Greater Taipei on Alert for Heavy Rain on May 5; Stationary Front to Bring Rain Across Taiwan Next Week
The Central Weather Administration (CWA) issued heavy rain advisories on June 4. A tropical system will bring rain to all of Taiwan on May 5, with a risk of heavy downpours in Greater Taipei and central-northern mountainous areas. Next week, a stationary front and southwesterly winds are expected to bring continuous rain across Taiwan from June 9 to 14. The system may develop into Typhoon Meari but is forecast to move towards Japan.

(Central News Agency, reporter Zhang Xiongfeng, Taipei, June 4) The Central Weather Administration (CWA) issued heavy rain and torrential rain advisories for multiple areas this afternoon. Tomorrow, a tropical system will affect Taiwan, bringing rain across the island, with heavy rain expected in the mountainous areas of central and northern Taiwan and the Greater Taipei area. Next week, due to a stationary front and southwesterly winds, rain is expected to fall continuously for a week, and the CWA has not ruled out activating large-scale heavy rain operations.
CWA forecaster Lai Xin-guo told CNA that a tropical system in the Bashi Strait is approaching Taiwan and is predicted to pass through as a low-pressure area or tropical depression. When it enters the waters east of Taiwan, due to favorable environmental conditions, it could potentially strengthen into this year's 7th typhoon, Meari.
Lai stated that according to current model predictions from various countries, if Meari forms, it will move towards Japan and will not directly affect Taiwan.
However, tomorrow, due to the influence of the low-pressure area or tropical depression, weather across Taiwan will be unstable, with a high likelihood of localized heavy rain. The CWA specifically warned of strong afternoon convection, which could lead to short-duration, intense heavy rain in the mountainous areas of central and northern Taiwan and the Greater Taipei area.
Lai said that on June 6, the low-pressure area or tropical depression will gradually move away, and rainfall across the island will ease, though there may be localized heavier rain in the mountainous areas of western Taiwan. On June 7, with southwesterly winds, central and southern Taiwan may experience localized brief showers or thunderstorms, while northern and eastern Taiwan may have afternoon thunderstorms, with a particular risk of short-duration heavy rain or torrential rain in the eastern regions.
Starting June 8, a front from the north will approach, combined with southwesterly winds, making western Taiwan and Yilan prone to brief showers or thunderstorms, with localized heavy rain in mountainous areas in the afternoon. Other areas will see brief afternoon thunderstorms. From June 9, the front will become stationary, and with continued southwesterly winds, rainy weather is expected across Taiwan until June 14. Western Taiwan and northeastern Taiwan will experience showers or thunderstorms, with localized heavy or torrential rain. The CWA has not ruled out activating "large-scale or severe heavy rain operations."
Regarding temperatures, Lai mentioned that the highest temperature today was 39.4 degrees Celsius in Yuli Township, Hualien County. Areas exceeding 36 degrees were concentrated in the Huatung Valley, mainly due to strong daytime solar radiation and the local topography, which tends to accumulate heat and cool slowly, leading to localized high temperatures around noon. Tomorrow, due to rainfall across the island, high temperatures will drop to around 30 to 32 degrees Celsius, but it will still be somewhat muggy before the rain starts.
Lai also reminded that there is a risk of long-period swells along the southwestern coast and the Hengchun Peninsula tomorrow. (Editor: Chen Qingfang) June 4, 2025
