Foggy weather will continue in most of east and central China in the coming three days and is likely to affect the travel rush after the Spring Festival, said the National Meteorological Center (NMC) on Friday.

Light fog will cover many parts of east and central China, causing visibility to decrease to within 200 meters in some areas, said the NMC.

Lin Jian, the NMC's chief forecaster, attributed the prolonged fog to weak cold currents and precipitation in the south.

Local governments must prevent the fog from hampering transport and ensure traffic safety, said the NMC.

Initial investigation showed heavy fog caused a highway crash on Friday, killing a woman and a 6-year-old boy in Guizhou Province, southwest China.
