Yellow dust originating from China is blanketing South Korea on Monday, raising concentrations of fine dust particles to very bad levels in most parts of the nation. 
 
The Korea Meteorological Administration(KMA) issued a yellow dust advisory for ten cities and provinces including Seoul at 7 a.m. 

As of 7 a.m., concentrations of ultra-fine dust particles in the capital city, as well as Ulsan, Daejeon and North Jeolla, Gyeonggi and the Chungcheong provinces, rose to "very bad" levels. 

The yellow dust, which originated from the Gobi Desert and Inner Mongolia on Friday, began to enter the Korean Peninsula from Sunday night riding a northwesterly wind. 
 
The Ministry of Environment forecast the nation will see concentrations of fine dust at "very bad" levels on Monday, and the dust will continue into Tuesday. 

The ministry already issued a yellow dust advisory for the nation on Sunday afternoon, advising elderly people to refrain from going outdoors.
