Beijing: China's meteorological authority on Saturday issued a blue alert, the lowest in a four-tier warning system, for rainstorms in the country's southern region.

From Saturday to Sunday, storms bringing 50 to 120 millimetres of rain will pelt parts of Hubei, Guizhou, Anhui, Hunan and Jiangxi provinces, the National Meteorological Center (NMC) said in a statement.
