Avalanche Forecast

Issued: Feb 11th, 2024 4:00PM

The alpine rating is moderate, the treeline rating is moderate, and the below treeline rating is low. Known problems include Wind Slabs, Persistent Slabs and Deep Persistent Slabs.

Continue to use caution as the skiing slowly improves, human triggering of the Persistent and Deep Persistent avalanche problems remains possible.




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.


Wind Slabs

An icon showing 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.


Possible - Likely

Expected Size

1 - 1.5

Persistent Slabs

An icon showing 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.



Expected Size

1 - 2.5

Deep Persistent Slabs

An icon showing 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.



Expected Size

1 - 3
