South Korea: Adverse winter weather forecast across most of the country through at least Nov. 28

Adverse winter weather conditions are forecast across much of northern South Korea through at least Nov. 28. As of Nov. 27, the Korea Meteorological Administration has issued heavy snowfall warnings across southwestern Gangwon, southern Gyeonggi, and far northwestern North Chungcheong provinces as well as Seoul Special Metropolitan City. Heavy snowfall advisories are in place across the rest of northern and central South Korea. Wind warnings and advisories are in place across western, southern, and eastern South Korea. Authorities will likely issue new alerts or update/rescind existing advisories as weather conditions change over the coming days.

One person died and four others sustained injuries in a vehicle accident in the eastern town of Hongcheon. Officials canceled 11 domestic flights and one international flight Nov. 28. Reports indicate the cancellation or delays of at least 220 flights at airports nationwide. Authorities ordered around 90 ferries to remain at port. Seoul's subway Line 9 also experienced delays.

In addition to the wintry precipitation, strong wind gusts could lead to periods of blowing and drifting snow. Blizzard conditions are possible. Sporadic power outages are likely in the most severely affected areas.

The winter weather will probably cause ground transport disruptions across affected areas over the coming days. Hazardous travel conditions are likely due to icy roads, snowfall accumulations, and reduced visibility caused by blowing snow. Traffic and commercial trucking delays are probable along regional highways. Difficult and potentially dangerous driving conditions are also likely on secondary and rural roadways in affected areas as maintenance crews prioritize clearing major routes. Authorities could close stretches of highways if driving conditions become too hazardous. Gusty winds may topple high-profile vehicles. Flight disruptions, including delays and cancellations, are likely amid ground stops and deicing operations at regional airports.
