On Tuesday the 9th, the whole country is expected to be mostly cloudy, with heavy snowfall mainly in the central inland areas, eastern Jeonbuk, and inland Gyeongbuk.

Starting at dawn, rain or snow will begin along the western coast of Gyeonggi, northern inland Gyeonggi, northern inland and mountainous areas of Gangwon, and the northern western coast of Chungnam, then expand by morning to include Seoul and other parts of the metropolitan area, as well as central and southern inland and mountainous areas of Gangwon. In the afternoon, precipitation will occur in the central region, Jeolla area, western inland Gyeongsang, and Jeju Island, and by night, snow or rain will fall nationwide.

Especially due to the influence of a developed snow cloud band, the metropolitan area and central to northern inland and mountainous areas of Gangwon will experience very strong and heavy snowfall of 1 to 3 cm per hour from morning until night. Southern inland and mountainous areas of Gangwon, Chungcheong region, eastern Jeonbuk, and western Gyeongbuk are forecasted to have heavy snowfall of 1 to 3 cm per hour from afternoon until early morning the next day.

The expected snowfall accumulation over two days until the 10th is 5 to 10 cm (with some places exceeding 15 cm) in inland Gyeonggi, northern and southwestern inland Gyeongbuk, and northeastern mountainous Gyeongbuk; 3 to 8 cm (with some places exceeding 10 cm) in Seoul, Incheon, western coastal Gyeonggi, eastern coastal Gangwon, inland Daejeon, Sejong, and Chungnam, central and southern Chungbuk, eastern Jeonbuk, and mountainous Jeju; 5 to 15 cm (with some places in Gangwon mountains exceeding 20 cm) in inland and mountainous Gangwon and northern Chungbuk; 1 to 5 cm in western coastal Chungnam, western inland Jeonbuk, inland central and southern Gyeongbuk, eastern coastal Gyeongbuk, and inland Ulsan and Gyeongnam; and 1 to 3 cm in eastern inland Jeonnam. The western coastal Jeonbuk and central inland Gwangju and Jeonnam will also see around 1 cm of snow.

Morning temperatures will rise by about 3 to 8 degrees compared to the 8th, similar to the average (morning lows between -12 and 0 degrees Celsius, daytime highs between 1 and 8 degrees Celsius), but it will still be cold with temperatures below -5 degrees Celsius mainly inland (around -10 degrees Celsius in inland and mountainous Gangwon).

Fine dust levels are expected to be 'Good' to 'Moderate' nationwide due to smooth atmospheric dispersion.

Sea waves will be 0.5 to 2.0 meters in the East Sea coastal waters, 0.5 to 1.5 meters in the West Sea coastal waters, and 0.5 to 1.0 meters in the South Sea coastal waters.

Wave heights in the offshore waters (about 200 km from the coastline) are expected to be 1.0 to 2.0 meters in the East Sea, 0.5 to 2.5 meters in the West Sea, and 0.5 to 2.0 meters in the South Sea.
