Severe Tropical Storm Kompasu, known in the Philippines as Severe Tropical Storm Maring was a very large and deadly tropical cyclone that affected the Philippines, Taiwan, and southeast China in early October 2021. Part of the 2021 Pacific typhoon season, Kompasu originated from an area of low pressure east of the Philippines on 6 October 2021. The Japan Meteorological Agency (JMA) classified it as a tropical depression that day. A day later, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) classified it as a tropical depression, naming it Maring. The cyclone was initially heavily disorganised, competing with another vortex, Tropical Depression Nando. Eventually, Maring became dominant, and the JMA reclassified it as a tropical storm, naming it Kompasu. Kompasu made landfall in Cagayan, Philippines, on 11 October 2021, and two days later, the storm made landfall in Hainan, China. The cyclone dissipated on 14 October 2021 while located over Vietnam.

The storm impacted many areas previously affected by Tropical Storm Lionrock a few days prior. Kompasu killed 46 people and 21 others were missing, majority of them were in the Philippines. The country also reported a damage of ₱8.3 billion (US$163 million). Total damage caused by the storm was US$545 million.

Meteorological history

At 18:00 UTC (Coordinated Universal Time) on 6 October 2021, the JMA noted that an area of low pressure embedded within a large monsoonal circulation had formed to the north of Palau.{{Cite web |date=6 October 2021 |title=JMA Warning and Summary 061800 |url=https://www.wis-jma.go.jp/d/o/RJTD/Alphanumeric/Warning/Warnings_and_weather_summary/20211006/180000/A_WWJP27RJTD061800_C_RJTD_20211006203004_82.txt |archive-url=https://archive.today/20211007040009/https://www.wis-jma.go.jp/d/o/RJTD/Alphanumeric/Warning/Warnings_and_weather_summary/20211006/180000/A_WWJP27RJTD061800_C_RJTD_20211006203004_82.txt |archive-date=7 October 2021 |access-date=7 October 2021 |publisher=Japan Meteorological Agency |location=Tokyo, Japan |url-status=live }} The system developed into a tropical depression at 00:00 UTC of the next day.{{Cite web |date=7 October 2021 |title=JMA Warning and Summary 070000 |url=https://tgftp.nws.noaa.gov/data/raw/ww/wwjp27.rjtd..txt |archive-url=https://archive.today/20211007035848/https://tgftp.nws.noaa.gov/data/raw/ww/wwjp27.rjtd..txt |archive-date=7 October 2021 |access-date=7 October 2021 |publisher=Japan Meteorological Agency |location=Tokyo, Japan |url-status=live }} At 09:00 UTC (17:00 PHT) on 7 October, PAGASA issued its first bulletin for the depression, and assigned it the name Maring.{{Cite PAGASA|date=7 October 2021|name=Maring|type=tcb|no=1|category=TD|url=https://pubfiles.pagasa.dost.gov.ph/tamss/weather/bulletin/TCB%231_maring.pdf}}{{dead link|date=August 2023|bot=medic}}{{cbignore|bot=medic}} [https://archive.org/download/pagasa-21-TC13/PAGASA_21-TC13_Maring_TCB%2301.pdf Alt URL] The JMA also noted the persistence of another, nearby tropical depression to its Northeast, later named Nando.{{Cite web |date=7 October 2021 |title=JMA Warning and Summary 070600 |url=https://tgftp.nws.noaa.gov/data/raw/ww/wwjp27.rjtd..txt |archive-url=https://archive.today/20211007090201/https://tgftp.nws.noaa.gov/data/raw/ww/wwjp27.rjtd..txt |archive-date=7 October 2021 |access-date=7 October 2021 |publisher=Japan Meteorological Agency |location=Tokyo, Japan |url-status=live }} As it is embedded in the same monsoonal depression and due to its proximity, Nando began to merge with Maring, and therefore formed a very broad and large circulation at a diameter of 1900 km, beating Lekima of 2007 by 200 km.{{cite web|author=杉江勇次|date=22 October 2021|title=巨大な台風１８号は沖縄の南へ新たな熱帯低気圧も発生か|trans-title=The huge Typhoon No. 18 is on its way to Okinawa, new tropical storm begins to form.|url=https://news.yahoo.co.jp/byline/sugieyuji/20211009-00262345|url-status=live|access-date=21 October 2021|archive-date=21 October 2021|archive-url=https://web.archive.org/web/20211021174736/https://news.yahoo.co.jp/byline/sugieyuji/20211009-00262345}}{{Cite web|author=杉江勇次|date=8 October 2021|title=台風１８号は、まれにみる発生当初からの巨大な台風|trans-title=Storm No. 18 is one of the rarest and most massive storms since its formation.|url=https://news.yahoo.co.jp/byline/sugieyuji/20211008-00262213|url-status=live|access-date=2021-10-24|archiveurl=https://web.archive.org/web/20211026224849/https://news.yahoo.co.jp/byline/sugieyuji/20211008-00262213|archivedate=26 October 2021|website=Yahoo!ニュース|language=ja|quote={{lang|ja|今回の台風１８号は速報値ではありますが、発生時から直径１９００キロもの広大な強風域を持つ巨大な台風として生まれました。[...] これまで最も大きな強風域を持って発生した台風は２００７年台風１４号で、その大きさは直径１７００キロでしたから。}} ["Although data on Typhoon No. 18 comes from a preliminary report, it is said to have been born with a large wind field of 1,900 kilometers in its initial formation.

Around 2,000 people were evacuated as a precaution. On 12 October, the governments of Baguio, Ilocos Sur, and Pangasinan cancelled school and suspended work in government offices. According to the National Disaster Risk Reduction and Management Council (NDRRMC), the storm affected 1,203,448 people in the regions of Ilocos, Cagayan Valley, Central Luzon, Calabarzon, Mimaropa, Caraga, Western Visayas, and the CAR. The Department of Public Works and Highways reported that 15 national roads and highways nationwide were impassable due to flooding attributed to Maring (Kompasu) and Tropical Depression Nando. The NDRRMC reported that a total of 42 people died, 16 people were still missing, and five people were injured.{{Cite report |url=https://reliefweb.int/report/philippines/ndrrmc-situational-report-tc-maring-2021-final-report-severe-tropical-storm-maring-april-05-2022-0800-am |title=Final Report for Severe Tropical Storm "MARING" |date=5 April 2022 |publisher=ReliefWeb |access-date=15 April 2022}}{{Cite news |date=12 October 2021 |title=Severe Tropical Storm Maring displaces thousands in 4 regions – NDRRMC |publisher=CNN Philippines |url=https://www.cnnphilippines.com/news/2021/10/12/Maring-damage-affected-people-.html |access-date=12 October 2021 |archive-date=12 October 2021 |archive-url=https://web.archive.org/web/20211012013849/https://www.cnnphilippines.com/news/2021/10/12/Maring-damage-affected-people-.html |url-status=dead }} Of the dead, nine people died in landslides in Benguet and five died in flash floods in Palawan.{{Cite news |date=12 October 2021 |title=At least 9 dead, 11 missing as storm Maring exits Philippines |publisher=BusinessWorld |url=https://www.bworldonline.com/at-least-9-dead-11-missing-as-storm-maring-exits-philippines/ |access-date=12 October 2021 |archive-date=12 October 2021 |archive-url=https://web.archive.org/web/20211012173559/https://www.bworldonline.com/at-least-9-dead-11-missing-as-storm-maring-exits-philippines/ |url-status=live }} In La Trinidad, Benguet, three children died after a mudslide buried their home.{{Cite news |last=Punongbayan |first=Michael |date=12 October 2021 |title=Maring Exits PAR, Leaves 9 Dead, 11 Missing |work=The Philippine Star |url=https://www.philstar.com/headlines/2021/10/13/2133722/maring-exits-par-leaves-9-dead-11-missing |access-date=12 October 2021 |archive-date=12 October 2021 |archive-url=https://web.archive.org/web/20211012224918/https://www.philstar.com/headlines/2021/10/13/2133722/maring-exits-par-leaves-9-dead-11-missing |url-status=live }} In Cagayan, power outages were reported.
