Light snowfall has now buried the Dec 11 surface hoar layer. S-SW winds have recently formed windslab on ALP lee slopes. Cold temps and clear skies have faceted the recent snow surface. The Dec 5th surface hoar is down +/-40cm and is stubborn in tests. The Nov 23rd surface hoar/crust/facet combo is down +/-100cm and is becoming stubborn in tests.

Problems
Persistent Slabs
The November 23rd layer consists of surface hoar at and below treeline and a crust on steep solar aspects into the alpine. This layer can be found down 80-100cm.
- If triggered the storm/wind slabs may step down to deeper layers resulting in large avalanches.
Aspects: All aspects.
Elevations: All elevations.

Expected Size
Wind Slabs
Recent S-SW winds have formed windslab in the immediate lee of alpine terrain features. Light overnight storm snow will have obscured these slabs.
- Be careful with wind loaded pockets, especially near ridge crests and roll-overs.
- Use caution in lee areas. Recent wind loading has created wind slabs.
Aspects: North, North East, East, South East, North West.
