On Monday the 23rd, most regions nationwide will be under the influence of yellow dust, and the morning will be cold due to a cold wave.
According to the Korea Meteorological Administration, as of 7 p.m. on the 22nd, yellow dust originating from the Gobi Desert and the Inner Mongolia Plateau has been observed in North Chungcheong, South Jeolla, North Gyeongsang and South Gyeongsang, and Jeju Island. This yellow dust is expected to affect most regions nationwide on the 23rd as well, leading to high concentrations of fine dust (PM10).
In addition, strong winds will blow in most regions nationwide, and the air will be dry, requiring particular caution to prevent forest fires and other blazes. In North Chungcheong, Busan, and Ulsan, winds will blow very strongly through the morning at around 70 km/h (around 110 km/h in mountainous areas). Skies will be mostly clear nationwide, but from the afternoon there will be occasional clouds.
Morning temperatures on the 23rd will drop by about 5 to 10 degrees from the 22nd, with most regions nationwide expected to fall to 0 degrees or lower. With strong winds, the wind chill will be even lower, making it feel colder. The Korea Meteorological Administration said, "Older adults and children with weaker immune systems should take care due to the rapid temperature changes," adding, "When going out, pay attention to keeping warm by wearing warm clothes and cold-weather gear, and exercise particular caution to prevent fires when using heating appliances such as stoves and electric mats."
The expected morning low is -7 to 3 degrees, and the daytime high is 3 to 13 degrees. By region, the forecast lows are -2 degrees in Seoul, Daejeon, and Jeonju; -6 degrees in Chuncheon; -1 degree in Gwangju and Daegu; 3 degrees in Busan; and 4 degrees in Jeju. As temperatures rise during the day, ice on rivers, lakes, and reservoirs may melt, thin, and crack. As temperatures rise, frozen ground may thaw and weaken, which could cause ground subsidence on roads or at construction sites, and lead to soil runoff, landslides, and falling rocks in mountainous areas and cut slopes, so caution is advised.
