South Korea: Adverse winter weather forecast across much of country through at least Jan. 25
Cold temperatures, heavy snowfall, and strong winds forecast across much of South Korea through Jan. 25. Flight disruptions reported.
Event
Extremely cold temperatures, heavy snowfall, and strong winds are forecast across much of South Korea through at least Jan. 25. As of early Jan. 24, the Korea Meteorological Administration has issued cold wave warnings across much of northern and central South Korea, as well as cold wave advisories for much of the rest of the country. Cold wave warnings are issued when the low temperature is forecast to be below -15 C (5 F) for more than two consecutive days, or when the temperature drops sharply and major damage is likely. The cold wave warning came into effect in Seoul at 21:00 Jan. 23, with temperatures forecast to reach as low as -17 C (1 F) in the capital Jan. 24. Strong wind warnings and advisories have also been issued for many coastal areas of the country, and heavy snow advisories are in place across parts of southwestern South Korea.
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.
Transport
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.
Additionally, the winter weather conditions have already caused flight disruptions. Korean Air (KE) canceled dozens of flights from Jeju Island Jan. 23; Jeju Air (7C) has also stated that it will suspend dozens of flights from the island, with the move subject to change based on weather conditions. Further flight disruptions, including delays and cancellations, are likely amid ground stops and deicing operations at regional airports.
Advice
Monitor local media for updated weather information. Check 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 affected areas. Confirm flights. Charge battery-powered devices in case of prolonged electricity outages.
