The Korea Meteorological Administration noted that starting from the afternoon of the 12th, yellow dust from China is expected to flow in. The yellow dust originated from the Gobi Desert and Inner Mongolia the previous day and is flying towards the Korean Peninsula with the northwesterly winds. The yellow dust is expected to cover the entire country overnight, starting from the five islands of the West Sea and the western coast of Gyeonggi.
The concentration of fine dust will also increase. On this day, fine dust levels are expected to be 'bad' in the metropolitan area and Chungnam. On the 13th, 'very bad' levels are predicted in Incheon, Sejong, Chungbuk, and Chungnam, while other areas will see 'bad' levels. On this day, light rain is expected in Jeju (5 mm) and the metropolitan area and Gangwon (1 mm). However, the small amount of precipitation will not be enough to wash away the yellow dust and fine dust.
Yellow dust can cause respiratory diseases, conjunctivitis, dry eyes, and dermatitis. The Korea Meteorological Administration advised people to refrain from outdoor activities and wear masks when going out. After returning home, hands, feet, eyes, and nose should be washed with running water. It is recommended to ventilate indoor air after the yellow dust has passed.
The large temperature difference in the transitional season will continue. According to the Korea Meteorological Administration, the minimum morning temperatures are forecasted to range from minus 3 degrees to 7 degrees on the 13th, and from minus 2 degrees to 7 degrees on the 14th. The maximum noon temperatures are expected to rise from 11 degrees to 17 degrees on the 13th, and from 11 degrees to 19 degrees on the 14th.
