South Korea: Adverse winter weather forecast across northeastern regions through at least Feb. 23

Adverse winter weather conditions are forecast across parts of northeastern South Korea through at least Feb. 23. Snowfall accumulations of more than 10 cm (4 inches) are possible across much of Gangwon and parts of northeastern North Gyeongsang provinces, with accumulations of up to 70 cm (28 inches) possible in mountainous parts of Gangwon. As of late Feb. 20, the Korea Meteorological Administration has issued heavy snow warnings for interior parts of eastern and northeastern Gangwon Province and heavy snow advisories across much of the rest of the affected area. 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.
