Even today (the 10th), a mask that blocks even fine dust is essential.



Currently, the concentration of ultrafine dust in Seoul, Gyeonggi, North Chungcheong and Sejong has soared to a very bad level.



Today too, the concentration of ultrafine dust will fluctuate between bad and very bad levels across the country, and there are places where there is a lot of haze during the day, so you need to take good care of your respiratory system.



At night, the cold air will come down and the dust will dissipate, but the cold will come instead.



Both morning and day temperatures today will start similarly to yesterday, but with a strong chill coming down tomorrow, the morning temperature in Seoul will drop to minus 9 degrees and the next day to minus 12 degrees.



You must be well prepared for the cold.



Also, in the cold, there is snow in various parts of the inland.



In most cases, the amount will be small, but up to 30 cm or more is expected in the mountainous regions of Jeju, and in the mountainous regions of Gangwon, the west coast of South Chungcheong, and the west coast of Honam and Jeju, up to 5 cm of snow is expected.
