Travel and Terrain Advice
Very dangerous avalanche conditions. Within the avalanche bulletin area, differences in snowfall will result in different levels of danger. In areas of heavy snowfall, avalanches are possible even in the forests if the slope is steep enough. These are days when even the powder snow in the ski area can be enjoyed. It is a good idea to enjoy the fresh snow in the ski area with your friends.
