But the snow which is said to contain dust or sand from the desert regions of northern China, could pose a health hazard, the country's meteorological office has warned.

"It's tough to say whether it's yellow sand mixed in snow or if it's snow mixed in yellow sand," a met official said.

A high concentration of dust particles in the snow prompted the weather bureau to issue a yellow dust warning for the second time in three days.

South Korea frequently gets sand or dust storms, but a yellow snow storm is very rare.

"I have never seen yellow snow falling before," the met official said.

The yellow snow is a health hazard, and officials have warned that the pollutants in the flurries include heavy minerals.
