Though weather conditions will not have a major impact on road traffic during the holiday, Pei Shunqiang, deputy director at the China Meteorological Administration's public meteorological service center, warned motorists to be mindful of rainy and snowy weather in the northeast.

According to the Ministry of Transport, many people will start returning to work at that time, so more people are expected to be on the roads that day.

Pei said that owners of new energy vehicles should charge their cars in advance, and energy departments should strengthen inspections of electrical facilities and guarantee that power supplies are stable.

Zhang also warned of the potential risks of intermittent fog or haze to travelers in North China, the Yellow River-Huaihe River region and the coastal areas of South China during the holiday.

Due to global warming and the El Nino phenomenon, China has experienced higher temperatures and more extreme climate conditions in recent years.

The country's average temperature last year was 10.71 C, 0.82 C higher than normal and the highest since 1951. Floods and droughts were prominent, though last year's precipitation level was the second lowest since 2012, according to the annual China Climate Bulletin that was issued by the China Meteorological Administration on Wednesday.
