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.

During the National Day holiday, most areas across the country have good weather conditions and are suitable for travel. It will be mainly sunny to cloudy in the north, and there will be precipitation in North and Northeast China; it will rain first and then become clear in the south, and the rain will be stronger in the southwest.

The two waves of cold air relay influence, the coolness in the north becomes more intense, and the heat in the south subsides. In the second half of the Yangtze River, the temperature drops to about 15℃ in the morning and evening.

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.
