A chill has tightened its grip on South Korea, delivering widespread frost, freezing wind chills, and the season’s first snow.
The sudden plunge followed a powerful high-pressure system pushing cold Arctic air south from northern China over the weekend, sending temperatures tumbling well below seasonal norms. Morning readings across the peninsula are expected to hold below 10C (50F) all week, with daytime highs sitting as much as 7C below average.
In Seoul, Monday morning dropped to 5.3C (42F) with wind chills dipping to 3.6C (38F) — colder than even an early-December low.
At Seoraksan, temperatures sank to -1.3C (30F) with a wind chill of -8.2C (18F) — and the first snows settled:
Frost advisories are in effect for inland and highland regions of Gyeonggi, Gangwon, North Chungcheong and North Jeolla provinces. Higher elevations in northern Gangwon are expecting additional snow in the days ahead.
