China's meteorological authority on Sunday issued a yellow alert for high temperatures, urging people to reduce outdoor activity.
On Monday, temperatures will exceed 35 degrees Celsius in Anhui, Chongqing, Gansu, Henan, Jiangsu, Shaanxi, Xinjiang and Zhejiang, the National Meteorological Center announced.
Some of those regions will experience temperatures up to 40 degrees, the center said.
China has a four-tier color-coded weather warning system, with red representing the most severe warning, followed by orange, yellow and blue.
The center warned that people -- especially the old, young and infirm -- should avoid outdoor activity around noon, and asked local authorities to take precautions against fires that may come from excessive power loads for air conditioners.
