The northeast monsoon continues to influence Taiwan, bringing increased moisture and localized showers to northern regions, the eastern part of the island, and the Hengchun Peninsula. While northern temperatures have seen a slight cooling, central and southern regions remain hot, with daily temperature fluctuations reaching approximately 10°C.

Weather conditions are expected to improve by Thursday and Friday as the monsoon weakens and moisture levels decrease. This shift is projected to lead to mostly cloudy to sunny skies and a slight rise in temperatures across the north and east. By the weekend, conditions are expected to become drier, with rain potentially limited to the northern coast of Keelung, the northeast, and some mountainous areas.

Regarding tropical systems, tropical depression TD28, located east-northeast of Guam, is expected to strengthen into Typhoon Krathon, the 21st typhoon of the year. While earlier projections suggested the system might develop into Typhoon ‘Dujuan’ and move toward the Ryukyu Islands and Japan between September 21 and 23, the system is now identified as Krathon. Although a direct impact on Taiwan is currently considered unlikely, its exact path remains uncertain. If the typhoon turns north near Okinawa, its outer circulation could bring cooler northern winds to Taiwan; otherwise, warm easterly winds may maintain high temperatures.
