The Central Meteorological Administration predicts that today will be sunny to cloudy in various places, with scattered brief showers in the south and mountainous areas in the afternoon. The northeast monsoon will strengthen tomorrow, with showers and localized heavy rains in the northeast, and localized short-lived showers in greater Taipei. The northeast monsoon weakened on Saturday but there was still moisture on the windward side. The weather was relatively stable on Sunday, with only localized brief showers on the windward side and in the southern mountainous areas in the afternoon. Another wave of northeast monsoon will strengthen next Monday. This year's No. 26 typhoon "Caiyun" has formed at 2 a.m. today, with a central pressure of 998 hPa. It will move towards Japan and will have no impact on Taiwan's weather.

Wu Derong, an adjunct associate professor at the Department of Atmospheric Science at Central University, pointed out that it will turn to rain in the northern and eastern half of the country from tomorrow to next Sunday, and it will become cooler and the temperature will drop significantly in northern Taiwan next Monday and Tuesday; Light Typhoon Colorful Cloud No. 26 formed over the sea northeast of Guam early this morning and is expected to develop into a large typhoon and head toward the sea southeast of Japan and will not invade Taiwan.

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.

The Central Meteorological Administration predicts that the arrival of the northeast monsoon originally scheduled for October 1 will be postponed by one day, and rain will turn to the north and northeast from Friday. Wang Pinxiang, a forecaster from the Meteorological Administration, said that during the northeast monsoon, the temperature will drop below 30 degrees, about 27 to 28 degrees during the day, and about 24 degrees at night. He also predicted that there will still be some short-lived showers on the north coast of Keelung, the eastern half and the Hengchun Peninsula on Saturday and Sunday.
