The Korea Meteorological Administration issued a cold weather warning for most areas of the country on Tuesday, saying that the cold snap would continue through early next week.
Warnings about heavy snow, wind chill and high seas were issued for Gyeonggi, Gangwon and Jeolla provinces Tuesday afternoon.
The KMA issued warnings citing a sudden drop in temperature and possible damage caused by the cold snap throughout this week.
The morning low in Seoul hit minus 8.4 degrees Celsius on Tuesday. But the freezing wind chill lowered the actual temperature people feel outdoors to as low as minus 14.3 degrees Celsius.
The wind chill temperature is the rate of heat loss on the human body due to a sudden drop of the temperature and strong wind.
The daytime high recorded minus 3 to 5 degrees Celsius, lower than that of Monday and the seasonal average.
Incheon, Suwon, Daegu and Busan also saw negative single digit temperatures on Tuesday morning, ranging from minus 6.7 degrees Celsius to minus 1 degree Celsius.
The KMA said that although the skies began to clear up after the snow flurries on Monday, rain clouds will gradually move in on Wednesday, with chances of rain predicted at 60 to 80 per cent in Seoul, Gyeonggi Province and Gyeongsang Province.
Weather forecasters encouraged people to use public transportation instead of driving as certain roads may become slippery. Another wave of snowfall is expected in Chungcheong Province and Jeolla Province early Wednesday.
Areas such as Cheongju in North Chungcheong Province and Gwangju in South Jeolla Province saw an accumulation of 6 centimeters of snow. Jeongeup in North Jeolla Province saw about 18.5 centimeters of snow on Monday.
The KMA said the peninsula is under the influence of yellow dust carried by strong wind from northern China.
Areas including Seoul, Gyeonggi Province and Gangwon Province are likely to experience dusty air for the next couple of days.
