Heavy Rain Alert for Southern Changhua and Beyond; Wu Derong: Summer Heat Returns Nationwide from 19th

(Central News Agency reporter Chang Hsiung-feng, Taipei, June 15) The Central Weather Administration today issued alerts for torrential rain in Penghu and heavy rain in areas south of Changhua and in Nantou. Meteorological expert Wu Derong stated that central and southern Taiwan should remain vigilant for severe weather over the next two days. From June 19, weather across Taiwan will turn sunny and hot, resembling peak summer conditions. A tropical disturbance developing east of the Philippines shows signs of activity, but it will not approach or affect Taiwan.

The Central Weather Administration issued a torrential rain advisory this morning. Affected by southwest winds, short-duration heavy rainfall is likely. Today, Penghu County may experience localized heavy or torrential rain, while areas south of Changhua and Nantou face risks of localized downpours. The public should remain alert for lightning and strong gusts. Mountainous regions should watch for landslides and falling rocks, and low-lying areas should prepare for potential flooding.

Wu Derong, adjunct associate professor in the Department of Atmospheric Sciences at Central University, wrote in today’s column “Leak the Heavens’ Secrets Classroom” on the Meteorological Application and Promotion Foundation’s website. According to the latest European model simulations, the stationary front will shift slightly southward over the next two days, bringing unstable southwest monsoon winds. Central and southern Taiwan, on the windward side, face threats of severe weather including lightning, strong winds, and sudden intense rainfall. Other regions may also experience heavier-than-usual rain.

Wu noted that model simulations indicate the stationary front will move northward again on the 17th and 18th. Daytime temperatures will be relatively high when not raining. On the 17th, the region remains under the influence of the southwest monsoon, with rainfall likely on the windward side and strong afternoon convection. On the 18th, the southwest monsoon weakens, and convective intensity is expected to decrease.

Wu stated that from June 19 to 24, the Pacific high-pressure system will strengthen, bringing clear and hot summer-like weather across Taiwan. Mountainous areas may experience occasional localized brief afternoon showers.

Wu mentioned that a tropical disturbance east of the Philippines shows signs of development from June 19 onward. While international model simulations vary in their projections, most suggest the system will move northeastward over the sea south of Japan, making a turn away from Taiwan. There is no risk of direct impact, but due to uncertainty, continued monitoring is advised. (Edited by Chang Ya-ching) 1150615
