Part of the 2024 Pacific typhoon season

Typhoon Yinxing, known in the Philippines as Typhoon Marce, is an active and strengthening tropical cyclone that is threatening the Philippines in early November 2024. It will be the third tropical cyclone in a series to impact the northern Philippines, following Tropical Storm Trami and Typhoon Kong-rey a few days earlier. The twenty-second named storm and the ninth typhoon of the annual typhoon season, Yinxing, which refers to the Chinese term for the ginkgo tree, developed from an area of convection 494 km (307 mi) east of Yap. On November 3, the Japan Meteorological Agency (JMA) upgraded the system to a tropical storm named Yinxing, as it exhibited improved convective banding tightly wrapping around the obscured low-level circulation center. Microwave imaging showed the development of a nascent microwave eye as the storm moved west-northwestward along the southwestern edge of a mid-level subtropical high, driven by a strong northeasterly surge through the Luzon and Taiwan Straits, while deep convection persisted despite moderate southwesterly vertical wind shear.

A red alert warning has been issued for Cagayan and Batanes as PAGASA cautioned of heavy rains, strong winds, and storm surges impacting northern Luzon. The Department of National Defense has directed local authorities to forcibly evacuate residents from isolated areas, while classes have been canceled in various regions of Luzon due to Yinxing. Additionally, more than 200 passengers have been affected by flight cancellations.

Typhoon Yinxing emerged from an area of convection 494 km (307 mi) east of Yap, with satellite imagery showing the lower-level winds beginning to consolidate as the convective banding wraps around the low-level circulation center on November 2.[1] At 00:00 UTC the following day, the Japan Meteorological Agency (JMA) classified the system as a tropical depression,[2] and by 03:00 UTC, the United States Joint Typhoon Warning Center (JTWC) issued a tropical cyclone formation alert for the disturbance, citing a favorable environment for development characterized by low to moderate vertical wind shear, good divergence aloft, and warm sea surface temperatures of 29–30 °C (84–86 °F).[3] Later that same day, the JTWC designated the system as 24W, due to its compact structure and a small burst of deep convection occurring near the circulation center,[4] which revealed a nearly symmetrical and compact central dense overcast (CDO) with extremely cold cloud tops of −70 °C (−94 °F).[5]

At 18:00 UTC that same day, the JMA upgraded the system to a tropical storm named Yinxing,[6] as it exhibited improved convective banding tightly wrapping around the obscured low-level circulation center.[7] At 05:00 PHT on November 4 (21:00 UTC on November 3), Yinxing moved into the Philippine Area of Responsibility, where PAGASA named it Marce.[8] Microwave imaging revealed the development of a nascent microwave eye as Yinxing moved west-northwestward along the southwestern edge of a mid-level subtropical high,[9][10] with the system being very compact and displaying a symmetrical and persistent CDO that obscured the circulation center.[11] Early the next day, both the JMA upgraded it to a severe tropical storm, and the JTWC classified it as a minimal typhoon.[12] Yinxing continued to slowly intensify in the Philippine Sea, with feeder bands wrapping more tightly into a symmetrical CDO and producing overshooting cloud tops.[13] A pinhole eye also began to form, prompting the JMA to upgrade it to a typhoon at 00:00 UTC on November 5.[14] The typhoon was slowly consolidating, featuring a 115 miles (185 km) diameter CDO and a developing, ragged eye,[15] while microwave imagery revealed a strong northeasterly surge through the Luzon and Taiwan Straits,[16] with deep convection continuing to prevail despite the moderate southwesterly vertical wind shear.[17]

Preparations and impact

[edit]
Yinxing approaching the Philippines on November 4

PAGASA warned of heavy rains, strong winds, and storm surges affecting northern Luzon.[18] On the evening of November 4, PAGASA issued Tropical Cyclone Wind Signal No. 1 in Batanes, mainland Cagayan, the Babuyan Islands, Isabela, Apayao, Ilocos Norte, Ilocos Sur, La Union, Abra, Kalinga, Mountain Province, Ifugao and in parts of Pangasinan, Benguet, Nueva Vizcaya, Quirino and Aurora.[19] Beginning on November 5, PAGASA began raising Signal No. 2 over Batanes, Ilocos Norte and Kalinga as well as parts of Cagayan, Isabela, and Apayao. On November 6, Signal No. 3 began to be raised in parts of northeastern Cagayan, the Babuyan Islands and northern Apayao.[20]

The Department of National Defense ordered local authorities to forcibly evacuate residents of isolated areas.[21] Classes in various regions of Luzon have been canceled due to Yinxing, while more than 200 passengers have been affected by flight cancellations.[22][23] The Armed Forces of the Philippines announced that it has prepositioned 305 search, rescue, and retrieval teams in anticipation of the effects of Yinxing.[24] President Bongbong Marcos ordered all government agencies to be on high alert.[25] The Office of Civil Defense estimated that up to 24 million people could be impacted by Yinxing.[26] A red alert warning has been issued for Cagayan and Batanes.[27] Telecommunications company Globe Telecom prepared emergency supplies and personnel in areas where the storm was expected to hit.[28] Several people were evacuated in Cagayan, with officials noting that Yinxiang was the fourth storm to hit the province within the previous month.[29]

In Taiwan, the Central Weather Administration warned that Yinxiang could bring heavy rains in the east of the island, as well as in Keelung and Yilan County from 7 to 9 November.[30]
