South Faces Persistent Heavy Rain and Afternoon Storms
Southwest winds continue to pump moisture across the southern half of the island, creating widespread atmospheric instability. According to reporting from the United Daily News (UDN), heavy rain advisories remain in place for Tainan, Kaohsiung, and Pingtung, with immediate heavy rain alerts issued for Kaohsiung, Pingtung, and Taitung.
Daytime temperatures across the island range widely, with northern areas reaching 24 to 36 degrees Celsius, central regions hitting 23 to 35 degrees Celsius, southern areas seeing 24 to 34 degrees Celsius, and eastern areas reaching 23 to 36 degrees Celsius.
Typhoon Fujiwara Effect and Active Monsoon Trough
Beyond the immediate southern downpours, meteorological monitoring tracks two distant storms currently active in the Pacific. According to NOWnews and UDN reporting, the 21st typhoon of the season, Atao, is moving north-northwest past Wake Island, while the 22nd typhoon, Ban Lang, follows closely behind.
Both systems are experiencing a Fujiwara effect, interacting and orbiting around one another over the open ocean. However, because both systems remain thousands of kilometers away from the island, experts confirm they pose no direct threat to Taiwan.
Looking ahead to the following week, forecasters point to an active monsoon trough developing across the region. Tropical disturbances are showing signs of formation both in the seas east of Taiwan and in the South China Sea, creating a complex environment where systems mutually interfere and constrain one another’s paths.
According to Wu’s analysis cited by UDN and NOWnews, computer forecasts from both global physical models and AI-based systems show high variability and uncertainty regarding potential typhoon formation or exact tracks. Because Taiwan sits directly in the transition zone between the monsoon trough and a broader low-pressure system, daily rainfall intensity and timing will depend heavily on how these tropical disturbances evolve in the coming days.
