Weather Forecast: New Typhoon Coming? Taiwan Faces Weather Shift! 'Heavy Rain for 3 Consecutive Days' Starting This Day — When Will It Clear Up?

The Central Weather Administration issued a high-temperature advisory today (16th), urging caution against temperatures exceeding 36°C in six counties and cities: Taipei, New Taipei, Taoyuan, Changhua, Yunlin, and Hsinchu. Meteorological expert Wu Derong pointed out that Taiwan will be affected by a low-pressure belt this week, leading to continued atmospheric instability. Rainfall is expected to become more pronounced from Friday to Sunday (August 21–23). Additionally, a tropical disturbance is likely to form over the sea east of Guam starting Thursday (August 20), and its subsequent movement warrants close attention.

High-Temperature Alert for 6 Counties and Cities! Low-Pressure Belt to Intensify Rainfall This Week—Wu Derong Reveals Timing of 'Tropical Disturbance' Formation

Due to the scorching heat, the Central Weather Administration has issued high-temperature warnings for six counties and cities today, urging the public to guard against heatstroke.

High-Temperature Warning Levels and Affected Areas:

- Orange Warning: Taipei City, New Taipei City, Taoyuan City, Changhua County, Yunlin County - High probability of consecutive days with temperatures reaching 36°C or higher - Yellow Warning: Hsinchu County - Caution advised for temperatures exceeding 36°C

Wu Derong, adjunct associate professor at the Department of Atmospheric Sciences, Chung Yuan Christian University, stated in the 'Leak the Heavens Classroom' column of the Meteorological Application and Promotion Foundation that daytime temperatures will remain high across regions before rainfall occurs. He urged the public to take sun protection measures and stay hydrated when going outdoors.

Weather Outlook for the Next Week: Rain Trends and Preparedness for Severe Weather

In the 'Leak the Heavens Classroom' column, Wu Derong explained that the latest European model simulations indicate Taiwan's weather this week will be influenced by a low-pressure belt, with abundant moisture. The weather changes at each stage are as follows:

· Sunday to Thursday (August 16–20): Frequent strong convection in the afternoons

From today through Thursday (August 20), the monsoon circulation has weakened and shifted westward. Taiwan is situated within a low-pressure environment, and the atmosphere remains unstable. Scattered localized rains are expected, with strong convection frequently developing in the afternoons.

· Friday to Sunday (August 21–23): More significant rainfall; prepare for severe weather

From Friday to Sunday (August 21–23), the low-pressure belt will move northward and pass over Taiwan, resulting in more pronounced rainfall. Strong convection may bring severe weather such as lightning, strong winds, and sudden heavy downpours. The public should pay attention to short-term weather updates and special advisories.

· Monday to Tuesday (August 24–25): Weather clears up, turning hot again

Wu Derong stated that the latest model simulations show the Pacific high-pressure system will slightly strengthen from Monday to Tuesday (August 24–25), leading to clear and hot weather across Taiwan. Sun protection and heatstroke prevention remain essential. However, there is still a chance of localized afternoon rains in mountainous areas.

Will a new typhoon form? Tropical disturbance east of Guam expected to develop from August 20—path forecast revealed

Regarding the potential development of typhoons or tropical systems recently, Wu Derong noted the following based on the latest model simulations:

· Development Timing: Starting Thursday (August 20), a tropical disturbance is expected to form over the sea east of Guam.

· Predicted Path: The tropical disturbance will move northwestward, reaching the sea south of Japan around next Tuesday (August 25).

· Impact on Taiwan: Currently, it is assessed that the system may not approach Taiwan closely. However, as this is a late-stage simulation, its future movement still requires continuous monitoring.
