The weak base of depth hoar is still the major concern. Lower angled terrain is now starting to support and offer good ski travel. Choose conservative routes and enjoy your weekend! JBW

Avalanche Problems
Persistent Slabs
Avalanches on the weak base of depth hoar and facets can easily be triggered with just slight additional load. Wind and skier triggered avalanches up to size 2.5 have occurred on all aspects in the last 48 hrs. Avoid steep wind effected terrain.
Aspects: All aspects.
Elevations: Alpine, Treeline.
Likelihood: Likely
Expected Size: 2 - 3
Wind Slabs
Westerly winds with gusts to over 125 km were recorded in the last 24 hrs. These winds were responsible for a fresh cycle of avalanche activity when the wind transported snow overloaded the weak base of depth hoar and full depth slabs released.
Aspects: All aspects.
Elevations: Alpine, Treeline.
Likelihood: Likely
Expected Size: 2 - 3
