South Korea gets rare yellow snowfall

South Koreans were treated to a rare weather phenomenon on Monday 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. 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 rare. The agency said the yellow snow was a health hazard and officials have warned that the pollutants in the flurries included heavy minerals.
