Today, Monday (10th), fine dust is thick across the country, and the air is very turbid with fog forming mainly inland.
As of 8:00 a.m., Seoul, Gyeonggi, Chungcheong, Sejong, and Daejeon are 'very bad' and the rest of the region including Jeju is 'bad'.
Ultrafine dust (PM2.5) is 'very bad' in the metropolitan area, Chungbuk, Sejong, and Daegu, 'bad' in all regions except Jeju, and 'average' only in Jeju.
Fine dust (PM10) is 'bad' in the metropolitan area, Chungcheong, Sejong, Daejeon, Gangwon, Gyeongbuk, Jeonbuk, and Daegu, and 'normal' in the rest of the region including Jeju.
Due to the influence of high pressure in the west, the wind was weak and the atmosphere was stagnant, and the concentration of fine dust increased.
There was also fog this morning that lowered the visibility to less than 1 km, mainly inland.
Fog usually disappears around 9-10 am after sunrise, but in some areas, fog remains throughout the morning or when humidity is relatively low, 'haze' will appear during the day, in which fine particles such as dust floating in the air appear cloudy.
The temperature this morning was around minus 5 degrees nationwide.
The daytime temperature will rise to 3-12 degrees.
In the southern regions, the daytime temperature may exceed 10 degrees Celsius.
Due to the low pressure located in the northwest of Korea, cold air below minus 30 degrees Celsius from the northwest moves south, and the pressure valley formed by meeting the warm air is gradually coming south.
Therefore, snow will fall in the metropolitan area, Gangwonyeongseo, Chungnam, and North Chungcheong Province from 6 to 9 pm today.
The snow is expected to extend to all of Chungbuk, Honam, and Jeju between 9 pm and midnight.
Jeolla-do and Jeju-do have high temperatures, so it may rain instead of snow.
Estimated snowfall is Jeju Mountain, Ulleungdo Island, Dokdo 5~20cm (more than 30cm in many places); The inland and west seas are about 1 cm apart.
In the metropolitan area, excluding southern Gyeonggi-do, and inland of southern Gyeongbuk, and inland of western Gyeongsangnam-do, the snowfall is less than 0.1 cm.
The Korea Meteorological Administration urged the Korea Meteorological Administration to be especially careful not to catch fires due to the very dry atmosphere around the Gyeongsang Coast where a dry warning was issued.
