TAIPEI (TVBS News) — A developing low-pressure system off Taiwan's eastern coast Wednesday (Oct. 22) has triggered typhoon formation concerns, with meteorologists warning the weather disturbance could intensify if atmospheric conditions persist. Former Weather Chief Cheng Ming-tien (鄭明典) cautioned on Facebook that sustained convection could escalate the system into a full typhoon. The Central Weather Administration (中央氣象局), Taiwan's national weather service, maintains typhoon formation likelihood remains low but confirmed the system's moisture will continue affecting the island.
Heavy rainfall targeting Greater Taipei, Taoyuan, and Yilan counties will persist through the next two days, the Central Weather Administration warned Wednesday. Officials anticipate significant precipitation along Keelung's north coast and throughout Yilan through Thursday (Oct. 23), with potential relief arriving after nightfall. The weather service projects substantial rainfall reduction by Friday (Oct. 25), though complete cessation remains unlikely.
WeatherRisk Explore Inc. (天氣風險公司), a private forecasting company, reported the unexpected low-pressure system has prolonged Taiwan's heavy rainfall period. From Thursday through Friday (Oct. 23-24), precipitation across northern and northeastern regions may ease slightly but could still achieve heavy to torrential intensities. Moisture surrounding Taiwan should decrease significantly by Saturday and Sunday (Oct. 25-26), though mountainous areas in Taipei, New Taipei, and Yilan may continue experiencing substantial rainfall. ◼
