BEIJING -- Heavy rainfall will hit South China over the next three days, the National Meteorological Center (NMC) said on Friday.

The country's weather observatory forecast that torrential rain or even rainstorms will pound southern provinces including Hunan, Jiangxi, Fujian and Zhejiang from Friday to Sunday.

Elsewhere, a cold front on Friday afternoon will disperse smog, which has blanketed North China for days in Tianjin Municipality, and Hebei and Liaoning provinces.
