Gangwon Faces Heavy Snow, High Winds as Coastal Seas Disrupt Transport
The Korea Meteorological Administration outlined winter weather impacts for Gangwon Province on the 13th, with mostly cloudy skies and heavy snowfall expected in mountainous areas. The East Coast and higher elevations could see rain or snow through the day. Forecasts indicate snowfall of 5 to 15 cm in the mountains, with some areas exceeding 20 cm, and 1 to 3 cm along the northern and mid-to-southern East Coast on the 13th. Snowfall and rain are expected to total 5 to 20 mm in the East Coast and mountainous regions.
Early morning conditions are expected to bring concentrated snowfall, with rates of 1 to 3 cm per hour and in some areas around 5 cm per hour. Visibility is likely to drop and roads may become slippery, with a risk of black ice in places. Officials urged particular caution for drivers and pedestrians.
Temperature guidance shows morning lows ranging from -2 to 0°C (28-32°F) inland, -5 to -3°C (23-27°F) in higher elevations, and 1 to 4°C (34-39°F) along the East Coast. Daytime highs are forecast at 7 to 11°C (45-52°F) inland, 1 to 2°C (34-36°F) in the mountains, and 6 to 7°C (43-45°F) on the East Coast.
Offshore conditions were also highlighted, with winds in the central East Sea expected to run at 8 to 16 m/s (about 18 to 36 mph) and waves of 1.5 to 3.5 meters (roughly 5 to 11 feet). Such seas can affect ferries, coastal shipping, and other maritime operations.
The forecast noted that fine dust levels are expected to be moderate, or at a normal level, in the region.
Gangwon Province covers both rugged inland mountains and the eastern coast, making it a key area for winter travel and logistics in South Korea. The weather system can disrupt regional travel and supply chains, particularly for road transport and coastal shipping that link the northeast to Seoul and beyond. For U.S. readers, the weather underscores how East Asian winter storms can ripple through global manufacturing, electronics supply chains, and travel networks connected to Korea’s transport hubs and ports. Travelers and businesses with ties to Korea may want to monitor updates from the KMA and local transit authorities as conditions evolve.
