    A final pulse of snow and wind has been building up new storm slabs in the alpine. Aside from slab problems, expect small loose wet avalanches to release either naturally or with human triggering on steeper, sun-exposed slopes.

Snowpack Summary

After a period of light rain, new snow has begun to accumulate on the surface. Up to 15 cm of new snow can be expected in the alpine and the depth and reactivity of new storm slabs will likely increase with elevation. The new snow is accumulating on a variable surface of wet snow and crust.Below the surface, the overall snowpack is well settled and strong. New cornices formed and old ones grew more overhanging with the snowfall at the end of last week. Cornices become more unstable as the temperature rises and as they are loaded by rain and new snow.
