China's meteorological authority continued a yellow alert for rainstorms on Wednesday.
Rainstorms or heavy rains are expected to hit parts of Guangdong, Guangxi, Hunan, Jiangxi, Fujian, Zhejiang, Yunnan, Taiwan and Jilin, said the National Meteorological Center.
Some southern regions will experience torrential rains, with precipitation up to 240 mm in parts of Guangdong, Hunan, Jiangxi and Fujian.
The center advised local governments to keep alert to possible flooding, landslides and mudslides caused by heavy rain and recommended outdoor operations be halted in hazardous areas.
China has a four-tier color-coded weather warning system, with red representing the most severe, followed by orange, yellow and blue.
