Use caution in wind effected terrain, wind slab over facets, surface hoar or a crust remains the primary concern.

Avalanche Summary
Only small dry loose and wind slabs have been reported recently.
Snowpack Summary
Surface conditions are highly variable. Wind effect can be found on exposed slopes. A new crust exists on the surface below 1700 m and likely up to mountain tops on south aspects. In sheltered terrain A new layer of surface hoar overlies soft snow. In the afternoon the snow surface could become moist at lower elevations.
Check out this MIN describing conditions in the region.
A widespread crust exists 25-40 cm below the surface, and surface hoar has been found above the crust in some parts of the region - a dangerous combination anywhere wind slab exists above it. The snowpack is strong and bonded below the crust.
Conditions remain rugged at lower elevations.

Terrain and Travel Advice
- Carefully evaluate steep lines for wind slabs.
- Wind slabs may be poorly bonded to the underlying crust.
- Back off slopes as the surface becomes moist or wet with rising temperatures.
Problems
Wind Slabs
Outflow wind has impacted open terrain on all aspects at treeline and alpine elevations. The resulting wind slabs are bonding poorly to the underlying crust.
Aspects: All aspects.
Elevations: Alpine, Treeline.
