China's meteorological authority has warned of more possible geological disasters in the south of the country, as heavy rain continues to pound many regions.

The National Meteorological Center on Saturday said there was a high risk of geological disasters in parts of Fujian, Jiangxi Provinces and the Guangxi Zhuang Autonomous Region. It suggested people in the areas take precautions against possible mountain torrents, mud-rock flows and landslides.

The warning comes as authorities renewed a blue alert for rainstorms on Saturday afternoon, forecasting that heavy rain will continue in Guizhou, Hunan, Guangxi, Jiangxi, Fujian and Zhejiang until Sunday night. Precipitation in some places is expected to reach up to 120 millimeters.

China has a four-tier color-coded warning system for severe weather, with red being the most serious, followed by orange, yellow and blue.
