On the 4th, a Saturday, morning temperatures fell below minus 10 degrees Celsius in the interior and mountainous areas of Gangwon, where a cold wave warning was in effect. Strong winds made it feel even colder.
Temperatures are similar to the average (lowest -12 to 0 degrees, highest 1 to 9 degrees).
As of 6 a.m. that day, morning temperatures by region were: ▲ Seoul -4.9 degrees ▲ Incheon -4.0 degrees ▲ Suwon -6.2 degrees ▲ Chuncheon -10.1 degrees ▲ Gangneung -4.2 degrees ▲ Cheongju -2.5 degrees ▲ Daejeon -3.0 degrees ▲ Jeonju -0.8 degrees ▲ Gwangju 0.5 degrees ▲ Jeju 6.8 degrees ▲ Daegu 0.1 degrees ▲ Busan 0.1 degrees ▲ Ulsan -1.3 degrees ▲ Changwon 0.6 degrees.
The highest daytime temperatures by region were forecasted to be: ▲ Seoul 5 degrees ▲ Incheon, Suwon, Chuncheon 4 degrees ▲ Gangneung, Daejeon, Cheongju 6 degrees ▲ Gwangju, Busan, Ulsan, Changwon 8 degrees ▲ Jeju 10 degrees.
The elderly and young children, who have weaker immune systems, should refrain from outdoor activities as much as possible and take care of their health due to the rapid temperature changes and low temperatures.
The cold wave warnings for the inland areas of northern Gyeonggi and Gangwon's interior and mountainous regions are expected to be lifted that day.
Until morning, there might be areas in the interior of South Chungcheong and North Jeolla with fog reducing visibility to less than 1 km. In particular, roads adjacent to rivers, lakes, and valleys may experience denser fog, so traffic safety should be observed.
The fine dust level is expected to range from 'good' to 'moderate' across all regions due to smooth atmospheric diffusion.
