook and the hook itself. Please ping me again when you have fixed those and other mistakes.--Jasper Deng (talk) 02:40, 6 April 2026 (UTC)

@Jasper Deng: The article has been extensively copyedited now. I could not spot any glaring mistakes afterward. It seems presentable now. 🪐Kepler-1229b | talk | contribs🪐 15:38, 27 April 2026 (UTC)

@Kepler-1229b: I believe you should get credit for this DYKN too, since this was a massive cleanup. There still remain things to fix: for example, what's the meaning of "developing slowly on its progression"? I think the last three words are simply superfluous, and I'm not sure "scaffolding" is a countable noun (so I don't think the plural "scaffoldings" is correct). Fix those and any other issues remaining and it should be good to go with you added as an additional credit.--Jasper Deng (talk) 21:16, 30 April 2026 (UTC)

@Jasper Deng: I'll get on it when I can. 🪐Kepler-1229b | talk | contribs🪐 21:48, 30 April 2026 (UTC)

I've cleaned the article up a bit more now. I can't seem to spot any more issues; if you do I would appreciate it greatly if you notified me. 🪐Kepler-1229b | talk | contribs🪐 21:54, 30 April 2026 (UTC)

@Kepler-1229b: It is now essentially presentable, though the "winds of 110 mph" statement needs qualification since there are three types of winds it could be: 1-minute sustained, 10-minute sustained, or gust (it's the first of the three in this case; please specify that).

Turning attention to the hook, ALT1 is the only one of the three that meets WP:DYKINT, but it needs rephrasing, since "18 m high" is ambiguous–maximum depth (which is what is meant), elevation drop, river stage? It and the article should be rephrased as a maximum depth. --Jasper Deng (talk) 19:53, 1 May 2026 (UTC)

I added "1-minute sustained" , since the JTWC uses 1-minute sustained winds. 18 m is not mentioned in the JTWC source as meters it shows "... 18-foot high lahars (mudflows) from the slopes of Mount Pinatubo ..." @Kepler-1229b: there's a remaining issue, Jasper said should be rephrased as a maximum depth. I'll suggest four other hooks:

ALT1a: ... that Tropical Storm Sibyl caused mudflows with a maximum depth of up to 18 ft (5.5 m) deep from the slopes of Mount Pinatubo in Cabalantian?

ALT1b: ... that Tropical Storm Sibyl caused mudflows with a maximum depth of up to 18 ft (5.5 m) high from the slopes of Mount Pinatubo in Cabalantian?

ALT1c: ... that Tropical Storm Sibyl caused mudflows with a maximum depth of up to 18 ft (5.5 m) deep on the slopes of Mount Pinatubo in Cabalantian?

ALT1d: ... that Tropical Storm Sibyl caused mudflows with a maximum depth of up to 18 ft (5.5 m) from the slopes of Mount Pinatubo in Cabalantian?

Also, the 1995 Annual Tropical Cyclone Report, using 1-minute sustained winds, was owned by the JTWC. ~🌀Ampil ^{「💬 / 📝」} 09:35, 3 May 2026 (UTC)

Pinging @Jasper Deng: ~🌀Ampil ^{「💬 / 📝」} 09:35, 3 May 2026 (UTC)

@Ampil: Please do not ping me so much; it will not make me respond faster. Your rewordings contain superfluous words. It can simply be reworded to "...caused mudflows up to 5.5 metres (18 ft) deep from the flanks of Mount Pinatubo?". --Jasper Deng (talk) 21:32, 4 May 2026 (UTC)

ALT1e: ... that Tropical Storm Sibyl in 1995 caused mudflows up to 5.5 metres (18 ft) deep from the flanks of Mount Pinatubo?

ALT1f: ... that in 1995, Tropical Storm Sibyl caused mudflows up to 5.5 metres (18 ft) deep from the flanks of Mount Pinatubo?

Since there are multiple TS Sibyl's, you should specify the year. After that I think I'd be comfortable approving, though since I now consider myself a reviewer, someone else will need to promote it.--Jasper Deng (talk) 05:32, 5 May 2026 (UTC)

The 1992 Sibyl was a very strong typhoon. The 1995 Sibyl was a severe tropical storm.^[1] There are two storms named Sibyl. I've specified the year (1995). ~🌀Ampil ^{「💬 / 📝」} 08:12, 5 May 2026 (UTC)

for only ALT1e and ALT1f. Kepler-1229b and Lost.in.space.ace (who did much of the other grammar fixes) will need to receive a dual credit. Promotion will have to be by someone else as I am essentially a reviewer now.--Jasper Deng (talk) 20:35, 5 May 2026 (UTC)
