Heat Warning for Changhua, Hualien, and Taitung: Wu Derong Predicts Over 38°C During Dragon Boat Festival Holiday

Central News Agency Report

(CNA reporter Chang Hsiung-feng, Taipei, June 18) — The Central Weather Administration issued high-temperature alerts today for Changhua County and the Hualien-Taitung region, warning of temperatures exceeding 36°C. Meteorological expert Wu Derong stated that from tomorrow (Dragon Boat Festival) through June 24, the Pacific high-pressure system will intensify, bringing clear, hot weather akin to midsummer across Taiwan, with maximum temperatures reaching over 38°C.

The Central Weather Administration released a high-temperature advisory this morning. Due to the subsidence effect of the southwest wind, the weather is hot and dry, with a risk of foehn winds in Taitung County. Today, Changhua County, Hualien County, and Taitung County are under a yellow alert, indicating the need to prepare for temperatures above 36°C.

Wu Derong, adjunct associate professor in the Department of Atmospheric Sciences at National Central University, wrote in the 'Leak the Heavens Classroom' column of the Meteorological Application and Promotion Foundation that the latest European model simulations show weakening southwest monsoon today, leading to partly cloudy to sunny conditions across Taiwan with hot daytime temperatures, with maximums reaching 36°C. Although atmospheric conditions are more stable than yesterday, isolated afternoon showers or thunderstorms are still possible.

Wu noted that from tomorrow through June 24, the Pacific high-pressure system will strengthen, causing temperatures to rise day by day. Clear and scorching weather resembling midsummer is expected across Taiwan, with maximum temperatures exceeding 38°C. Mountainous areas may experience brief, localized afternoon showers.

He added that from June 25 to 27, the final meiyu front of the rainy season will approach. The extent of its southward movement and the trajectory of tropical disturbances remain uncertain, as global models show divergent results, indicating high variability. Continuous monitoring is advised.

Wu mentioned that a tropical disturbance may develop east of the Philippines around June 20–21. While global models differ in predicting its path, most suggest it will recurve northeastward over the sea south of Japan, posing a low threat to Taiwan. However, due to uncertainty, ongoing observation is necessary. (Edited by Li Shu-hua) 1150618
