Core Viewpoint - The southern regions of China are experiencing frequent heavy rainfall since May, with the most intense rainfall expected from May 27 to 29, posing significant disaster risks due to overlapping heavy rain areas [1][3][4] Summary by Sections Rainfall Patterns - Since May, southern China has seen three significant rainfall events, with areas like Guizhou, Guangxi, northern and western Guangdong, northern Jiangxi, southern Hunan, and southern Zhejiang experiencing rainfall amounts 1 to 2 times higher than the same period in previous years [1][3] Upcoming Rainfall Forecast - From May 27 to 29, the southern regions will face the strongest rainfall of the year, characterized by a wide range of rainfall, high intensity, and large daily rainfall amounts. Areas expected to see heavy to torrential rain include eastern and southern Guizhou, western and southern Hunan, southwestern Jiangxi, Fujian, northern Guangxi, and northern Guangdong, with some regions potentially experiencing extreme rainfall and severe convective weather [1][3] Seasonal Weather Influences - This round of heavy rainfall is likely associated with the onset of the South China Sea monsoon, which significantly alters wind patterns and precipitation in the region, marking a critical transition in the climate of East Asia and India. The onset of the South China Sea summer monsoon this year is expected to be slightly later than the average date of May 4 [3] Disaster Risks - The overlapping heavy rainfall areas increase the risk of disasters, particularly in regions such as western and southern Hunan, southern Jiangxi, southern Fujian, northern Guangxi, central and northern Guangdong, eastern and southern Guizhou, and western Yunnan. Potential secondary disasters include mountain floods, geological hazards, small river floods, urban flooding, and agricultural waterlogging [4]
