A hovering front and southwesterly airstream yesterday dropped more than 600mm of rain over a few hours in the nation’s northern coastal regions, killing one person and injuring five as of 8pm, authorities said.
The New Taipei City Fire Department said the torrential downpour caused 12 roads in the city to be closed, as well as schools and businesses in Bali (八里), Jinshan (金山), Sanjhih (三芝), Shihmen (石門), Tamsui (淡水) and Wanli (萬里) districts, adding that 256 people were evacuated and 156 were displaced.
New Taipei City Mayor Eric Chu (朱立倫) and New Taipei City Department of Social Affairs Director Chang Chin-li (張錦麗) visited Mackay Memorial Hospital in Tamsui to offer their condolences to the family of the deceased.
Chu said he would authorize district and school administrators to decide when to reopen after assessing the situation.
The delay in closures triggered criticism from the public after the rain worsened, stranding many people.
Rainfall in Shihmen District measured 114mm per hour, nearly the national record of 128mm per hour in Alishan (阿里山), the city government said.
More than 185 areas nationwide reported flooding, while more than 10,000 households were left without electricity, officials said.
The Central Weather Bureau warned that the weather system would bring downpours nationwide, with torrential rain — accumulated rainfall of 350mm or more within 24 hours — or extremely torrential rain — 500mm or more over a 24-hour period — likely on the northern coast.
As of 4pm, accumulated rainfall in several districts of New Taipei City was classified as extremely torrential, reaching 643mm in Sanzhi, 630mm in Shihmen’s Fuguijiao (富貴角), 572.5mm in Jinshan’s Sanhe (三和) and 534mm in Jinshan, bureau data showed.
Elsewhere, accumulated rainfall totaled 428mm in Kaohsiung’s Taoyuan District (桃源) and 356mm in Taipei’s Beitou District (北投), it showed.
President Tsai Ing-wen (蔡英文) and Premier Lin Chuan (林全) said that people in mountainous areas should be evacuated as a precaution to prevent them from being trapped when the weather system passes over southern Taiwan.
The Water Resources Agency said that, in addition to flooded areas in New Taipei City, Keelung’s Jhongshan (中山), Renai (仁愛) and Xinyi (信義) districts were on a level 1 flood alert — imminent flooding if rain continues — and the Jhongjheng (中正), Anle (安樂) and Nuannuan (暖暖) districts were on a level 2 flood alert — possible flooding within three hours if rain continues.
The Directorate-General of Highways (DGH) said that several sections of Provincial Highway No. 2, a major coastal roadway in northern Taiwan, have been closed indefinitely due to flooding and mudslides caused by the rain.
The affected areas are sections 15K-52K between New Taipei City’s Sanjhih and Wanli; 67K-71K along Bisha Port (碧砂港) in Keelung; and 75K-84K between the coastal scenic areas of Ruibin (瑞濱) and Bitou (鼻頭) in New Taipei City, the DGH said.
The DGH urged motorists to avoid using those sections of the coastal highway over the next few days as workers clear debris and perform repairs.
Flights to and from Taipei International Airport (Songshan airport) resumed at 12:43pm after a two-and-a-half hour suspension due to heavy rainfall in Taipei, the Civil Aeronautics Administration (CAA) said.
A total of 137 flights were canceled or delayed at Songshan airport, including three flights that were unable to land and were redirected to airports in Taichung and Kaohsiung, the CAA said.
