@ChessEric and Cyclonebiskit: There have been 2 sub-tropical storms named Alpha, one in 1972 and the one currently battering Portugal. Assuming it is ready to be moved to the main encyclopedia, I recommend moving this draft to Subtropical Storm Alpha (2020) and leave Subtropical Storm Alpha as a redirect to the disambiguation page Tropical Storm Alpha. Note that the disambiguation page also covers Subtropical Storm Alfa from 1975. davidwr/(talk)/(contribs) 20:40, 18 September 2020 (UTC)[reply]

I’ve been wondering, probably not though. Dougworld99 (talk) 01:05, 6 October 2020 (UTC)[reply]

@Dougworld99: Do you have a reliable source indicating that it did become fully tropical? TornadoLGS (talk) 01:37, 6 October 2020 (UTC)[reply]

No, just asking. Dougworld99 (talk) 02:32, 6 October 2020 (UTC)[reply]

@Dougworld99:Without a source, there is no rationale for mentioning the possibility of this being a tropical storm, and talk pages are not a forum to discuss meteorology. TornadoLGS (talk) 18:10, 6 October 2020 (UTC)[reply]

For the record, the Alpha TCR mentions nothing about it becoming fully tropical during its lifetime. Drdpw (talk) 21:39, 1 February 2021 (UTC)[reply]

Alpha was upgraded to 60kt on Feb 2021 TalephG (talk) 21:13, 1 February 2021 (UTC)[reply]

The 60kt wind speed occurred while the system was still extratropical. Its peak wind speed while a subtropical system was 45kt. Drdpw (talk) 21:28, 1 February 2021 (UTC)[reply]

This article is pretty well-written. Most of the remaining issues are largely grammar and wording issues. I've taken care of the problems with the references. LightandDark2000 🌀 (talk) 20:33, 14 May 2021 (UTC)[reply]

Lead

• to be classified as a subtropical cyclone as it approached the Iberian Peninsula, Add a comma after "subtropical cyclone".

Y Done. Hurricaneboy23 (page) * (talk) 21:02, 14 May 2021 (UTC)[reply]

• during the evening of 18 September and rapidly weakened as it moved over the mountainous terrain of Northeastern Portugal and was last noted on 19 September. There are two issues here. This sentence has grammatical errors, and it is also a run-on. Add a comma after "18 September". Also, delete "and" and split off the last part of the sentence into a new one. The new sentence should be something like "The system was last noted (or dissipated - take your pick) on 19 September".

Y Hurricaneboy23 (page) * (talk) 21:02, 14 May 2021 (UTC)[reply]

• At least two F1 tornadoes were confirmed in Portugal and one person was killed due to strong winds in Spain. Add a comma after "Portugal". Also, isn't F1 supposed to be EF1? The original Fujita scale fell out of use decades ago.

 Comment: The Enhanced Fujita scale is only used in the United States and Canada. All other countries still use the old one. Other part fixed. Hurricaneboy23 (page) * (talk) 21:02, 14 May 2021 (UTC)[reply]

• a majority of the damage occurring in Portugal. Add "with" after "a".

Y I'm assuming you meant before "a". Hurricaneboy23 (page) * (talk) 21:02, 14 May 2021 (UTC)[reply]

Yeah, that's what I had actually meant. :P LightandDark2000 🌀 (talk) 21:42, 14 May 2021 (UTC)[reply]

Meteorological history

• Alpha originated from a large, extratropical low-pressure area which developed over the Northeastern Atlantic Ocean on 14 September. Add a comma after "low-pressure area".

Y Hurricaneboy23 (page) * (talk) 21:14, 14 May 2021 (UTC)[reply]

• The low was initially very slow-moving, but began to dip southeastward and weaken by 15 September when the National Hurricane Center (NHC) first began to monitor the system for possible development into a tropical or subtropical cyclone as the system was expected to track close to a region of unusually warm sea surface temperatures to the west of Portugal of around 22 °C (72 °F), which would, however, still typically be too cold to support tropical cyclogenesis. This sentence is waayyy too long! Break it up into multiple smaller sentences. This revision would be better: "The low was initially very slow-moving, but began to dip southeastward and weaken by 15 September, when the National Hurricane Center (NHC) first began to monitor the system for possible development into a tropical or subtropical cyclone. This was because the system was expected to track close to a region of unusually-warm sea surface temperatures to the west of Portugal of around 22 °C (72 °F), though these temperatures would still typically be too cold to support tropical cyclogenesis."

• The size of the low's wind field continued gradually decreasing on 16 September as some of its frontal features gradually became less defined, although the NHC only highlighted a low (20%) chance of development at this time operationally. Add a comma after "16 September", and also after "this time".

Y Hurricaneboy23 (page) * (talk) 21:14, 14 May 2021 (UTC)[reply]

• became more concentrated and organized near the center of the low and a newly formed central low soon became the dominant feature within the larger extratropical system. Add a comma after "center of the low", and change "newly formed" to "newly-formed".

Y Hurricaneboy23 (page) * (talk) 21:14, 14 May 2021 (UTC)[reply]

• In post-season analysis, the NHC estimated that Alpha had formed as a subtropical storm at 06:00 UTC on 17 September as the thunderstorm activity associated with the smaller low feature became well-organized. Add a comma after "17 September". Also, you can change "had formed" to "had developed".

Y Hurricaneboy23 (page) * (talk) 21:14, 14 May 2021 (UTC)[reply]

• just about 225 nmi (259 mi; 417 km) off the coast of Portugal while the storm was producing 1-minute sustained winds up to 80 km/h (50 mph). Add a comma after "Portugal".

Y Hurricaneboy23 (page) * (talk) 21:14, 14 May 2021 (UTC)[reply]

• Alpha maintained its intensity up to its landfall about 11 mi (17 km) south of Figueira da Foz, Portugal around 18:40 UTC that day. Add a comma after "Portugal".

Y Hurricaneboy23 (page) * (talk) 21:14, 14 May 2021 (UTC)[reply]

• After landfall, the small low level circulation associated with Alpha began to quickly decay as the storm moved inland and the cyclone weakened to a subtropical depression at 0:00 UTC on 19 September. This sentence is a run-on. Add a comma after "quickly decay" and after "moved inland". Also, change "low level" to "low-level".

Y Hurricaneboy23 (page) * (talk) 21:14, 14 May 2021 (UTC)[reply]

• Alpha degenerated into a remnant low later that day as it moved over the mountainous terrain of Northeastern Portugal. Add a comma after "later that day".

Y Hurricaneboy23 (page) * (talk) 21:14, 14 May 2021 (UTC)[reply]

Preparations and impact

• orange warnings were raised by the Portuguese Institute of the Sea and Atmosphere (IPMA) due to the threat of high wind and heavy rain in the Coimbra and Leiria districts of Portugal. Add a comma after "(IPMA)".

Y Hurricaneboy23 (page) * (talk) 21:30, 14 May 2021 (UTC)[reply]

• Winds due to Alpha caused widespread power outages, fallen trees and damaged dozens of vehicles. Add a comma after "fallen trees".

Y Hurricaneboy23 (page) * (talk) 21:30, 14 May 2021 (UTC)[reply]

• at least two confirmed tornadoes of F1 intensity; See what I said above on the Fujita scale (in the lead).

Related to what I commented above. Hurricaneboy23 (page) * (talk) 21:30, 14 May 2021 (UTC)[reply]

• one near the town of Palmela which caused no reported damage and one in Beja which uprooted around 100 trees and damaged 30-40 vehicles. Run-on. Change to "one near the town of Palmela, which caused no reported damage, and one in Beja, which uprooted around 100 trees and damaged 30–40 vehicles". Use the special, longer dash, since this is a range.

Y Hurricaneboy23 (page) * (talk) 21:30, 14 May 2021 (UTC)[reply]

• Street flash flooding as a result of heavy rainfall became prominent in some cities in western Portugal where it was most severe in Setúbal. Add a comma after "flooding" and add a semicolon after "Portugal". Also, change "where it was most severe in" to "the flooding was the most severe in".

Y Fixed. Hurricaneboy23 (page) * (talk) 21:30, 14 May 2021 (UTC)[reply]

• Winds brought down a radio tower in Leiria and damage to it was described to be unrepairable. Add a comma after "Leiria". Also, change "the damage to it was described to be unrepairable" to "the radio tower was reported to have been damaged beyond repair".

Y Hurricaneboy23 (page) * (talk) 21:30, 14 May 2021 (UTC)[reply]

• Rain and windy conditions spread further inland into Spain while the remnants moved eastward. Add a comma after "Spain".

Y Hurricaneboy23 (page) * (talk) 21:30, 14 May 2021 (UTC)[reply]

• reported fallen trees and minor floods had occurred in the community during Alpha, while several water rescues were carried out during mid-day of 19 September. Change "reported" to "reported that". Also, change "during mid-day of 19 September" to "around midday on 19 September".

Y Hurricaneboy23 (page) * (talk) 21:30, 14 May 2021 (UTC)[reply]

• Alpha also caused lightning on Ons Island, which led to an isolated forest fire. Link lightning and forest fire.

Y Hurricaneboy23 (page) * (talk) 21:30, 14 May 2021 (UTC)[reply]

Records and distinctions

• Additionally, Cyclone Ianos was approaching its first landfall in Greece at the time and thus marked the first time in recorded history that two storms of subtropical or tropical nature impacted continental Europe simultaneously. Add a semicolon after "at the time", and change "and thus marked" to "this marked." Also, link Europe.

Sources

• I've fixed all of the issues that I found with the citations. Please note that all citations should be completely filled out. Also, each reference should use the same formatting.

These are all of the issues that I have found. The article is pretty well-done, but there are still a handful of (mostly minor) issues that need to be corrected. LightandDark2000 🌀 (talk) 20:33, 14 May 2021 (UTC)[reply]

Done! Hurricaneboy23 (page) * (talk) 21:30, 14 May 2021 (UTC)[reply]

Copyvio check

• I ran this article through Earwig's Copyvio Detection tool. There is a 27.3% match, but there isn't anything in the article that I would flag as an actual copyright violation. LightandDark2000 🌀 (talk) 21:42, 14 May 2021 (UTC)[reply]

There was a famous cyclone in the history of our country which was incredibly destructive, but there is no english version for this article. I'm not a climate scientist. I have no idea what a subtropical storm is and how it differs from a winter cyclone. Should this one be mentioned? https://pt.wikipedia.org/wiki/Ciclone_de_1941 — Preceding unsigned comment added by 2001:8A0:70D2:6C00:6DD3:54E6:690D:821C (talk) 20:40, 8 January 2022 (UTC)[reply]

No. That was an extratropical cyclone, while records of this storm pertain to subtropical and tropical cyclones. TornadoLGS (talk) 21:12, 8 January 2022 (UTC)[reply]
