Temperatures in Guangdong dropped to their lowest levels for the same period in more than 30 years last week, according to Guangdong Meteorological Center officials.
Temperatures in northern Guangzhou dropped to minus 3 to 1 degrees Celsius and on the expressway linking Beijing to Zhuhai, temperatures dropped to minus 5.3 degrees Celsius.
The freezing weather caused traffic to pile up on the north Guangdong section of the Beijing-Hong Kong-Macao expressway after it reopened last Thursday afternoon, said Guangdong's traffic department. Parts of the Beijing-Hong Kong-Macao expressway were covered with ice and were closed, said the publicity department of Yao Autonomous County of Ruyuan.
Authorities issued a yellow warning in five counties and cities in Guangdong, including Lechang, Ruyuan and Yangshan, saying ice on roads could cause traffic congestion. Meanwhile, many northern Chinese cities already hit by the cold front reported the coldest temperatures in a decade.
