Travel and Terrain Advice
Beware of point-generated avalanches caused by snow with weak coupling. If there is a slope, it also occurs in the forest. Even if an avalanche is small, it can be fatal if it is scooped underfoot and crashed into a tree. When raising the elevation, please pay attention to the wind conditions. Very soft storm slabs are starting to form. When visibility is poor, be especially vigilant about the presence of outbreaks above you.
