Travel and Terrain Advice
Beware of instabilities within the new snow and be cautious of the new/old bond. Allow time for the storm snow to settle and bond to the old surfaces before venturing into challenging terrain. Loose dry avalanches can be expected on steep slopes. Along with avalanches deep snow brings the risk of snow immersion incidents. Always ski with a partner and keep an eye on each other to assist in the case of an unexpected fall.
