On January 5, 2023, South Korea experienced significant snowfall, with heavy snow warnings issued across various regions, especially the capital area. This weather event coincided with 소한 (Sohan), traditionally one of the coldest periods of the year. Meteorologists warned residents to prepare for challenging weather conditions.
Starting early in the morning, snow began to blanket Seoul and surrounding areas such as Gyeonggi Province and parts of Gangwon Province. According to reports from local meteorological agencies, snowfall accumulation could reach between 1 to 10 centimeters throughout the day, with some areas experiencing heavier snowfall. The South Korean meteorological agency reported, "Heavy snow is predicted across the country, particularly affecting the capital region. A heavy snowfall warning has been issued."
Conditions began to deteriorate as snow continued to fall, turning roads slippery and hazardous for drivers. Areas of Seoul experienced significant snow cover, and warnings were issued to remind people to be cautious as road conditions could quickly become treacherous. A meteorologist advised, "Be cautious as the roads could become very slippery quickly." With temperatures hovering just above freezing and the forecast projecting continued snowfall, drivers were particularly urged to avoid unnecessary travel.
The forecast for January 5 suggested accumulating snow was likely to continue until the evening, with estimates indicating about 3 to 10 centimeters of snow was expected by the time the storm would begin to subside. The maximum expected accumulations were projected to be concentrated mostly in central regions. The stringent weather combined with the typical January chill could lead to even more dangerous driving conditions as temperatures drop.
Residents were reminded of the historical significance of this season, as 소한 is known to herald the coldest weather, and it is said, "대한이 소한의 집에 가서 얼어 죽는다," meaning the coldest weather occurs during this time. Normal morning temperatures were reported at around -1 to 2 degrees Celsius, much warmer than the historical averages.
Authorities emphasized the need for preparedness as the current snowfall could lead to hazardous conditions. Precautions advised included checking the condition of vehicles before heading out, ensuring tires and brakes were functioning properly, and maintaining safe distances on the roads. It was mentioned, "The snowfall accumulation could lead to dangerous road conditions, especially during the early hours of the morning," highlighting the need for vigilance with safety measures.
This snowfall is part of the unusual weather patterns observed this season, and residents have been on alert for any updates on road conditions. The authorities were particularly concerned about the possibility of increased ice formation due to falling temperatures after snowfall. Many citizens expressed their apprehensions about traveling under such conditions and were encouraged to seek alternate transportation or stay home whenever possible.
With snowfall tapering off throughout the evening and some regions expected to see clearing conditions, the adverse weather was expected to shift again next week as forecasters warn of more snow and low temperatures returning. They predicted, "more snowfall is likely next week, so stay tuned for updates."
Until then, citizens are encouraged to stay warm, avoid unnecessary travel, and remain alert to changing weather conditions; safety remains the utmost priority as South Korea navigates this snowy start to the year.
