Smog and fog will blanket some parts of China over the next few days, reducing visibility and affecting travel, the country's top meteorological authority said on Sunday.

Parts of Beijing and Tianjin municipalities and Liaoning, Jilin, Heilongjiang, Hebei, Shanxi, Shandong, Henan and Hubei provinces will be shrouded in light to moderate smog on Sunday. Meanwhile, some areas will see thick haze, according to a statement issued by the National Meteorological Center.

The smoggy weather is expected to gradually weaken and dissipate from November 3, the center said.

Heavy fog is also expected to hit parts of Jiangsu, Anhui, and Sichuan provinces over the next three days, reducing visibility to less than 200 meters, the center said, while advising drivers to turn on fog lights to ensure safety.
