Tropical Depression Amang (2019)

{{Storm path|Amang 2019 track.png}}

The origin of Amang can be traced back to January 3, as an area of convection about {{convert|530|km|mi|abbr=on}} southeast of Kwajalein Atoll. The center was broad, asymmetrical, and poorly defined. Despite that, low wind shear, good poleward outflow, and high sea surface temperature of {{convert|28|–|30|C|F|abbr=on}} favoured potential tropical cyclogenesis.{{cite web|url=https://twtybbs.com/thread-17512-1-1.html|script-title=zh:01W JMA:GW 遠洋低緯西行 於菲中群島滯留飄移|trans-title=01W JMA:GW (Gale Warning), moved westward in low latitude, and drifted slowly in the Philippine Archipelago|work=Joint Typhoon Warning Center|via=Taiwan Typhoon BBS|date=January 3, 2019|access-date=January 13, 2019|archive-url=https://web.archive.org/web/20190113000531/https://twtybbs.com/thread-17512-1-1.html|archive-date=January 13, 2019|url-status=live}} On the next day, deep convection persisted over the northern part of the center while moving slowly to the north, which led to the issuance of Tropical Cyclone Formation Alert (TCFA) from the Joint Typhoon Warning Center (JTWC).{{cite web|url=https://www.metoc.navy.mil/jtwc/products/wp9019web.txt|title=Tropical Cyclone Formation Alert (Invest 90W)|work=Joint Typhoon Warning Center|date=January 4, 2019|access-date=January 23, 2019|archive-url=https://www.webcitation.org/75d5mATGu?url=http://www.metoc.navy.mil/jtwc/products/wp9019web.txt|archive-date=January 23, 2019|url-status=dead}} Later that day, the JTWC designated the system as Tropical Depression 01W.{{cite web|url=http://gwydir.demon.co.uk/advisories/WTPN32-PGTW_201901042100.htm|title=Tropical Depression 01W (ONE) Warning Nr 01|work=Joint Typhoon Warning Center|date=January 4, 2019|access-date=January 7, 2019|archive-url=https://www.webcitation.org/75FLiLfG3?url=http://gwydir.demon.co.uk/advisories/WTPN32-PGTW_201901042100.htm|archive-date=January 7, 2019|url-status=dead}} However, the convection was limited and the center cannot be identified, so the JTWC issued the final warning to the system on January 6.{{cite web|url=http://gwydir.demon.co.uk/advisories/WTPN32-PGTW_201901061500.htm|title=Tropical Depression 01W (ONE) Warning Nr 08|work=Joint Typhoon Warning Center|date=January 6, 2019|access-date=January 8, 2019|archive-url=https://www.webcitation.org/75GIMubDm?url=http://gwydir.demon.co.uk/advisories/WTPN32-PGTW_201901061500.htm|archive-date=January 8, 2019|url-status=dead}} Although some scattered deep convection burst, the center remained disorganized, and the tropical cyclone forecast models predicted that the syetem was unlikely to re-develop in days while it turned westward.

Within the next ten days, despite situating in warm waters of {{convert|28|–|30|C|F|abbr=on}}, low wind shear and strong diffluence, only scattered convection persisted over an ill-defined center, which made the re-development became unlikely. On January 18, the JTWC issued a TCFA again, as the center became well-defined, and deep convection burst over the western part of it. On January 19, the TCFA was cancelled, as the center was elongated and became partly exposed due to increasing wind shear. Nevertheless, the Japan Meteorological Agency (JMA) upgraded it to a tropical depression.{{cite web|url=http://tgftp.nws.noaa.gov/data/raw/ww/wwjp25.rjtd..txt|title=WWJP25 RJTD 190600 Warning and Summary at 0600Z January 19, 2019|work=Japan Meteorological Agency|date=January 19, 2019|access-date=January 19, 2019|archive-url=https://web.archive.org/web/20190119085114/http://tgftp.nws.noaa.gov/data/raw/ww/wwjp25.rjtd..txt|archive-date=January 19, 2019|url-status=dead}} Later that day, the PAGASA classified it as a tropical depression and assigned the local name Amang.{{cite report|url=https://ndrrmc.gov.ph/attachments/article/3585/Update_Severe_Weather_Bullettin_no_1_for_Tropical_Depression_Amang.pdf|title=Update Severe Weather Bulletin no 1 for Tropical Depression Amang|work=National Disaster Risk Reduction and Management Council|date=January 19, 2019|access-date=September 25, 2019|archive-url=https://web.archive.org/web/20190925052728/https://ndrrmc.gov.ph/attachments/article/3585/Update_Severe_Weather_Bullettin_no_1_for_Tropical_Depression_Amang.pdf|archive-date=September 25, 2019|url-status=live}} Amang turned north-northwest on the next day and made landfall over the Siargao Island at 20:00 PST (12:00 UTC).{{cite news|url=https://www.rappler.com/philippines/weather/221467-tropical-depression-amang-pagasa-forecast-january-20-2019-11pm/|title=Tropical Depression Amang makes landfall in Siargao|work=Rappler|date=January 20, 2019|access-date=December 15, 2024|archive-url=https://web.archive.org/web/20241215220644/https://www.rappler.com/philippines/weather/221467-tropical-depression-amang-pagasa-forecast-january-20-2019-11pm/|archive-date=December 15, 2024|url-status=live|url-access=registration}} It made another landfall in Salcedo, Eastern Samar at 07:30 PST January 21 (23:30 UTC January 20).{{cite report|url=https://pubfiles.pagasa.dost.gov.ph/pagasaweb/files/tamss/weather/tcsummary/201901%20AMANG.pdf|title=Tropical Cyclone Report: Tropical Depression Amang 19 – 21 January 2019|work=Philippine Atmospheric, Geophysical and Astronomical Services Administration|year=2019|access-date=December 14, 2019|archive-url=https://web.archive.org/web/20191214031222/https://pubfiles.pagasa.dost.gov.ph/pagasaweb/files/tamss/weather/tcsummary/201901%20AMANG.pdf|archive-date=December 14, 2019|url-status=live}} However, in the post-season analysis, the PAGASA revealed that the center of Amang actually remained offshore and never made landfall.{{cite report|url=https://pubfiles.pagasa.dost.gov.ph/pagasaweb/files/tamss/weather/tcsummary/PAGASA_ARTC_2019.pdf|title=Annual Report on Philippine Tropical Cyclones 2019|work=Philippine Atmospheric, Geophysical and Astronomical Services Administration|date=September 2021|page= |access-date=April 3, 2023|pages=41–45|archive-url=https://web.archive.org/web/20230403182415/https://pubfiles.pagasa.dost.gov.ph/pagasaweb/files/tamss/weather/tcsummary/PAGASA_ARTC_2019.pdf|archive-date=April 3, 2023|url-status=live}} The convection weakened and the center was completely exposed on January 22, due to increasing wind shear.

Amang was expected to hit the Bicol Region, while some areas were still recovering from the impacts brought by Usman last month.
