South Korea: Adverse winter weather forecast across much of the country through at least Dec. 24

Event

Heavy snowfall and low temperatures are forecast across much of South Korea through at least Dec. 24. Heavy snowfall has already fallen in several areas in recent days and caused disruption to ground and air transport. Further heavy snowfall over the coming days is likely to be accompanied by temperatures dropping to as low as -14 C (7 F) in some inland areas. 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 worst-affected areas.

The Korean Meteorological Administration has issued heavy snowfall warnings for Gwanju City and parts of central and northern South Joella and southern north Joella provinces Dec. 23. Heavy snowfall advisories have been issued across much of eastern, east-central, and southeastern South Korea, including Jeju Island. A cold wave warning has also been issued across northern and central parts of the country, as well as cold wave advisories for much of inland South Korea. Strong wind advisories have been issued for many coastal areas and rough sea warnings and advisories across coastal waters. Authorities will likely issue new alerts or update/rescind existing advisories as the winter storm transits the region over the coming days.

Flight cancelations, road closures, and multiple car accidents were reported amid heavy snowfall in Seoul and eastern and central inland areas of South Korea Dec. 21, as well as on Jeju island. At least 14 flights were canceled across the country and passenger ferries linking the frontline island of Baengnyeong and Incheon, west of Seoul, were also suspended. Authorities reported at least 26 snow-related vehicular accidents and more than 200 schools across the country either switched to remote learning or reduced opening times.

Transport
The winter weather will likely cause ground and air transport disruptions across the affected area over the coming days. Further 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 the affected states as maintenance crews prioritize clearing major routes. Authorities could close stretches of a highway if driving conditions become too hazardous. Gusty winds may threaten to topple high-profile vehicles throughout the affected area. Flight delays and cancellations are likely due to ground stops and deicing operations at regional airports.

Advice

Monitor local media for updated weather information. Verify road conditions before driving in areas where heavy snowfall is forecast. Allow extra time to reach destinations in these areas and carry an emergency kit and warm clothes if driving is necessary, especially on secondary or rural routes that could become impassable. Plan accordingly for delivery delays if routing shipments by truck through the affected area. Confirm flights. Charge battery-powered devices in the case of prolonged electricity outages.
