The formation of Typhoon No. 26 "Caiyun" will move the ocean northward without affecting Taiwan, indirectly promoting the continuation of the northeast monsoon

Typhoon No. 26 "Caiyun" is generated and is expected to develop into a strong typhoon, and it will be a system with a large circulation range. Fortunately, it will move northward in the ocean and will not directly affect Taiwan. Instead, it will indirectly promote the northeast monsoon that will last for a long time near Taiwan next week.

Wu Shengyu, a senior consultant at the Weather Risk Company, said on Facebook that the northeast monsoon will arrive tonight (1st). After nightfall, rainfall will begin in the windward north coast, northeast corner, and Yilan. Tomorrow and the day after tomorrow (2-3), rainfall will increase in Taoyuan, Greater Taipei, Keelung's north coast, Yilan, and northern Hualien. Among them, the north coast of Keelung, the northeast corner, and Yilan will experience more accumulated rainfall. The impact in the Taitung area south of Hsinchu is not obvious, and it will generally remain cloudy to sunny, with only some localized short-lived shower opportunities in the mountainous areas in the afternoon.

On Sunday (4th), the northeast monsoon will bring less rainfall. Next Monday (5th) will be another wave of strong northeast monsoon heading south. Rainfall in the windward areas will become more obvious again, and there is a chance of locally larger cumulative rainfall. It is expected that the northeast monsoon next week will be strong and last for a long time, and the northern and eastern half will become significantly cooler.

Taipei's temperature forecast shows that after next Monday (5th), the daytime high temperature will fall between 25 and 30 degrees for a long time, and the night and early morning low temperatures will also fall between 20 and 25 degrees. Taichung and the south will be less affected. The daytime high temperature will still be above 30 degrees, and the night and early morning will be cooler. Especially in areas where radiation cooling occurs, the temperature difference between day and night is more obvious.

Caiyun has the chance to become a large and powerful typhoon. Fortunately, it seems that it will move northward over the open sea and will not approach Taiwan. The circulation will not affect Taiwan. Instead, it will indirectly promote the northeast monsoon that will last for a long time near Taiwan next week.
