BEIJING - China's National Meteorological Center on Sunday renewed its yellow alert for rainstorms in multiple regions of the country, calling for precautionary measures.

From 8 am Sunday to 8 am Monday, downpours are expected in parts of Shaanxi, Sichuan, Chongqing, Henan, Shandong, Jiangsu, Hebei, Beijing and Inner Mongolia, with up to 150 mm of rainfall in certain areas of the southwestern province of Sichuan.
