Typhoon Yutu, known in the Philippines as Typhoon Rosita, was an extremely powerful tropical cyclone that caused catastrophic destruction on the islands of Tinian and Saipan in the Northern Mariana Islands, and later impacted the Philippines. It is the strongest typhoon ever recorded to impact the Mariana Islands, and is tied as the second-strongest tropical cyclone to strike the United States and its unincorporated territories by both wind speed and barometric pressure. It also tied Typhoon Kong-rey as the most powerful tropical cyclone worldwide in 2018. Yutu also affected the Marianas and the Philippines after Typhoon Mangkhut had caused extensive damage there in September.

The twenty-sixth named storm and the twelfth typhoon of the 2018 Pacific typhoon season, The originated as a low-pressure area moving westward on October 20, that became a tropical depression the next day, before strengthening further into a tropical storm on October 22, receiving the name Yutu from the Japan Meteorological Agency. Favorable conditions led to a period of rapid intensification, causing Yutu to become a typhoon as it moved west-northwestward on October 23, and by the next day, Yutu had achieved its peak intensity. An eyewall replacement cycle ensues, weakening Yutu, before making landfall over Tinian on October 25. Substantial outflow allowed the storm to re-strengthen, making it reach a secondary peak on October 26. As it approached the Philippines the following day, the PAGASA assigned it the local name Rosita, while it began to reach less favorable conditions. The storm made a second landfall over Luzon by October 29. Yutu then entered the South China Sea, where it continued to weakened while turning northward, until it had dissipated by November 3.

On October 20, the Japan Meteorological Agency (JMA) began monitoring a low-pressure area near 9°N 164°E / 9°N 164°E / 9; 164 moving westward.[1] Located 1,817 km (1,129 mi) east-southeast of Andersen Air Force Base in Guam, the disturbance was situated in an environment of favorable conditions for potential tropical cyclogenesis such as substantial equatorward outflow, low vertical wind shear, and very warm sea surface temperatures of 30–32 °C (86–90 °F). Within the system's center was an elongated surface circulation with deep atmospheric convection—or showers and thunderstorms—wrapping into it.[2] By 18:00 UTC, the JMA reported that the disturbance had intensified into a tropical depression around the Marshall Islands.[3] Eighteen hours later on October 21, the United States Joint Typhoon Warning Center (JTWC) designated the consolidating system 31W.[4] As the cyclone began to steer west-northwestward around a subtropical ridge to its southwest, radial outflow was limited by a weak tropical upper tropospheric trough (TUTT) cell to the system's northwest,[5] though it soon diminished the next day.[6] At 00:00 UTC of October 22, both the JMA and JTWC assigned the tropical depression a tropical storm, with the former giving it the name Yutu.[3][7]

Typhoon Yutu shortly before its secondary peak on October 26

The system expanded as favorable conditions continued to fuel it, with the most intense thunderstorms positioned to the east and south of the center.[8] Yutu significantly improved its structure, marking the beginning of a period of rapid intensification.[9] At 18:00 UTC, the JMA upgraded Yutu to a severe tropical storm, and six hours later on October 23, both the JMA and JTWC classified the storm as a typhoon.[3][7] As rainbands tightened toward the center, an eye became apparent on satellite imagery.[10] While being over a region of high ocean heat content, the eye became well-defined and expanded to 43 km (26 mi).[11] Although the eye soon shrunk, by early the next day, Yutu was classified a super typhoon by the JTWC.[12] By 12:00 UTC, the JMA and JTWC reported that Typhoon Yutu had attained its peak intensity, with the former estimating maximum sustained winds of 215 km/h (130 mph) and a barometric pressure of 900 hPa (26.58 inHg), and the latter estimating 1-minute sustained winds of 280 km/h (175 mph), making Yutu equivalent to a Category 5 hurricane on the Saffir–Simpson scale.[3][7]

Continuing northwestward, Yutu was positioned 56 km (35 mi) west-northwest of Saipan as it approached the island. Concurrently, cold cloud tops began to warm, signaling a weakening trend. Furthermore, microwave imagery revealed concentric eyewalls, indicating the onset of an eyewall replacement cycle.[13] Around 18:00 UTC (04:00 ChST of October 25), Yutu struck Tinian and the southern portion of Saipan at peak intensity,[14] becoming the most powerful storm on record to impact the Northern Mariana Islands.[15][16] The eastern periphery of the eyewall thinned under the influence of dry air in the middle troposphere,[17] while the storm maintained its robust convection around the cooling, shrinking eye.[18] The cycle was then completed, evident by a Special Sensor Microwave Imager/Sounder image.[19] The eye again became well-defined, as low easterly wind shear and excellent outflow persisted, despite an upper-level anticyclone restricting the outflow from the east,[20] and by 18:00 UTC of October 26, the JMA and the JTWC reported that Yutu had attained its secondary peak intensity; the JMA estimated winds of 195 km/h (120 mph) and a minimum barometric pressure of 915 hPa (27.02 inHg), and the JTWC gave Yutu the same estimate as the previous.[3][7]

Typhoon Yutu weakening west of Luzon on October 31

While over the Philippine Sea, Yutu crossed the 135°E boundary of the Philippine Area of Responsibility at 00:00 UTC of October 27, receiving the local name Rosita from the PAGASA—the national weather agency for the Philippines.[21] The storm then entered a marginal environment of high wind shear, despite substantial outflow and warm waters, as the eye became ragged.[22] Conditions then became slightly less favorable, with dry air wrapping into the storm's circulation; on this basis, the JTWC assessed that Yutu had weakened to below super typhoon strength on October 28.[23] While the storm was 713 km (443 mi) east-northeast of Manila, Philippines, rainbands began to collapse as the cloud tops warm, after outflow had reduce. Meanwhile, Yutu steered west-southwestward along the southern edge of the subtropical ridge.[24] During October 29, the eye became ill-defined and cloud-filled as weakening continued due to decreased outflow.[25] Between 20:00 UTC and 21:00 UTC, Yutu made landfall over Dinapigue, Isabela, Philippines, with winds of 139 km/h (86 mph) recorded by the PAGASA.[21] The JTWC, however, reported that Yutu had made landfall at 19:50 UTC. Deep convection around the symmetric storm continued to rapidly decay as Yutu tracked westward inland over the next day.[26] Despite this, the system was still organized as it began to emerge over the South China Sea,[27] though it weakened into a severe tropical storm at 06:00 UTC.[3]

As it continued to move away from the Philippines, the system re-consolidated as indicated by improved banding over the northern flank,[28] but weakened into a tropical storm at 18:00 UTC, according to the JTWC.[7] Exhibiting a partially-exposed center, Yutu moved northwestward along the subtropical ridge throughout October 31.[29] At 06:00 UTC, the JMA downgraded Yutu to a tropical storm.[3] Regardless, the system stockpiled convection over its southern half of the center. Moreover, moderate wind shear was subdued by strong poleward outflow, making conditions favorable for intensification.[29] By November 1, Yutu had briefly strengthened to near typhoon-force winds of 110 km/h (70 mph), according to the JTWC.[7] However, Yutu began experiencing moderate to high wind shear while turning northward due to outflow being limited elsewhere and cooled sea surface temperatures, as its center becomes poorly-defined and deep convection becomes displaced to the northeast.[30] By November 2, the JMA reported that Yutu had weakened into a tropical depression at 06:00 UTC.[3] The JTWC followed suit in downgrading the system six hours later,[7] after the storm had lost all of its convection from unfavorable wind shear while 287 km (178 mi) southeast of Hong Kong.[31] The JTWC reported that Yutu had degenerated into a tropical disturbance at 18:00 UTC,[7] whereas the JMA continued monitoring the system until it had dissipated the next day at 06:00 UTC.[3]

Preparations

[edit]

Mariana Islands

[edit]

On October 20, the National Weather Service (NWS) office in Tiyan, Guam released a Special Weather Statement on the pre-Yutu disturbance after a Tropical Cyclone Formation Alert from the JTWC was issued, stating that it could impact the Mariana Islands by midweek.[32] Two days later, the NWS instated a tropical storm watch for Rota and a typhoon watch on Saipan and Tinian.[33] As Tropical Storm Yutu continued towards the archipelago, tropical storm watches were added on Guam, Alamagan, Pagan, and Agrihan.[34] With forecasts stating that Yutu would become a typhoon, the watches for Saipan and Tinian were upgraded to warnings on October 23;[35] all tropical storm watches were upgraded to warnings later that day, and the typhoon watch for Rota was upgraded to a warning also.[36] In the month prior to Yutu, Typhoon Mangkhut struck the Mariana Islands, prompting emergency officials to stockpile supplies. With relief supplies largely unused, storage facilities on Guam had 220,000 liters of water and 260,000 meals readily available.[37]

Condition of Readiness (COR) 2 was hoisted in Rota, Saipan, and Tinian on October 23,[36] before it was upgraded to COR 1 the next day after Yutu had become a super typhoon on that day.[38] Governor Ralph Torres ordered all government offices to shut down in preparation of Yutu.[39] Additionally, Northern Marianas College campuses were closed on October 23.[40] The Chief Judge of the District Court, Ramona Villagomez Manglona, closed the federal court.[41] Attorney General Edward Manibusan warned retailers against price gouging.[42] Public schools canceled classes across the three main islands. Seven were used as shelter to accommodate 326 people;[43] some of them were filled quickly.[44] Hundreds of cars lined up at gas stations.[45] Federal Emergency Management Agency (FEMA) personnel deployed to both Tinian and Saipan ahead of the storm. U.S. President Donald Trump declared an emergency for the Northern Islands on October 24.[46] The Department of Fire and Emergency Medical Services in Saipan deployed a team in preparations.[47] All flights in the Northern Marianas were canceled, though the Saipan International Airport remained open. The Commonwealth Utilities Corp. shut its water distribution system to conserve water tanks.[48] Several businesses were closed, hotel constructions were suspended, and banks, restaurants, and other shops were boarded. Imperial Pacific suspended its casino. The United States Postal Service closed its offices in Saipan and Rota. United States Coast Guard ports were closed across Saipan, Tinian, Rota, as well as Guam.[49]

COR 2 was also hoisted in Guam,[38] before it was upgraded to COR 1.[50] Governor Eddie Baza Calvo declared a state of emergency in anticipation of the typhoon.[51] The Guam Department of Education closed all of its schools,[52] with eight of them turned into emergency shelters to accommodate nearly 2,200 people.[53] Catholic schools and charter schools were closed as well. St. John's School, the University of Guam, Guam Community College, and Harvest Christian Academy were also closed. The Guam Regional Transit Authority halted bus operations in response to the COR 2, and transit services were paused until two hours after COR 4—the normal Condition of Readiness. Banks were closed across the island, along with post offices, and all government agencies. The Legislature, Judiciary, and District Court were all closed as well. Guam Memorial Hospital, Guam Regional Medical City, and Naval Hospital Guam suspended all operations. Two Lovers Point and the War in the Pacific National Historical Park were closed.[52] Flights to and from Antonio B. Won Pat International Airport were canceled.[54] People were encouraged to report price gouging, as it was illegal when under COR 2, to the Office of the Attorney General.[55]

Philippines

[edit]
Highest Tropical Cyclone Wind Signal issued by the PAGASA for Yutu (Rosita)

On October 27, after Yutu (Rosita) had entered the Philippine Area of Responsibility, the PAGASA issued gale warnings across the northern and eastern seaboards of Luzon and the eastern seaboard of the Visayas, due to the enhancement of the northeast monsoon (Amihan) by Yutu. The agency also advised fishermen and others with small vessels to not sail in those areas, while those with larger vessels were advised to look out for big waves.[56] Starting October 28, the PAGASA began releasing Tropical Cyclone Wind Signals (TCWS) across regions of the Philippines; TCWS No. 1 was raised across 23 provinces in Luzon.[57] The following day, TCWS No. 2 was hoisted across Cagayan, Isabela, Aurora, Quirino, and Polillo Island, before it extended to Mountain Province, Ifugao, Benguet, and Nueva Vizcaya that same day. The signals for Isabela, Quirino, and the northern part of Aurora were raised to TCWS No. 3 along with Nueva Vizcaya and Ifugao. TCWS No. 3 was then raised across Benguet, La Union, Ilocos Sur, Mountain Province, and Pangasinan. An orange rainfall warning was issued across Bataan, Bulacan, Nueva Ecija, and Rizal, and extended to Pampanga, after Yutu had made landfall.[58]

Yutu was anticipated to make landfall after Typhoon Mangkhut (Ompong) had devastated the country in September.[59] About 32,519 people were pre-emptively evacuated from the Ilocos Region, Cagayan Valley, Central Luzon, and the Cordillera Administrative Region (CAR). 593 cities or municipalities across Ilocos Region, Cagayan Valley, Central Luzon, Calabarzon, the Bicol Region, CAR, and Metro Manila had classes suspended, and 193 across Ilocos, Cagayan Valley, and CAR suspended government work. 44 flights were canceled, with 38 domestic and 6 international. 2,267 passengers and 217 sea vessels were stranded while sheltering in the ports. The Department of Social Welfare and Development had stockpiled 376,330 family food packages and relief items worth ₱919.672 million (US$17.463 million). In total, about 155,242 people had moved to 1,388 evacuation centers.[58] While President Rodrigo Duterte visited areas previously affected by Mangkhut ahead of Yutu, he received complaints from local government unit officials that the Commission on Audit did not allow cash advancements for the procurement of building materials intended for the victims of Mangkhut.[60]

Hong Kong

[edit]

The Hong Kong Observatory (HKO) hoisted a No. 1 Standby Signal on October 31 as Yutu was 670 km (420 mi) southeast of the region. The next day while it was 370 km (230 mi) southeast, the agency raised a No. 3 Strong Wind Signal, the first in November since Typhoon Ira in 1993. As it weakened however, the signal was lowered to No. 1 on November 2, and was later cancelled that same day.[61]

Impact

[edit]

Mariana Islands

[edit]

Striking Tinian and Saipan on October 24 as a Category 5-equivalent super typhoon, Yutu became the strongest tropical cyclone to ever impact the Mariana Islands and the second-strongest to strike the United States or its territories as a whole, tied with Typhoon Karen in 1962 and Hurricane Camille in 1969.[62][63] Only the 1935 Labor Day hurricane impacted the country at a greater strength.[46] Yutu was the strongest storm to impact the Marianas since Typhoon Soudelor in 2015, and was the worst to do so since Typhoon Jean in 1968.[64] Meteorologist Brandon Aydlett at the NWS described the typhoon as "the storm which sets the scale for which future storms are compared to".[37] Total damage was estimated to reach over $800 million, according to FEMA.[65] The highest wind gust was recorded at 170 km/h (100 mph) over Saipan at 14:44 UTC on October 24, before weather instruments across the island along with Tinian were damaged or destroyed. Surface observations recorded maximum sustained winds of 270 km/h (170 mph) with wind gusts of 320 km/h (200 mph). A resident recorded gusts of 270 km/h (168 mph) and an anemometer recorded a peak wind of 214 km/h (133 mph). Though 68 mm (2.66 in) of rain was observed at Saipan International Airport, it was likely well below the actual rainfall. A rain gauge measured 250 mm (10 in) of rain, though it was 4.8 km (3 mi) northeast of Yutu's eye.[14]

Damage to a communication tower on Tinian after Typhoon Yutu

During the passage of Yutu, 133 people were injured, with 121 of them being related to the storm.[66] At least 1,000 structures were damaged or destroyed, including the power plants of Saipan and Tinian.[14] Yutu's eyewall also knocked out Saipan's doppler radar on October 25, during the storm's landfall.[16] The entirety of both islands were left without electricity; around 200 to 300 power poles were downed, 400 to 500 were leaning, and a large amount of transformers and conductors were downed as well. Some people were injured by glass and other debris.[67] Maximum coastal flooding in Saipan and Tinian were measured at 9.1 m (30 ft) and 6.1 to 7.6 m (20 to 25 ft) respectively.[68] Across the commonwealth, utility infrastructure was severely impacted, and over 500 homes were destroyed, rendering over 1,000 people homeless.[69] Cell towers were significantly damaged as well. Roads were inaccessible due to debris, in addition to ports.[70] The population of forest birds such as the golden white-eye, bridled white-eye, Mariana kingfisher, rufous fantail, and honeyeaters, was expected to decline as a result of the storm.[71] The typhoon killed two people in Saipan; a 44-year-old woman in Chalan Kanoa when it wrecked the building she was staying in, and another woman in Susupe who died of carbon monoxide poisoning caused by inhaling the fumes of a generator.[14]

The majority of buildings in southern Saipan lost their roofs or were destroyed,[67] including Hopwood Middle School, which suffered extensive damage,[72] and the gymnasium and classrooms of Northern Marianas College.[73] Cars were crushed under a collapsed garage in Saipan.[67] Four hotels were closed after sustaining significant damage.[74] Low-lying vegetation in southern parts of the island were shredded or ripped from the ground.[37] Saipan International Airport sustained significant damage; terminals flooded and navigation aids were rendered inoperable.[75] 462 homes were completely destroyed and 317 were severely damaged across Kagman, Lau Lau, Susupe, Chalan Kanoa, San Antonio, Koblerville, Dandan, and San Vicente.[69] Many cars had their windshield and windows shattered by debris. Powerful winds dragged a container and crashed it into two police cars behind the Department of Public Safety building in Susepe. Additionally, many trees were uprooted.[73] The majority of homes on Tinian were severely damaged or destroyed. Some concrete structures sustained significant damage, with a few completely destroyed, and residents reported that those buildings shook during the typhoon. Storm shutters were torn from windows, leaving the interior of structures exposed to wind and water damage. In one instance, a door was ripped from a building and hurled 30 m (100 ft) into a pigsty.[37] The island's only health center sustained major damage; however, no patients were being treated at the time.[46] Tinian International Airport suffered significant damage.[75] 70 homes were destroyed and 113 were severely damaged across the villages of San Jose, the House of Taga, Carolinas, Marpo Valley and Marpo Heights.[69]

Yutu brought typhoon-force winds over Rota, causing property and crop damage of $1 million each.[76] The island was without power, and 13 homes were destroyed and 38 were damaged across Songsong and Sinapalo.[69] Rota Airport received debris along its runway.[70] Guam endured tropical storm winds of 48–64 km/h (30–40 mph).[77] On October 25, Anderson Air Force Base recorded a gust of 93 km/h (58 mph), while the NWS office recorded a peak gust of 85 km/h (53 mph). The highest rainfall from Yutu in Guam was recorded in Dededo at 1 in (25 mm). Yutu caused property damage of $500,000, while crop damage was estimated at $250,000.[78] The Guam Power Authority reported power outages over some parts of the island,[79] and no major damage or injuries from Yutu were reported.[80] As such, Guam was placed in COR 4 on the same day.[81]

Philippines

[edit]

According to the National Disaster Risk Reduction and Management Council (NDRRMC), the storm killed 29 people and injured two others. A total of 567,691 people were affected across 19 provinces, and 438,895 had been displaced. About 66,165 homes were damaged, with 6,603 destroyed. 106 road sections and ten bridges were affected across Cagayan Valley, Central Luzon, and the Cordillera Administrative Region (CAR). About 51 transmission lines were affected by Yutu, leading to power outages throughout Luzon, though most power was quickly restored by October 31. The total amount of damage to agriculture was estimated at ₱2.904 billion (US$55.160 million), mostly towards rice. At least 11 landslides were reported across the island.[58] On October 29, both the highest wind gust of 130 km/h (81 mph) at 21:25 UTC and lowest sea-level pressure of 971.8 hPa (28.70 inHg) at 21:00 UTC were recorded at Casiguran, Aurora. Between 50 and 200 mm (2.0 and 7.9 in) of rain was estimated to have fallen over Northern Luzon, while 200 and 300 mm (7.9 and 11.8 in) of rain was estimated elsewhere in the island. As Yutu rapidly weakened, rainfall increased over the eastern side of Northern and Central Luzon, although surface observations suggested that orographic lifting had amplified the rainfall.[21] As the storm passed through Luzon, the Ambuklao and Binga Dams in Benguet, the Magat Dam near Cagayan River, and the San Roque Dam in Pangasinan all released water.[82]

The highest 24-hour rainfall was measured in Baguio at 170 mm (6.7 in) on October 30, while the highest rainfall throughout the storm duration was measured in the same city at 177.8 mm (7.00 in).[21] A total of 3,567 houses were damaged in the CAR. Most of the deaths occurred in Mountain Province, after 21 people died in Natonin when a landslide buried a Department of Public Works and Highways building. A rescuer also drowned trying to help victims of the landslide.[58] Roads were rendered impassable throughout the town as well.[83] Throughout the CAR, parts of Abra and Mountain Province and the entirety of Apayao, Benguet, Ifugao, and Kalinga all lost power. Seven landslides across Kalinga closed roads across the province; a landslide had also killed a 5-year-old girl and injured two in a home. Two elementary schools in Tanudan were submerged in flooding, though no casualties had been reported there. Another landslide damaged three classrooms and a library, and another had affected 10–15 hectares (25–37 acres) of rice fields. A footbridge had also been damaged by flooding. In Ifugao, four people died in a landslide at Banaue. A 22-year-old man in Aguinaldo drowned after being carried by a strong water current along with one of his companions who survived.[58] A total of 61,547 homes were damaged in Cagayan Valley, mainly in Isabela. The provinces of Cagayan, Isabela, Quirino, and Nueva Vizcaya had all lost power. A river near Roxas and Quirino rose rapidly, flooding low-lying areas.[58] The bridge connecting Roxas and northern Isabela was damaged by the flash flooding.[84] Cauayan Airport was closed for two days after Yutu had blew off the roof of the passenger terminal.[85] In Dinapigue, Isabela, where Yutu made landfall, several barangays were flooded and communication lines were cut off.[86] A landslide in Kayapa blocked the Benguet–Nueva Vizcaya Road, while another occurred in Ambaguio. In Bambang, six low-lying barangays were affected by flooding. In Cagayan, flooding occurred over Gattaran and Tuguegarao.[58] A truck on the Quirino Bridge overturned due to strong winds, causing traffic jams.[87] Fallen trees and debris destroyed graves in Gamu, Isabela.[88]

About 267 homes were damaged in the Ilocos Region, mainly in La Union, and 58 cities or municipalities lost power throughout the region.[58] In Ilocos Sur, Yutu's winds tilted a closed van.[89] Additionally, about 3,000 graves were flooded in Dagupan.[90] In Central Luzon, 675 houses were damaged. In San Clemente, Tarlac, a man died after being electricuted while trying to help another who fell off a motorcycle near a toppled utility pole.[91][92] A rockslide in Baler, Aurora blocked the main highway to Casiguran.[93] In Calabarzon, a fishing boat carrying three fishermen capsized due to big waves near Perez, Quezon; one of them was reported missing before being declared dead by drowning. Polillo and Lucena of Quezon lost power. [58] Strong winds alongside big waves battered Tagkawayan and destroyed nine homes in General Nakar.[89] Two people died from a landslide at a quarry site in Batangas.[94] In Eastern Visayas, 109 homes were destroyed in Northern Samar,[58] including at least 10 in Pambujan that were impacted by waves reaching 3 to 5 m (9.8 to 16.4 ft) and 12 in Mapanas from storm surges. In Gamay, big waves affected several resorts.[95]

Hong Kong

[edit]

On October 31, a 25-year-old man died when surfing in Shek O Beach in Big Wave Bay, Hong Kong Island, due to high surf, while the standby typhoon signal No. 1 was hoisted.[96][61] In Tai Miu Wan, maximum sea level during the storm's passage was measured at 2.78 m (9.1 ft) and a maximum storm surge was measured at 0.65 m (2.1 ft). Over the next two days, Yutu brought cloudy weather and light rain, and overall caused no significant damage in Hong Kong.[61]

Aftermath

[edit]
See also: List of retired Pacific typhoon names

Due to the severe damage in the Northern Mariana Islands and the Philippines, the name Yutu was retired during the 52nd annual session of the ESCAP/WMO Typhoon Committee in February 2020. In February 2021, the Typhoon Committee subsequently chose Yinxing as its replacement name, and was first used in 2024.[97]

In addition, PAGASA officially retired the name Rosita from the rotating lists of tropical cyclone names after the typhoon caused over ₱1 billion in damage on its onslaught in the country, and it will never be used again as a typhoon name within the Philippine Area of Responsibility (PAR), despite this being the first time the name was used in the PAGASA Naming List. It was replaced with Rosal, which was used for the first time in 2022.[98]
