Accordingly, starting tomorrow, morning temperatures in inland areas, including Seoul, will drop to the cold wave warning level and the perceived temperature will approach minus 20 degrees Celsius.
In particular, a cold wave warning has been issued in northern Gyeonggi Province, including Paju, and Gangwon-do, as temperatures are expected to drop below -15 degrees Celsius and the perceived temperature will plummet to around -25 degrees Celsius.
A cold wave warning has been announced in most parts of the country, including Seoul.
This cold wave is expected to remain strong and at its lowest level this winter until mid to late this week, so preparations for freeze-up accidents and cold-related illnesses are expected to be on high alert.
There are also concerns that a lot of snow will fall on the west coast, which is affected by topography during the long cold spell.
