Watch for changing conditions as you shift aspect and elevation. A thick crust exists at lower elevations, but wind slabs may build near ridgelines.
New snow accumulations in high alpine areas may remain reactive to human triggers. This problem won't exist where a crust exists on the surface.
Natural wind slabs have been observed over the past 3 days to size 2. However most activity was noted to be size 1, with limited propagation. We expect these conditions to continue with new snow on Monday night.
Light snowfall is expected overnight, favouring the higher elevations with up to 25 cm possible by Tuesday morning.
Below 1000 m the snowpack is likely firm and capped by a crust or saturated snow. Average treeline snow depth is 70 to 150 cm. The snowpack tapers rapidly with elevation, especially on south facing slopes.
