Continue to use caution as the skiing slowly improves, human triggering of the Persistent and Deep Persistent avalanche problems remains possible.
Summary
Confidence
Avalanche Summary
No new avalanches were observed or reported in the last couple of days.
Snowpack Summary
In sheltered areas 10 - 20 cm of low density snow overlies the Feb 3rd crust, which ranges from 1-3cm thick on shaded aspects up to 2500m, to 15-20cm thick at lower elevations. The Persistent and Deep Persistent weak layers continue to produce whoomphing and sudden fractures in tests.
Weather Summary

Terrain and Travel Advice
- Avoid shallow snowpack areas, rock outcroppings and steep convex terrain where triggering is most likely.
- Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
Problems
Wind Slabs
Moderate to strong winds from the west and northwest have formed new wind slabs in leeward features in the alpine.
Aspects: North, North East, East, South East, South.
Elevations: Alpine.
Likelihood
Expected Size
Persistent Slabs
Our recent melt-freeze cycle was not strong enough to heal our persistent slab problem. This weak layer, buried 20-40cm deep, is still reactive in snowpit tests and human triggering remains possible, particularly in shallow rocky start zones.
Aspects: All aspects.
Elevations: Alpine, Treeline.
Likelihood
Expected Size
Deep Persistent Slabs
The base of the snowpack is inherently weak and untrustworthy. Human and natural triggering of these basal facets remains possible.
Aspects: All aspects.
Elevations: Alpine, Treeline.
