Avalanche Forecast

Issued: Feb 10th, 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.

Fresh snow and a supportive crust (in some places) has improved the skiing.

Look for low angle terrain for the best quality turns, and because the buried weak layers are still untrustworthy.




Avalanche Summary

No new avalanches were observed or reported in the last couple of days. However, our field team reported widespread whumpfing at tree line and alpine areas on Tuesday in the Icefields area. On Monday, the field team triggered a size 1.5 persistent slab on a south aspect at tree line.

Snowpack Summary

10 - 20 cm of recent snow sits over a variable, breakable crust. This crust is 1-3cm thick on shaded aspects, and up to a 15-20cm thick on solar aspects. Big, connected, and sunny tree line features are the most troublesome. Persistent and deep persistent weak layers remain ever-present and active. Do not trust either of these layers.

Weather Summary


Mainly cloudy with isolated flurries.

Precipitation: Trace.

Alpine temperature: High -5 °C.

Ridge wind southwest: 10 km/h.

Freezing level: 1600 metres.

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.



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
