Precipitation: Nil.
Alpine temperature: High -2 C.
Ridge wind west: 10-20 km/h.

1 size 1.5 Steep N aspect alpine, cornice triggered windslab that appears to have stepped down to a persistent layer.
Confidence
Problems
Wind Slabs
Continued winds Tuesday redistributed recent storm snow to lee features combined with new snow, and warm temperatures.
- Watch for whumphing, hollow sounds and shooting cracks.
- Use caution in lee areas in the alpine and treeline. Recent storm snow has formed wind slabs.
Aspects: North, North East, East, North West.
Elevations: Alpine, Treeline.
Likelihood
Expected Size
Persistent Slabs
New load with warm temps could increase the likelihood of triggering.
- Carefully evaluate terrain features by digging and testing on adjacent, safe slopes.
- Note recent avalanche activity.
Aspects: North, North East, East, North West.
Elevations: Alpine.
Likelihood
Expected Size
