High

Avalanche Summary

No new avalanches have been observed or reported.

Snowpack Summary

The forecast calls for 10-15cm of snow with light North winds by Thursday night. This new snow will rest on the previously settled snow which includes a sun crust on solar aspects. At treeline, an average of 30-40cm of recent snow overlies the Mar 28 crust which carries the weight of a skier. Take the time to monitor the presence of this crust; if it is not there, then there could be a higher likelihood of triggering the basal facets. The Jan 30th layer buried 60 to 100cm deep is still a concern. It could become active with intense heating (daytime temps and/or solar input), and it is also problematic on northern aspects at higher elevations and in shallow snowpack areas. Human triggering is possible as well in these areas.

Weather Summary

Another pulse of snow is to begin Wednesday night and go into Thursday. Hopefully we get 10-15cm by Thursday night. Hot weather is expected to start this weekend.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Keep in mind that human triggering may persist as natural avalanches taper off.
  • Avoid shallow snowpack areas, rocky outcrops, and steep terrain where triggering is most likely.

Avalanche Problems

Persistent Slabs

This layer still persists throughout the region. Be especially cautious at upper elevations where the Mar 28th crust might not have formed (mainly high northerly aspects), and in shallow snowpack areas. Solar aspects are also a concern during periods of intense heating.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 2 - 3.5

Deep Persistent Slabs

Continue to limit exposure to overhead hazard in areas that haven't avalanched,

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 2.5 - 4
