The picture you see is today (23rd) of Deogyusan.
At first glance, it looks like white snow, but the ice was frozen and white frost fell. That's why today was really chilly.
However, it is forecast that it will get a little colder tomorrow.
The northern regions of Gyeonggi Province and the northern regions of Yeongseo, where the cold wave advisory is in effect, will drop to below zero tomorrow, and Seoul will stay at 2 degrees in the morning tomorrow and the perceived temperature will remain below zero.
However, this sparkling cold will gradually ease after peaking tomorrow morning.
From daytime on Sundays, the temperature will gradually recover to normal levels.
It will be generally sunny tomorrow and the air will be clean.
However, strong winds will blow on the west coast, the mountains of Gangwon, and Jeju Island, and you should pay attention to the swelling waves on the east coast.
There will be no clear rain forecast for the time being, so the atmosphere will be very dry.
You should be careful about fire.
