As the Lunar New Year holiday kicks off, South Korea witnesses an abnormally mild first day, with temperatures expected to reach between 9 to 17 degrees Celsius in various locales. However, the forecast also warns of significant levels of fine dust, particularly in the Seoul metropolitan area and Gangwon's Yeongseo region, which are expected to experience 'very bad' air quality. The weather will generally remain cloudy, with potential for light rain in certain areas but clearing later in the day, especially in the south.

The Meteorological Agency has issued specific warnings regarding air quality, indicating that parts of the Chungcheong, Jeonnam, Busan, and Ulsan regions will face elevated pollution levels. Furthermore, thick fog with visibility of less than 200 meters is anticipated in many inland and mountainous areas, requiring caution, especially in driving conditions. The agency emphasizes that areas near bridges, rivers, and valleys may experience even denser fog, along with potential icy patches on roads in colder regions.

With this combination of weather factors, the situation poses challenges for both health and safety, heightening the need for the public to take necessary precautions against hazardous air quality and driving risks. As families gather for the holiday, the contrasting weather elements remind citizens to remain vigilant and adapt plans accordingly.
