    Wind slabs exist in many alpine and open treeline areas. These may be difficult to spot because they have been buried by light new snow.

Avalanche Summary

Small loose dry avalanches and wind slabs have been triggered naturally, by explosives and by skiers recently. Some large cornice chunks have been failing naturally.

Snowpack Summary

New and buried wind slabs may be found in alpine and open treeline terrain. Fragile cornices exist. A couple of storm snow weaknesses have been observed, but these are likely to be short-lived. In sheltered areas below treeline, loose snow is slowly becoming more consolidated. In general, the mid-pack is strong.Near the base of the snowpack, a crust/facet layer is now unlikely to be triggered. However, professionals are still mindful of thin snowpack trigger areas or large loads which could wake it up again, leading to a very large avalanche.
