Rain or snow will fall frequently in many parts of the country through this weekend. There is a chance of rain or snow along the East Sea coast on Friday, in the central inland on Saturday, and along the southern West Sea coast on Sunday.
The Korea meteorological Administration said in a forecast briefing on the 11th, "Today, snow will expand in order to the Gangwon mountains, the East Sea coast, and the northeast mountains of North Gyeongsang," and added, "Tomorrow, temperatures will drop sharply, so much of today's rain will freeze and create icy roads, and road traffic safety requires caution."
The expected snowfall on the 11th–12th is 3–8 centimeters in the Gangwon mountains and the East Sea coast. In some places, more than 10 centimeters could fall. The Korea meteorological Administration plans to issue a heavy snow preliminary advisory at 6 p.m. today for Gangneung, Donghae, Samcheok, Sokcho, Goseong, and Yangyang lowlands in Gangwon, and for the northern, central, and southern mountains of Gangwon. The snow falling toward the East Sea coast is expected to be "wet snow" (濕雪) saturated with moisture. Wet snow is heavy and has a high potential to damage facilities, so preparations are needed.
On Saturday the 13th, rain is expected nationwide. However, strong snow is expected in central inland regions such as Seoul, where temperatures will be low. Unlike on the 4th, when very heavy snow fell in a short time, the Korea meteorological Administration expects strong snow to fall for a relatively long period on the 13th.
The Korea meteorological Administration said, "There is a possibility that a heavy snow advisory will be issued across a wide area of the central inland." On the 13th, 1–5 centimeters of snowfall is expected in areas including Seoul, Gyeonggi, and Incheon, and 5–10 centimeters in the Gangwon inland and mountains. However, it said, "Depending on the temperature profile, rain rather than snow may fall, so snowfall amounts are highly variable."
On Sunday the 14th, snow will fall mainly along the West Sea coasts of South Chungcheong and Honam. Strong winds and high seas are expected that day. The Korea meteorological Administration said, "People planning to visit Jeju Island or the island regions of South Jeolla should be cautious, as strong winds and high waves are expected that could disrupt ferry routes and flights."
Next week will be about 3 degrees warmer than average, but it will still feel chilly as highs remain in the single digits. In Seoul next week, the expected low is -2 to 2 degrees, and the high is 3 to 9 degrees. There is a chance of rain or snow in the central region on the 16th and in the Yeongdong region of Gangwon on the 17th.
