If you can brave the cold, places to be mindful are lee areas in the alpine, where fresh windslabs may exist. Based on the cold temps and minimal precip over the next few days, little change is expected in the danger rating.

A well settled midpack overrides a weaker facetted base. This weak base is found most places except the west side of the divide. Beware of steep shallow snowpack areas (where the likelihood of triggering this basal layer is highest).

Aspects: All aspects.

Elevations: Alpine.

Likelihood

Unlikely - Possible

Expected Size

2 - 3
