You'd better bring out a thick winter coat.
As the cold wind gets stronger overnight, tomorrow (the 5th) will be colder than today. The temperature in Seoul will drop to minus 7 degrees Celsius, and the feeling of cold even in the middle of the day is expected to be below freezing.
This cold wave will gradually ease from the day after tomorrow.
The atmosphere is dry.
A dry warning is in effect in the east coast of Gangwon while dry warnings have been expanded across the country.
As the effective humidity is low in the cold, the risk of fire is high, so please take good care of the embers.
There will be no special rain or snow forecast tomorrow, and only clouds will pass in the sky.
However, in the west coast region, there will be a light snowfall at one time late at night.
For the time being mostly sunny, the cold will gradually ease.
