Snow depth in Alt St. Johann

Snow is what makes a ski holiday special. Ideally, we wake up every day to Kaiser weather: a layer of fresh snow, bright sunshine, and a clear blue sky. However, icy temperatures and heavy snowfalls are also part of the experience. Or those foggy days when you ski from hut to hut, warming up with a cup of coffee, tea, or hot chocolate. When it comes to winter sports, the weather can be unpredictable, and nothing changes more rapidly than mountain weather. In addition to the forecast for the coming days, the current snow depth is a key part of the weather report in Alt St. Johann.
