Part of the 2024 Pacific typhoon season

Typhoon Toraji, known in the Philippines as Typhoon Nika, is an active tropical cyclone affecting the Philippines in early November 2024. It was the fourth tropical cyclone in a series to impact the northern Philippines, following Tropical Storm Trami, Typhoon Kong-rey, and Typhoon Yinxing, which had occurred a few days earlier. The twenty-third named storm and tenth typhoon of the annual typhoon season, Toraji, developed into a low-pressure area and later into a tropical depression north of Yap on November 8. It moved into the Philippine Area of Responsibility, and PAGASA named the depression Nika the following day. The Japan Meteorological Agency (JMA) then upgraded the system to a tropical storm, naming it Toraji. Satellite imagery shows that Toraji was undergoing rapid intensification, with a small system displaying an elongated, compact central dense overcast feature, measuring around 81–92 miles (130–148 km) in diameter. On November 10, the JMA upgraded the system to a typhoon, and the following day, Toraji made landfall on Dilasag, Aurora, on Luzon Island, before moving inland over mountainous terrain, resulting in significant weakening.

The JMA reported that this was the first time since records began in 1951 that Yinxing, Toraji, Usagi, and Man-yi had all occurred in November.[1] As the storm approached the northern Philippines, evacuation orders were issued for residents in 2,500 villages. PAGASA raised Tropical Cyclone Wind Signals for several areas, and classes were suspended in various regions due to the storm's effects. A red alert warning was issued for Aurora, while officials in Aurora and Isabela reported fallen trees and power lines as the main impacts, blocking major roads. At least two people were killed by the storm, while two others were reported missing.

The origins of Typhoon Toraji can be traced back to November 8, when the Japan Meteorological Agency (JMA) reported that a low-pressure area had formed 620 km (386 mi) north of Yap,[2] with satellite imagery showing an organizing low-level circulation center, obscured by flaring convection wrapping around its southern and western peripheries. Environmental analysis indicated a favorable environment for further development, with sea surface temperatures of 30–31 °C (86–88 °F), strong poleward outflow aloft, and low vertical wind shear.[3] At 18:00 UTC on the same day, the JMA classified the system as a tropical depression,[4] and it moved into the Philippine Area of Responsibility, where PAGASA named it Nika the following day.[5] At 06:00 UTC the same day, the JMA upgraded the system to a tropical storm named Toraji,[6] which the United States Joint Typhoon Warning Center (JTWC) later designated as 26W.[7] Satellite imagery shows that Toraji was undergoing rapid intensification, with a small system displaying an elongated, compact central dense overcast (CDO) feature, measuring around 81–92 miles (130–148 km) in diameter. A microwave imaging reveals a complete eyewall surrounding a small microwave eye feature, along with a deep convective band over the southern quadrant.[8]

Early the next day, the JMA upgraded it to a severe tropical storm as it moved west-northwestward, with formative bands wrapping tighter around the obscured low-level circulation.[9][10] At 09:00 UTC on that day, the JTWC upgraded the storm to a minimal typhoon, noting a more asymmetric CDO in the eastern quadrant.[11] Satellite imagery reveals a decrease in easterly vertical wind shear, with the CDO becoming more symmetric and building back over the low-level circulation center.[12] At 15:00 UTC on the same day, the JMA upgraded the system to a typhoon,[13] and the following day, Toraji made landfall on Dilasag, Aurora, on Luzon Island at around 8:10 AM PHT (00:10 UTC),[14] before moving inland over mountainous terrain, which caused significant weakening.[15] Toraji emerged over the South China Sea off the coast of Magsingal, Ilocos Sur later that evening.[16]

Preparations

[edit]
Four simultaneously active tropical cyclones on November 11. From left to right: Yinxing, Toraji, Usagi, and Man-yi, the first occurrence since 1951

PAGASA warned of intense to torrential rains in the Cordillera Administrative Region and Cagayan Valley.[17] It also issued Tropical Cyclone Wind Signal No. 1 for the rest of Cagayan, including the Babuyan Islands, Apayao, Abra, Ilocos Norte, Ilocos Sur, the rest of Pangasinan, La Union, the rest of Benguet, the rest of Aurora, Tarlac, the northern and central portions of Zambales, the rest of Nueva Ecija, Pampanga, Bulacan, Metro Manila, Rizal, the eastern portion of Laguna, the eastern portion of Quezon (including Polillo Islands), Camarines Norte, Camarines Sur, Catanduanes, and Albay.[18] Signal No. 2 was upgraded for the northern portion of Aurora, Isabela, Quirino, the southern portion of mainland Cagayan, Nueva Vizcaya, the southern portion of Apayao, Abra, Kalinga, Mountain Province, Ifugao, Benguet, the northern portion of Nueva Ecija, the southern portion of Ilocos Sur, La Union, and the northeastern portion of Pangasinan.[19] After Toraji intensified into a severe tropical storm, PAGASA raised Signal No. 3 for the southeastern portion of Isabela and the northern portion of Aurora, indicating an expected wind speed of 89–117 km/h (55–73 mph) within the next 18 hours.[20] On November 11, the entirety of Kalinga, Mountain Province, the central and southern portion of Abra, Isabela, the northernmost portion of Aurora, northern and central portions of Ilocos Sur, and the northern portion of Ifugao, were upgraded to Signal No. 4, showing an expectation of winds of 89–117 km/h (55–73 mph).[21] A gale warning was also issued for the coasts of eastern and northern Luzon.[22]

With the storm approaching the northern Philippines, evacuation orders were issued for residents in 2,500 villages[23] affecting at least 8,000 people.[24] A red alert warning has been issued for Aurora.[25] Classes have been suspended in various areas due to the effects of the storm.[26] DILG Secretary Jonvic Remulla ordered all local government units threatened by Toraji to implement mandatory evacuations.[27] The La Union Provincial Disaster Risk Reduction and Management Office has began deploying some of the 16 teams prepared for the storm,[28] while President Bongbong Marcos has instructed the DPWH and DOTr to assist in positioning trucks and machinery from their private partners in areas along the path of Toraji.[29] The Magat, Ambuklao and Binga Dams opened spillways as a precaution.[30] An alarm was raised in Tuguegarao after water levels along the Cagayan River rose due to heavy rainfall.[31] The Metropolitan Manila Development Authority suspended number coding in Metro Manila as well as the Pasig River Ferry Service on November 11.[32] A total of 32,000 people were evacuated due to the storm.[33] At least 5,220 people were evacuated in Isabela, while 5,244 others were evacuated in Aurora,[34] and 482 in Nueva Vizcaya[35] Around 40,000 people were evacuated in Cagayan.[36] The Philippine Coast Guard's branches in the Ilocos Region and Cagayan Valley were placed on alert.[37]

Elsewhere

[edit]

In Hong Kong, the HKO raised the Standby Signal number 1 at 10.20 PM on November 11 followed by a Signal 3 at 2.40pm on November 13,[38][39] followed by Macau’s SMG at 12.30 AM the next day on November 12.[40]

Impact

[edit]

Officials in Aurora and Isabela reported that the main impact appeared to be fallen trees and power lines, which blocked major roads[41] and at least 22 bridges.[42] The mayor of Dilasag said that damage to agriculture in the town had reached “80 to 90 percent”.[43] Several bridges and roads in Cagayan and Quirino were also closed,[44] along with 17 sections of road in the Cordillera Administrative Region.[45] A rice field in Cordon, Isabela, was submerged by floodwaters caused by the storm.[46] In Romblon, the roll-on/roll-off passenger vessel MV Maria Oliva ran aground, and 156 people were rescued.[47] Nearly 700 people were stranded in ports directly affected by the typhoon.[48] Two people went missing after being carried away by strong currents in Amulung, while two people died after being electrocuted in separate incidents in Echague and Santa Ana, Cagayan.[49][50] Power outages affected 29 cities and municipalities.[33] Four houses in Baggao were destroyed, while other areas in Cagayan were flooded after water levels along the Cagayan River reached 11.2 m (37 ft),[51][52] about 4 m (13 ft) above normal. Knee-deep flooding also occurred in Santiago, Isabela.[36]

As of November 12, 2024, the National Disaster Risk Reduction and Management Council (NDRRMC) reported that 153,643 people in five regions were affected, with 17,070 displaced from their homes.[53]
