Wu Der-rong: First Plum Rain Front Arrives, Central and Northern Taiwan Turn Rainy and Cooler
Weather expert Wu Der-rong announced that the first plum rain front will affect Taiwan today and tomorrow, bringing localized showers or thunderstorms and cooler temperatures to central and northern regions. The weather will stabilize over the weekend, but another front will arrive from the evening of the 8th to the 9th, bringing wet and cool conditions again to central and northern Taiwan.

Weather expert Wu Der-rong said today that the first plum rain front will affect Taiwan today and tomorrow, bringing localized showers or thunderstorms to central and northern regions and a drop in temperature; the weather will stabilize on the 6th and 7th, but another front will arrive from the evening of the 8th to the 9th, bringing wet and cool conditions again to central and northern Taiwan.
Wu Der-rong, an adjunct associate professor in the Department of Atmospheric Sciences at National Central University, stated today in the 'Leak the Heavenly Secrets Classroom' column of the Weather Application Promotion Foundation that observational data show frontal cloud systems are currently over South China to near Taiwan, with localized rainfall already occurring in northern Taiwan and Yilan/Hualien.
Wu Der-rong said that the latest European model simulations indicate that central and northern Taiwan will experience localized showers or thunderstorms today and tomorrow due to the first 'plum rain season (May, June)' front. Southern regions will also see localized brief showers or thunderstorms tomorrow, and attention should be paid to lightning, strong winds, and instantaneous heavy rainfall. Temperatures will gradually drop across all areas today, with northern Taiwan turning cooler.
Wu Der-rong stated that from the morning of the 6th to the 7th, the front will weaken and move away, and the weather will improve across all areas, with temperatures gradually rising. Occasional localized brief rainfall may occur in mountainous areas and eastern Taiwan in the afternoon; all areas will be clear to partly cloudy and summer-like hot during the daytime on the 8th. From the evening of the 8th to the 9th, the second plum rain front will affect Taiwan, bringing localized showers or thunderstorms to central and northern Taiwan and southern mountainous areas, with temperatures dropping.
Wu Der-rong pointed out that the latest European model simulations show that from the 10th to the 13th, the front will weaken and move away, and the weather will improve across all areas, with temperatures rising again. However, the simulations from various countries for the later period are inconsistent and will continue to be adjusted, requiring ongoing observation. (Editor: Li Heng-shan)1150504
