[Heavy rainfall to peak in south China tomorrow, accompanied by severe convective weather] South China will experience a new round of heavy rainfall from today (May 21) to May 24, with tomorrow being the peak period of this rainfall event. Heavy rain and torrential rain are expected in parts of Anhui, Hubei, Hunan, Jiangxi, and Guangxi, with extremely heavy rain in some localized areas, accompanied by severe convective weather. In some regions, the rainfall will exceed 60 millimeters in six hours, and even surpass 120 millimeters in localized areas. The areas affected by this round of heavy rainfall overlap significantly with regions that have already experienced above-average precipitation, and the public is advised to guard against secondary disasters such as geological disasters and mountain floods. Recently, rainfall has been frequent in south China, generally characterized by "weak overall intensity but strong in localized areas," with a wide rainfall coverage but relatively low overall intensity, and intense rainfall in some regions. For example, yesterday, rainfall occurred in multiple regions including Guizhou, Hunan, Guangxi, Guangdong, Jiangxi, Hunan (repeated), and Zhejiang, with heavy rain and torrential rain observed in parts of northern Jiangxi, northwestern Guizhou, and southern Anhui.
