China's national observatory has issued a blue alert for heavy rain in some southeastern and western regions.
Until Saturday morning, heavy rain is expected to hit parts of Jiangxi, Fujian, Guangdong, Gansu, Shaanxi, Sichuan, Guizhou provinces and Chongqing as well as China's Tibet and Taiwan, the National Meteorological Center said Friday.
Some areas in Guangdong and Taiwan will be hit by up to 140 mm of rainfall within 24 hours.
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.
