The Chinese meteorological authority on Sunday issued a heavy rain alert for parts of southern China and a geological disaster warning for areas including parts of Chongqing, where 34 people remain missing more than two days after a landslide.

China’s top flood-control authority said cumulative rainfall could reach 300 to 450 mm in northern and eastern Guangxi from Sunday to Tuesday, equivalent to up to 30 per cent of the entire region’s annual precipitation.
