Jia Xingxing, director of Taiwan Integrated Disaster Prevention Engineering Technology Consulting Company, said that starting from tomorrow, there will be a two-stage cooling, especially in the second wave of low temperatures in the open areas in the north, which will drop to around 18 degrees. The northeast monsoon has been reported, and there will be rainfall on the north coast, northeastern corner, and Yilan. Typhoon Caiyun has formed in the early hours of this morning, and a cross-border hurricane NOLO will also move into the central Pacific.

Typhoon No. 26 "Caiyun" was generated on the 1st. It is expected to develop into a strong and wide-circulation system. However, it will not directly affect Taiwan as it moves northward. Instead, it will indirectly promote the northeast monsoon that will last for a long time near Taiwan next week. The northern and eastern half will be significantly cooler. Rainfall will be concentrated on the north coast, the northeastern corner, Yilan and other places. The daytime high temperature in Taipei after next Monday is expected to remain at 25-30 degrees, and the nighttime low temperature will be 20-25 degrees.

On the first day of the National Day holiday, the cold air continues to move eastward and southward, and many places in the south will join the cooling process. From October 3rd to 4th, a new wave of cold air will move southward, and temperatures in many places in the north and south will hit record lows in the second half of this year. The rainfall in the south is relatively large, and some areas in the southwest need to be prepared for secondary disasters.

Tropical depression TD30 is located in the northeast and east of Guam. It is expected to intensify into Typhoon "Caiyun", the No. 27 internationally numbered typhoon, which can reach the intensity of a severe typhoon and move northward. However, it is not expected to directly affect Taiwan, and the probability of affecting the Japanese mainland is not high. Whether the external circulation will affect Kantō and Tohoku of Japan still needs to be observed in the later path.

Meteorological expert "Taiwan Typhoon Forum | Weather Emergency" stated that the intensity of Typhoon No. 25 Shuliji has been significantly weakened. The Central Meteorological Administration confirmed that it weakened into a mild typhoon at 8:00 on the 29th. It is located 1,290 kilometers northeast of Taipei. In the coming week, tropical systems near Guam and the northwest Pacific Ocean will be active. It is expected that 1 to 2 typhoons will form, but there is no sign of approaching Taiwan.

Today and tomorrow, the Greater Taipei Basin, the western inland and the East Longitudinal Valley will have a high temperature of about 36 degrees, and it will feel hot around noon. The northeast monsoon will strengthen from Thursday, with increasing cloud cover and the chance of brief showers in the north and east. The high temperature will drop to 28 to 31 degrees, and the heat will ease. The impact will be less in the central and southern parts, where the high temperature will still remain at 32 to 35 degrees.
