Highlights

http://www.pc.gc.ca/apps/scond/Cond_E.asp?oID=19299&oPark=100092Avoid ice climbs with overhead hazard if the day time heating increases. Wind slab pockets are still lurking in the alpine and could be triggered.

Avalanche problems

  • Wind Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Possible
    Size
    1–2
    Caution in shallow and unsupported areas where wind slab has formed.

  • Deep Persistent Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Possible
    Size
    2–4
    Cornice failures or skier travel in shallow snowpack areas are likely ways to trigger this deep weakness in the snowpack.

Weather Forecast

Above seasonal temperatures in the next few days with daytime temperatures to 3 degrees above zero and below freezing at night. Little snow expected and light winds from the north and northwest are forecasted.

Snowpack Summary

Up to 50cm of more settled snow and several different crusts to near tree line elevations provide a lot of support and good travel in the upper snowpack. These firmer upper layers are resting on 50-75cm of weak, poorly bonded faceted snow crystals. Large loads like surface slides or cornice collapses could possibly trigger the upper snowpack.

Avalanche Summary

No new avalanches were observed or reported today.

Confidence

Timing or intensity of solar radiation is uncertain on Thursday
