Wu Derong: Hot and Sunny Week from Dragon Boat Festival; Tropical System Expected to Develop by Weekend

(Central News Agency reporter Chang Hsiung-feng, Taipei, June 16) Meteorologist Wu Derong said that it will feel warm during non-rainy periods over the next two days, with hot and sunny summer-like weather expected across Taiwan from the Dragon Boat Festival (June 19) through June 25. A tropical disturbance may develop east of the Philippines around June 20–21, and while it is not expected to affect Taiwan, there remains some uncertainty, requiring continued observation.

The Central Weather Administration issued a land-based strong wind advisory today, warning of strong southwest winds. From this morning through tomorrow night, localized areas in Taoyuan City, Hsinchu City, Hsinchu County, Miaoli County, Taichung City, Taitung County (including Green Island), Penghu County, and Lienchiang County should prepare for sustained winds of Beaufort scale 6 or higher, or gusts reaching Beaufort scale 8.

Wu Derong, adjunct associate professor in the Department of Atmospheric Sciences at National Central University, stated in the 'Leak the Heavens Classroom' column of the Foundation for the Promotion of Meteorological Applications that the latest European model simulations show the lingering front slightly weakening over the next two days but still within the southwest monsoon range, making daytime periods feel slightly warm when not raining. Windward areas are prone to rainfall, and afternoon convection will remain active.

Wu noted that the southwest monsoon will weaken on the 18th, with localized thunderstorms still possible in the afternoons. From June 19 to 25, the Pacific high-pressure system will strengthen, bringing hot and sunny summer-like conditions across Taiwan, with occasional brief afternoon showers in mountainous areas.

Wu mentioned that a tropical disturbance may develop east of the Philippines around June 20–21. While international model simulations vary in their projections, most suggest the system will take a large northeastward turn over waters south of Japan, posing no threat to Taiwan. However, due to remaining uncertainty, continued monitoring is necessary. (Edited by Chang Ya-ching) 1150616
