Parts of central and south China will be swept by heavy rain from Wednesday to Thursday, while parts of north China will be hit by smog, said the country's national observatory Tuesday.
The National Meteorological Center (NMC) forecast heavy rain or rainstorms accompanied by thunder in parts of Hubei, Anhui, Jiangsu, Guizhou and Hunan provinces from Wednesday to Thursday.
Light rain or sleet will continue in northwest China's Xinjiang until Tuesday night, said the NMC.
From Wednesday to Friday, smog will envelop Beijing, Tianjin, Hebei, Henan, Shandong and Shanxi due to a weak cold front, while heavy fog will hit some of the regions from evening until morning.
Conditions for the air to diffuse will gradually improve in most of these regions starting Friday night, said the NMC.
