With more wind moving more snow today, natural avalanches are possible and human-triggered avalanches of wind-drifted snow are likely in steep, drifted terrain. Very strong winds over the last couple of days loaded snow onto leeward terrain, creating thick wind slabs and building out already large cornices. Yesterday, we noticed these wind slabs were fairly stubborn. They may be hard to trigger but consequences remain the same if you do set one off.
- Watch for and avoid stiffer wind drifts on the lee side of major ridges, on corniced slopes, and in and around terrain features like cliff bands, sub-ridges, gully walls, and mid-slope rollovers.
- Stiff wind slabs could be stubborn, allowing a person to get far out on them before releasing. Softer wind slabs forming today may be sensitive.
- Cornice fall could trigger wind slab avalanches on slopes below.
- Stay well away from and out from under overhanging cornices, which may break further back and be much larger than expected.
