Avalanche Forecast

Issued: Jan 29th, 2024 4:00PM

The alpine rating is high, the treeline rating is high, and the below treeline rating is considerable. Known problems include Deep Persistent Slabs, Persistent Slabs and Loose Wet.

Avalanche Canada CB, Avalanche Canada


A widespread avalanche cycle is ongoing, and the avalanche hazard will remain elevated until the warm temperatures and high winds subside, or our precious little snowpack melts away.

Avoid all avalanche terrain.




Avalanche Summary

Numerous natural avalanches at all elevations were observed on Monday. Impressive avalanches up to size 3 out of alpine and tree line features, as well as loose wet and wet slabs up to size 2 below tree line were observed.

Snowpack Summary

High freezing levels, mixed precipitation, and intermittent solar radiation has formed surface crusts or moist snow up to 2500 m on most aspects, and higher on steep sun effected ones. Persistent weak layers formed in early January are down 20-30cm in sheltered areas, and have been reactive more recently where wind loaded. Well developed facets and depth hoar make up the bottom of the snowpack.

Weather Summary

It will continue to be unseasonably warm with strong winds for the next couple days. There is also potential for some light precipitation near the icefields, likely a mix of rain or snow depending on elevation.

Terrain and Travel Advice

  • Make conservative terrain choices and avoid overhead hazard.
  • Stick to non-avalanche terrain or small features with limited consequence.


Deep Persistent Slabs

An icon showing Deep Persistent Slabs

The base of the snowpack is inherently weak and untrustworthy. Concern for human and natural triggering of this avalanche problem will increase as the temperatures rise over the next few days.

Aspects: All aspects.

Elevations: All elevations.



Expected Size

1.5 - 3

Persistent Slabs

An icon showing Persistent Slabs

This layer is concerning when there is a cohesive slab overlying it. Watch for the warnings in the snowpack like shooting cracks.

Aspects: All aspects.

Elevations: All elevations.



Expected Size

1 - 2.5

Loose Wet

An icon showing Loose Wet

Watch for this problem to become more significant as the temperatures rise, particularly in steep and rocky terrain.

Aspects: All aspects.

Elevations: All elevations.


Likely - Very Likely

Expected Size

1 - 2
