SEOUL, Mar 13 (Reuters) South Koreans were treated to a rare weather phenomenon today when yellow snow fell in the capital and elsewhere across the country.
But the snow -- containing dust or sand from the desert regions of northern China -- could pose a health hazard, the country's meteorological office 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 told Reuters.
A high concentration of the dust particles 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 agency said the yellow snow was a health hazard and officials have warned that the pollutants in the flurries included heavy minerals.
