China's State Flood Control and Drought Relief Headquarters on Monday initiated a Level-IV emergency response in Guangdong, Hunan and Jiangxi and maintained the same level emergency response in Fujian, Guangxi, Zhejiang and Guizhou in anticipation of potential flooding, as intense rainstorms continued to batter the south and the east of the country.

As of Monday, rainstorms, mountain torrents and landslides had killed four people in Shanghang County and four people in Wuping County, both located in east China's Fujian Province, and five people in the city of Meizhou in south China's Guangdong Province, according to local authorities.

Outdoor activities should be avoided during such high temperatures, and precautionary measures should be taken to protect vulnerable groups such as children and older people, the center said.

China's Ministry of Agriculture and Rural Affairs activated a Level-III emergency response to drought in Hebei, Shanxi, Shandong and Henan on Monday as sweltering heat continued to bake parts of the country.
