Avalanche Forecast

Issued: Jan 24th, 2022 3:00PM

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

Even though the hazard is moderate, hard wind slabs can be difficult to evaluate, especially in larger alpine features. Your best skiing will be found in sheltered areas.

Weather Forecast

No snow on the horizon but it is still important to dream....

Tuesday: Cloudy with sunny periods and a high of -7c in the alpine. Expect winds to be Westerly at 45km/hr. An alpine inversion is expected which means that it will colder in the valley bottom and warmer up high.

Wednesday: Cloudy with sunny periods with temperatures from -13c to -8c.

Avalanche Summary

Forecasters were in the Aster Lake area today and did not see any new avalanche activity.

Snowpack Summary

A few cm's of snow today from convective flurries. Widespread wind effect and wind slabs in the alpine and open areas at treeline. These hard wind slabs can be tricky to evaluate because they have the potential to propagate but gives someone the impression underfoot that the base is solid. Take the time to dig and evaluate before committing to larger slopes. In sheltered areas you can find up to 15cm of lower density snow that overlies previous surfaces, which gives acceptable skiing. The Dec crust layer is down 100 to 140cm is faceting and produces moderate to hard shears. Forecasters continue to keep a close eye on this persistent weak layer, despite a long spell of minimal activity associated with it. If/when it re-awakens, large avalanches are possible.

Terrain and Travel

  • Be careful with wind slabs, especially in steep, unsupported and/or convex terrain features.
  • Watch for areas of hard wind slab on alpine features.
  • Be aware of the potential for large avalanches due to the presence of a persistent slab.

Problems

Wind Slabs

An icon showing Wind Slabs

The buried wind slab will be hard to trigger but if you are able to get it to go from a thin area, it could produce a large avalanche. Thin wind slabs are also being found along ridgelines. At treeline these slabs may step down to the December crust. 

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood

Possible

Expected Size

1 - 3

Persistent Slabs

This problem primarily exists below 2200m. Dig and evaluate.  

Aspects: All aspects.

Elevations: Treeline, Below Treeline.

Likelihood

Possible

Expected Size

1.5 - 3
