China's National Climate Center announced the arrival of the South China Sea summer monsoon on Thursday, marking the gradual start of the country's main flood season.

This year's monsoon, characterized by increased convective activity and potential for higher precipitation across East Asia, commenced on May 26. Compared to typical years, this is roughly a 10-day delay and exhibits lower initial intensity.

The National Meteorological Center forecasts that within the next two weeks, the monsoon's flow will transport warm, moist air from the Indian Ocean and South China Sea northward towards East Asia. This could lead to enhanced heavy rainfall events in regions south of the Yangtze River.

Accumulated precipitation across southwest, east, and South China is expected to range from 40 to 80 millimeters over the next ten days. Localized areas in southern Guizhou, southwestern Guangdong, and southeastern Xizang could receive rainfall exceeding 250 millimeters.

While South China has already experienced several late-May precipitation events, with provinces like Fujian, Guangdong, and Hainan seeing above-average rainfall, the monsoon's arrival signifies the rainy season's progression rather than its peak intensity. Most parts of China are anticipated to experience higher-than-normal rainfall throughout June.
