On Sunday, the 13th, rain is expected in various regions across the country. The metropolitan area will gradually enter a lull from the afternoon. Fine dust levels will be poor due to the yellow dust influx in the morning.
According to the Korea Meteorological Administration, strong winds are expected in most areas of the country due to the influence of a pressure trough passing through the north, with high waves in most maritime regions.
Expected rainfall is ▲Busan, Ulsan, the southern coast of South Gyeongsang Province, the southwestern inland of South Gyeongsang Province, the southern coast and eastern inland of South Jeolla Province, and Jeju 20–60 mm ▲Seoul, Incheon, Gyeonggi, Gwangju, South Jeolla, and inland South Gyeongsang Province 10–40 mm ▲North Chungcheong, South Chungcheong, and northwestern and northeastern inland of North Gyeongsang Province, and northeastern mountainous areas of North Gyeongsang Province 10–30 mm ▲Five Islands in the Yellow Sea, inland and mountainous areas of Gangwon, and northern Jeju 5–30 mm ▲Ulleungdo and Dokdo 5–20 mm.
Expected snowfall amounts are ▲3–8 cm in the mountainous areas of Gangwon ▲1–5 cm in the inland of Gangwon ▲around 1 cm in northwestern and eastern Gyeonggi, Sejong, northern inland of South Chungcheong, central and northern inland of North Chungcheong, and northern inland and mountainous areas of North Gyeongsang Province.
Heavy snowfall is likely to occur mainly in the mountainous areas of Gangwon in the early morning, which may warrant a heavy snow warning. In some areas where rain or snow is falling, gusts and thunder and lightning may also be observed.
However, many areas in the metropolitan area, inland and mountainous regions of Gangwon, and North Chungcheong will show a lull. The southern regions will have occasionally cloudy skies, while Jeju is expected to be generally clear.
Temperatures will be 2–8 degrees lower than average (minimum 3–9 degrees, maximum 15–19 degrees). The morning low will range from 0 to 8 degrees, and the afternoon high will range from 8 to 16 degrees.
Fine dust concentrations will vary from moderate to poor levels. In particular, in the morning, the influx of yellow dust will raise fine dust levels nationwide. The Chungcheong, Honam, Yeongnam, and Jeju regions are expected to experience poor levels, while other areas are expected to remain moderate.
