Stormy weather continues until Friday morning. It's a good time to avoid wind affected terrain, like ridgelines and gully features, as reactive wind slabs continue to form.
Wind slabs remain reactive. While new windslabs will continue to form as long as the stormy weather continues. Deep wind slabs have formed, up to 100 cm and could create a very destructive avalanche if triggered. This is a good time to avoid avalanche terrain that has been exposed to recent winds. Riding quality will be best in wind sheltered areas.
No reports of recent avalanche activity. Although it is likely natural wind slab activity continues at higher elevations until the snow and winds taper by Friday morning.
