Issued: Jan 27th, 2024 4:00PM

The alpine rating is considerable, the treeline rating is moderate, and the below treeline rating is moderate. Known problems include Storm Slabs and Loose Wet.

Warm temperatures and rain may be overloading buried weak layers. Use extra caution if entering avalanche terrain today.




Avalanche Summary

Friday: Size 1 and 2 loose wet, and wet slab avalanches were observed in the alpine out of lee features.

Several small (size 1) loose wet avalanches were also observed in the Shames Mountain backcountry.

Thursday: Two small (size 1) natural and rider triggered wet slabs were observed.

Snowpack Summary

10-20 cm of snow has fallen in region over the last week. This snow is likely very dense, settling rapidly, and moist or wet at treeline elevations and below, where some of this snow fell as rain.

A layer of surface hoar and facets has been found around 30-50 cm deep in some parts of the region. Below this sits a 15 cm thick hard crust. There is potential for the accumulated storm snow / rain and warm temperatures to overload these layers triggering large avalanches.

Terrain and Travel Advice

  • Continue to make conservative terrain choices while the storm snow settles and stabilizes.
  • Storm slabs in motion may step down to deeper layers resulting in large avalanches.
  • As surface loses cohesion due to melting, loose wet avalanches become common in steeper terrain.


Storm Slabs

An icon showing Storm Slabs

These slabs will be most reactive at or near ridge crests, especially during periods when snow is being moved by wind onto lee slopes. Wet slabs are possible at treeline elevations and below.

Aspects: All aspects.

Elevations: All elevations.



Expected Size

1 - 2.5

Loose Wet

Use caution when encountering moist or wet snow in steep areas or gully features.

Aspects: All aspects.

Elevations: Treeline, Below Treeline.


Very Likely

Expected Size

1 - 1.5
