The National Meteorological Center Monday evening renewed a yellow alert for a cold front across the country.

From Tuesday to Wednesday, the temperature is expected to drop by 6 to 8 degrees Celsius in northern, northeastern, central and southern China, including parts of Inner Mongolia and Yunnan.

From Monday to Saturday, most places south of the Yellow River will see temperatures 4 to 6 degrees Celsius lower on average than previous years.

The lowest temperatures in parts of Shaanxi, Henan, Hubei and Anhui could reach minus 10 to minus 15 degrees Celsius, or lower, breaking historical records.

China has a four-tier color-coded weather warning system, with red representing the most severe, followed by orange, yellow and blue.
