The cold is at its peak on January 8.
The Korea Meteorological Administration said on the 7th of January that the morning low will drop by 5 to 7 degrees from the previous day as the cold peaks on the 8th, and most parts of the country will see a distribution of less than minus 10 degrees.
The central inland, eastern North Jeolla Province, and northern inland of North Gyeongsang Province are expected to be below minus 20 degrees Celsius, while other central regions, western North Jeolla Province, northern South Jeolla Province, and western Gyeongsang Province are expected to be below minus 15 degrees Celsius.
The Korea Meteorological Administration (KMA) said that outdoor workers such as select clinics and elderly people should pay special attention to health care as daytime highs in the Seoul metropolitan area, Yeongseo in Gangwon Province, Chungcheong and Jeolla provinces, and Gyeongbuk provinces stay below minus 5 degrees Celsius.
The morning lows on the 8th are expected to be minus 26 to minus 9 degrees Celsius, and daytime highs are expected to be minus 12 to minus 1 degree Celsius.
The temperature will rise slightly from the 9th, but the cold will continue for the time being except for the 13th to 14th, when the morning temperature will continue to below minus 10 degrees Celsius until the 10th and the temperature will rise temporarily next week.
As of 4 p.m. on the same day, the Jeolla region, the southwest coast of South Chungcheong Province, and Jeju Island, where the heavy snow warning took effect, had 1 to 3 centimeters of snow per hour.
As cold air moves south into the West Sea, it snows until the 9th in Chungcheongnam-do, Jeolla-do, and Jeju-do due to the influence of the cloud band.
The west coast of Jeolla Province and Jeju Island will have long-term snow until the 10th, but snow intensity is expected to weaken from the 9th.
Snowy areas can have shorter visibility and many places where icy roads appear as snow piles up or freezes.
