Part of the 2017 Pacific typhoon season

Tropical Storm Kai-tak, known in the Philippines as Tropical Storm Urduja, was a late-season tropical cyclone that affected Visayas during December 2017. Forming as the twenty-sixth named storm of the 2017 Pacific typhoon season, Kai-tak formed as a tropical depression near Palau on December 11. Slowly intensifying, the system became a tropical storm on December 14. Due to its slow motion, Kai-tak made landfall in Samar on December 16, and traversed the Philippine islands. Kai-tak later moved in a west-southwestward direction until it dissipated on December 23 near Malaysia.

The storm created a total of 83 fatalities, and 74.3 million US dollars[a] in damage. Massive floods and landslides were created, leading to massive rescue operations and aid operations made by the local government. The effect of the storm led to the retirement of the name Kai-tak, and later Urduja.

On December 10, the Joint Typhoon Warning Center (JTWC) began to monitor a tropical depression located about 130 km (80 mi) to the east of Palau.[1] The Japan Meteorological Agency (JMA) classified the system as a weak tropical depression the next day,[2] and began issuing advisories on 00:00 UTC of December 12.[3] Nine hours later, the PAGASA declared that the system had intensified into a tropical depression and was immediately given the local name Urduja.[4] On December 13, the JTWC issued a Tropical Cyclone Formation Alert.[5] On 21:00 UTC of that same day, the JTWC upgraded the system to a tropical depression and also began issuing advisories, giving the identifier 32W.[6] Despite the system being poorly organized with loose banding, the system also was located in an area of very low wind shear.[7] Three hours later, the JMA upgraded the system to a tropical storm, assigning it the international name Kai-tak.[8][9] The next day, the storm started moving towards Eastern Samar, then moved towards the other direction. The next day, the storm made landfall towards the Samar Island. After, the storm made landfall in the Visayas archipelago, leaving the Philippines. Over the following days, the storm made landfall over the South China Sea before dying out on December 23.[10] On December 20, during the storm, analysis showed that the strongest part of the storm was hovering over the South China Sea, with another part hovering over Palawan because of a general flow of the South China Sea.[11] Parts of the storm also were classified as "very cold" and supposedly also brang rainfall.[12] On December 18, NASA said that the storm was about 20 knots and had a rainfall rate of 7.59 inches per hour..[13]

Preparations and impact

[edit]

Philippines

[edit]

On December 12, cloudy skies and thunderstorms were predicted in the Mindanao region of the Philippines, with other closer regions having a possibility of flash floods and landslides.[4] On December 14, as soon as PAGASA upgraded Kai-tak (Urduja) to a tropical storm, Public Storm Warning Signal #2 was immediately raised in Eastern Samar, Samar and Biliran.[14] Public Storm Warning Signal #1 was also raised in the majority of Bicol Region (Region V) and much of Visayas while moderate to heavy rainfall were warned within a 400 km2 (150 sq mi) of the storm.[14][15] Residents were already advised to "undertake appropriate measures" against flooding as the moderate to heavy rainfall area was extended to within a 500 km2 (190 sq mi). On December 15, PAGASA also announced the possibility of a storm surge of 4.1–14 metres (4.5–15.3 yd) over in Samar.[16]

The city of Tacloban was later placed under a state of calamity as decided by their local council as 80 of the 130 villages were flooded. This resulted in at least 728 families (1,418 individuals) brought to evacuation centers or schools.[17] On December 14 at approximately 06:00 UTC,[b] the storm made landfall over the province of Eastern Samar. Heavy rainfall was also predicted from a 400 km (250 mi).[14] Sea travel near the affected areas were later cancelled because of the storm.[16] The storm later flooded some parts of the Philippines and caused some landslides, with 23 people dying in the sole province of Biliran,[18] which included a landslide killing 27 people in the Naval barangay of Lucso-on.[19] Two people also died in Mimaropa, and 78 people were injured from the storm.[20] The NDRRMC noted at least 89,000 people fleeing to evacuation centers.[21] Three people also died in the province of Leyte, with a boy who drowned in the town of Mahaplag, a woman buried by a landslide, and another person who drowned in Ormoc. Vice-Governor of Eastern Samar Marcelo Picardal also stated that half the towns in Eastern Samar was flooded.[22] The NDRRMC confirmed a total of 83 people dead and calculated a total of Php3.747 billion (US$74.3 million) worth of infrastructure and agricultural damages,[23][24] affecting 44,500 farmers.[25] Damage for the provinces of Eastern Samar, Masbate, and other closely affected areas amounted over Php543,000 (US9.5 thousand) and agricultural damage near the affected areas totaled over Php400 million (US6.9 million).[26] The flood also contaminated Tacloban City's supply of tap water.[22] In a case study, an estimated amount of 35,286 homes were damaged, with 2,748 of them being totally destroyed and 32,538 being partially damaged, and the study also showed that 1,800,000 individuals were affected by the storm.[27] There were also affected families in Mimaropa, the Western Visayas, and Caraga,[28] and 11,000 people were stranded in ports around the country.[29] Power lines in 39 settlements toppled and some bridges fell to the ground.[30] After, other southern provinces were affected, including Cagayan de Oro, Lanao del Sur and Norte, and some parts of the Zamboanga Peninsula.[31]

Retirement and aftermath

The retrieval operations are still ongoing but we are not finding anyone alive. We only find dead bodies.

— Sofronio Dacillo

After the storm, retrieval operations started, with over 40 people missing, mostly declared dead. In Biliran, bulldozers dug dirt in hopes of finding bodies.[32][33] Military trucks also drove in flooded areas, trying to rescue trapped residents.[22] After the storm hit, president Rodrigo Duterte paid a visit to the storm-affected areas.[21] Affected people were brought to shelters, where tap water was donated by local charities. Some local government units initiated their response and distributed shelter materials and aid. The local MSWD offered 40 people to help aid projects and other needs.[27] A local Mormon church in Tanauan, Leyte donated supplies to students from Sacme, a local farming village.[34] Php184 million worth of aid was also given to affected residents, coming from the Department of Social Welfare and Development, local government units, and other charities.[35]

On December 21, 2017, the PAGASA announced that the name Urduja had been retired from their naming lists after causing more than ₱1 billion worth of damage, also never using it again as a typhoon name within the Philippine Area of Responsibility (PAR).[26]

Due to the damage and high death toll in Visayas, the name Kai-tak was officially retired during the 50th annual session of the ESCAP/WMO Typhoon Committee in February 2018. In February 2019, the Typhoon Committee[c] replaced it with the name Yun-yeung, which was first used at the 2023 season.[36]

Just a few days after the storm, another storm called Typhoon Tembin[d] hit the Philippines, leading to 266 deaths.[37]
