Avalanche risk
The risk of avalanches is greatest on leeward slopes where snow accumulates, especially on slopes with an incline of 25 degrees or more. Cornices that form along ridgelines are extremely dangerous and should never be stepped on or passed beneath. The risk increases during heavy snowfall, strong winds and rapid temperature changes, as unstable snow layers can form. To reduce the risk, avoid the middle of large snowfields and instead follow ridges, higher ground and rocky terrain.
Wind chill effect
Wind is one of the natural forces you need to take extra care with when in the mountains during winter. Here we explain wind strength and give an idea of how wind speed can affect your planned activities. In winds above 11–13 m/s, those without mountain experience should avoid heading out. At 18–24 m/s, visibility is extremely poor and it becomes very difficult to move, even on skis and with the wind behind you. At this point, no one should be out in the mountains.
