On October 25, the Central Meteorological Administration reported that the combined effects of Typhoon “Tammei” and a cold front led to wind gusts of 8 to 10 levels in the western and southern parts of Taiwan, as well as along the coasts of Fujian, Zhejiang, and central Guangdong, with some areas experiencing gusts of 11 to 12 levels. Heavy rainfall, including torrential downpours, occurred in the eastern and northern regions of Taiwan, particularly in Taipei, Keelung, and Yilan County.
According to forecasts, Typhoon “Tammei,” currently ranked as the 20th typhoon of the season, is expected to move into the eastern South China Sea, where it could slowly intensify to strong tropical storm or typhoon levels, reaching wind speeds of 28 to 33 m/s (10-12 levels). By the night of October 27, the storm is predicted to gradually turn eastward while its intensity diminishes.
In the next 24 hours, areas such as the western part of the East China Sea, the Taiwan Strait, and northern and central sections of the South China Sea, as well as the Bashi Channel and Dongsha, Zhongsha, and Xisha Islands, are expected to experience winds of 7 to 9 levels and gusts of 10 to 11 levels. Notably, parts of the central and eastern South China Sea may see wind speeds reaching 10 levels, with gusts of 11 to 12 levels.
Throughout today into the night, regions impacted by Typhoon “Tammei” will include southeastern Jiangsu, Shanghai, eastern Zhejiang, northeastern Fujian, eastern Taiwan, and the Xisha and Zhongsha Islands, where moderate to heavy rains are anticipated. Specific areas along the coast of Zhejiang, northeastern Fujian, eastern Taiwan, and the Xisha and Zhongsha Islands may also experience torrential or even extraordinary rainfall.
Looking ahead to October 26, moderate to heavy rains are forecasted for central and southern Jiangsu, southeastern Anhui, most of Shanghai, eastern Zhejiang, southwestern Guangdong, Hainan Island, and much of Taiwan, with areas in central Jiangsu, the eastern coast of Zhejiang, southwestern Guangdong, and Hainan potentially facing heavy rains.
Meteorological experts are urging residents in coastal regions of Jiangsu, Zhejiang, and Shanghai, as well as Hainan Island, to prepare for significant rainfall over the next three days. Additionally, the southern seas are expected to see prolonged strong winds, and vessels along with operational platforms should take precautions against potential storms.
Furthermore, from October 25 to 28, lighter cold air will lead to a temperature drop of 3 to 6°C across parts of central and eastern Northwest China, North China, Inner Mongolia, and Northeast China, with some eastern areas of Northwest China and central Inner Mongolia facing drops of over 8°C. The eastern Tibetan Plateau could see light to moderate snow or sleet, with localized heavy to blizzard conditions anticipated in southeastern Qinghai, northern Sichuan’s plateau region, and parts of eastern Inner Mongolia.
