Since September, the national average precipitation has been 50.2 mm, 17.1% less than the same period in normal years. The autumn rain in West China started on September 15, 13 days later than normal (September 2). From September 11th to 15th, affected by the tropical low pressure and cold air in the South China Sea, heavy precipitation occurred in southern South China. Most of Hainan received 100 to 250 mm of rainfall, with local rainfall ranging from 500 to 800 mm. The rainfall at Wuzhishan Station reached 831.2 mm. On September 14 The station's precipitation reached 615.3 mm on that day, exceeding the historical maximum (354.8 mm on October 13, 1989), and it suffered severe heavy rain and flooding. Some of the above-mentioned areas were accompanied by severe convective weather, including local tornadoes in Wanning and Qionghai, Hainan.

Chao Qingchen, director of the National Climate Center, said that so far, the average rainfall in the southern region of West China during the Autumn Rain is 59.8 millimeters, 20.4% more than the same period in normal years, while the northern region has received 16.9 millimeters, 58.2% less than the same period in normal years.

The eastern part of Northeast China, western Xinjiang, and southern Tibet will also receive more precipitation.
