When you go travel to Gangwon-do this week, be careful of the snow.

눈요? 아직 눈이 올 만큼 춥지 않은데요.
Snow? It’s not cold enough to snow yet.

강원도는 산악 지형이어서 한국에서 가장 먼저 겨울이 와요. 주말에 대설주의보가 내렸더라고요.
Gangwon-do is where winter comes first in Korea because it has a mountainous region. There was a heavy snow advisory for the weekend.

Come to think of it, most of the ski resorts in Korea are located in Gangwon-do, right?

네, 차갑고 습한 겨울바람이 높은 산을 만나면 많은 눈을 내리게 된대요. 그래서 다른 지역에 비해 적설량이 많지요.
Yes, it is said that the cold, humid winter wind can bring down a lot of snow when they meet the high mountains. That is why there’s more snow than other regions.

그렇군요. 여행을 갈 때 월동 장비를 잘 준비해서 가야겠어요.
I see. I should well prepare passing-the-winter equipment when I go on a trip.
