Typhoon Yagi, known in the Philippines as Severe Tropical Storm Enteng, is an active and rapidly intensifying tropical cyclone that affected the Philippines in early September 2024. The eleventh named storm of the annual typhoon season. Yagi formed as low-pressure area late on August 30 to the northwest of Palau. Early on September 1, the Philippine Atmospheric, Geophysical and Astronomical Services Administration reported that the low-pressure area had intensified into a tropical depression and assigned it the name Enteng. The depression strengthened into a tropical storm a few hours later and was named Yagi by the Japan Meteorological Agency. It head northwestward as it made its first landfall over Casiguran, Aurora on September 2. It moved further inland into Luzon island and weakened due to the rugged terrain of the Cordillera Central before emerging over the South China Sea, where it reintensified and became a typhoon.

Yagi enhanced the southwest monsoon, causing severe flooding that led to at least 15 dead, 18 injured and 21 missing people, with total damage estimated at ₱351.2 million (US$7.13 million). In response, wind signals were raised across the country.

The origins of Typhoon Yagi can be traced back to August 30, when the Japan Meteorological Agency (JMA) reported that a low-pressure area had formed approximately 540 km (330 mi) northwest of Palau.[1][2] The broad low-pressure area began to organize and developed into a tropical depression on August 31.[3] Deep convection activity became concentrated around a circulation center, which was in a favorable environment with excellent equatorward and poleward outflow and warm sea surface temperatures of 29–30 °C (84–86 °F).[4] On September 1, Philippine Atmospheric, Geophysical and Astronomical Services Administration declared the system a tropical depression and named it Enteng, as it formed within the Philippine Area of Responsibility.[5] At 03:00 UTC that day, the United States Joint Typhoon Warning Center (JTWC) issued a tropical cyclone formation alert due to its low-level circulation center becoming well-defined with formative banding in its northern quadrants.[6]

A few hours later, the system was classified as tropical depression 12W, exhibiting a rapidly consolidating low-level circulation, a compact central dense overcast (CDO), and deep convective banding over the western semicircle; it then intensified into a tropical storm and was named Yagi by the JMA.[7][8] Yagi then shifted northwestward along the southwestern edge of a mid-level subtropical high,[8] which caused its convection to be sheared to the north and left the low-level circulation center exposed.[9] As the system progressed up the coast of Luzon island, the colder cloud tops in the CDO continued to expand,[10] and at 2:00 PHT (06:00 UTC) on September 2, the storm made landfall in Casiguran, Aurora.[11] Over the past six hours,[12] Yagi moved further inland into Luzon and weakened as it interacted with the rugged terrain of the Cordillera Central.[13] At 05:00 PHT on September 3 (21:00 UTC on September 2), it emerged over the South China Sea and began merging with a secondary circulation located west of Lingayen Gulf,[14] with Yagi's deep convection starting to wrap and develop convective bands extending to the west and south.[15] At around 06:00 UTC on September 3, the JMA reported that Yagi had intensified into a severe tropical storm due to warm sea surface temperatures and high ocean heat content.[16] Early the next day, both the JMA and the JTWC upgraded the storm to a minimal typhoon as an eye began to form on satellite imagery,[17] and Yagi started moving west-northwestward along the southwestern edge of a mid-level subtropical high,[18] with a pinhole eye developing as the typhoon underwent rapid intensification.[19]

Preparations

[edit]

Philippines

[edit]
Yagi passing through the Philippines on September 1

As the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) started to track Yagi (known as "Enteng" in the Philippines) as a tropical depression on September 1, Tropical Cyclone Wind Signal No. 1 was raised in Eastern Visayas; some parts of Bicol Region; eastern portions of Cagayan and Isabela; southern portions of Quirino and Nueva Vizcaya, and northern Quezon.[20] Shortly after Yagi became a tropical storm, PAGASA raised Signal No. 2 for the northeastern portion of Camarines Sur, the entire province of Abra; Apayao; Babuyan Islands; Cagayan; Ilocos Norte; Ifugao; Isabela; Kalinga; Mountain Province; Polillo Islands; and Quirino, and northern portions of Aurora; Camarines Norte; Ilocos Sur; and Nueva Vizcaya. The agency also added Benguet; La Union; Nueva Ecija; Rizal; Laguna; Marinduque, some parts of Batangas; Bulacan; Pampanga; and Pangasinan, as well as Metro Manila to Signal No. 1 because of gusty winds and heavy rains caused by the storm.[21] By September 4, most TCWS signals were lowered by the PAGASA as the storm left the Philippine Area of Responsibility.[22]

Classes in Metro Manila and multiple provinces across Luzon and the Visayas were suspended on September 2 and 3.[23][24] Several domestic flights to Bicol, Cagayan Valley, Mimaropa, the Visayas and Zamboanga Peninsula were also cancelled at Ninoy Aquino International Airport, while operations at six regional airports were suspended.[25] Forced evacuations were ordered in Naga, Camarines Sur.[26] An evacuation advisory was raised for the Marikina River after water levels reached 16 meters.[27] Salvage operations for the MT Terranova, which sank in Manila Bay and caused an oil spill during Typhoon Gaemi (locally called Carina) in July, were also suspended.[28] The Premier Volleyball League postponed the championship match of its 2024 Reinforced Conference originally scheduled on September 2.[29]

Hong Kong and Vietnam

[edit]

On September 3, the Hong Kong Observatory issued a Standby Signal No.1 warning over Hong Kong as Yagi approaches the city.[30] In Vietnam, authorities advised against fishing in hazardous waters, organizing outdoor gatherings, and advised strengthening home defenses and inspecting dykes, particularly at landing sites.[31]

Impact

[edit]

Philippines

[edit]

Yagi, combined with the effects of the southwest monsoon, resulted in 15 deaths, 15 injuries and 21 missing people. The National Disaster Risk Reduction and Management Council reported that 1,720,568 people were affected, with 88,077 displaced from their homes. The estimated agricultural damage was at ₱350.85 million (US$7.12 million),[32] while infrastructural damage amounted to ₱200,000 (US$4,060.91), for a total of ₱351.2 million (US$7.13 million).[33] Nine of the deaths occurred in Rizal.[34] Additionally, nearly 3,400 passengers were stranded in ports nationwide due to the storm.[35] 589 homes were affected, with 51 destroyed, and power outages were reported in 28 cities and municipalities.[33] Yagi caused flooding in Metro Manila,[36] and in the provinces of Bulacan,[37] Camarines Norte,[38] Camarines Sur,[39] Cavite,[40] Laguna,[41] Northern Samar,[42] and Rizal.[43] In Manila Bay, several ships ran aground off the coast of Navotas, while two others collided with each other, causing a fire on one of the vessels.[44] The Department of Agriculture estimated 13,623 hectares (33,660 acres) hectares of agricultural land, corn, and crops, to be affected by the storm.[45]

Across the Philippines, roads were blocked in 79 places and 19 bridges were rendered impassable by floods, landslides, and rockslides.[33] A barge also ran aground in Rosario, Cavite.[46] In Metro Manila, Calabarzon, and Bulacan, around 28,000 people lost electricity.[47] A state of calamity was declared in Naga, Camarines Sur and Allen, Northern Samar due to floods caused by Yagi.[48][49] The Department of Social Welfare and Development reports that assistance and relief goods worth ₱700 million (US$14.21 million) have been distributed to affected families.[50] The Government Service Insurance System prepared emergency loan programs for calamity-hit individuals.[51] Despite Yagi moving farther from the Philippine Area of Responsibility, the trough associated with it continued to bring rainfall to Northern Luzon.[52] On September 4, President Bongbong Marcos conducted aerial inspections of La Mesa Dam, Marikina, and Antipolo,[53] announcing that over ₱1.6 million (US$32,487.31) in humanitarian aid has been allocated to the hardest-hit areas.[54]

Vietnam

[edit]

In Ho Chi Minh City, several trees were uprooted, injuring three people. Some roofs were blown off along with some electric poles in Bình Dương province, causing power outages in some areas.[55]
