High Alpine: Above 2000m
Alpine: 1000 to 2000m
Low Alpine: Below 1000m
Description:
There is just a low risk of avalanching around the ski area backcountry but deeper into the forecast area on terrain near the main divide there will have been enough new snow and wind to create a moderate danger from windslab avalanching on the SE 1/4. Watch out for signs of instability such as fresh avalanches, tension cracks underfoot or a hollow drummy feel to the snowpack, and if there is more than a few cms depth of new snow or slab buildup avoid crossing steep terrain with poor runouts.
