Taipei: The unstable weather that has recently affected Taiwan is anticipated to continue, driven by southwesterly winds and the outer bands of Tropical Storm Co-May. The Central Weather Administration (CWA) has forecast significant rainfall in central and southern Taiwan, with the possibility of short-duration heavy downpours or localized torrential rain.

According to Focus Taiwan, the CWA has issued advisories for torrential or extremely heavy rain in Tainan, Kaohsiung, and Chiayi cities, as well as Pingtung, Chiayi, and Taitung counties in southern Taiwan, and the outlying Penghu County. The CWA defines torrential rain as more than 350 mm in 24 hours or 200 mm in three hours, while extremely heavy rain is characterized by over 200 mm in 24 hours or 100 mm in three hours. A heavy rain warning is also in place for Keelung, Taipei, New Taipei, Taoyuan, Hsinchu, Changhua, Nantou, and Yunlin, where rainfall could exceed 80 mm in 24 hours or 40 mm in an hour.

The advisories are expected to remain in effect until Tuesday night. Temperature forecasts indicate highs of 30-33 degrees Celsius nationwide during the day, with lows between 25 and 27 degrees.

Independent meteorologist Wu Der-rong noted that the unstable weather is likely to persist until August 4, with scattered showers or thunderstorms possible. The latest European forecast model suggests that a Pacific high-pressure system will strengthen on August 6 as southwesterly winds diminish, leading to a return of hot and sunny weather in Taiwan. Tropical Storm Co-May, located approximately 430 kilometers northeast of Taipei and moving at 22 km per hour in a west-northwest direction, is projected to head towards Zhejiang and is not expected to directly impact Taiwan.
