South Korea: Adverse winter weather forecast across much of the country through Jan. 23

Adverse weather conditions are forecast across much of South Korea, mainly in central, southern, and western parts, as of Jan. 22. A cold wave will likely see minimum temperatures drop to around -12 C (10 F) in Seoul and parts of Gyeonggi and Gangwon provinces through at least Jan. 23. Strong winds and heavy snowfall are also likely in coastal and mountainous areas; reports indicate snowfall accumulations of up to 31 cm (12 inches) in Jeju. Transport disruptions are occurring in worst-affected areas; reports indicate passenger shipping disruptions at Jeju and road closures in tourist areas of Jeju and Gangwon.

As of Jan. 22, the Korea Meteorological Administration has issued the following weather warnings across the country:

• Cold wave warning: Gyeonggi, Gangwon, as well as parts of North Gyeongsang, North and South Chungcheong provinces, Busan, Greater Seoul, Incheon, and Jeonbuk State

• Snowfall warnings or advisories: Much of northern and central South Korea, South Chungcheong, South Jeolla and Gyeonggi provinces, Sejong, Jeonbuk State, Jeju Island

• Cold wave and/or strong wind advisories: Across much of western, southern, and northern South Korea

Authorities will likely issue new alerts or update/rescind existing advisories as weather conditions change over the coming days.

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 may occur 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 likely 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 possible due to potential ground stops and deicing operations at regional airports.
