Highlights

The snowpack has doubled in depth with the last storm and you can expect it will behave very differently from the previous snowpack. Step-out very cautiously and incrementally before committing to bigger terrain.

Avalanche problems

  • Wind Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Possible - Likely
    Size
    1–2
    Moderate - strong SW winds, and significant amounts of snow available for transport. Avoid lingering in run-outs where active loading is happening and/or where there is no evidence of recent previous activity

  • Deep Persistent Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Possible
    Size
    1.5–4
    The new snow seems to be bonding well to the old snow interface. In deeper snowpack areas, this deep weakness may be bridged by a sturdy new mid-pack. Build trust slowly in the new snowpack before committing to any large rideable slope.

Weather Forecast

Sun, wind and warm temperatures to dominate the forecast over the weekend. A detailed mountain weather forecast is available from Avalanche Canada.

Snowpack Summary

Low density storm snow settling into a uniform, mid-pack slab over the deep persistent weakness at the bottom of the snowpack. In deeper areas this mid-pack will continue to settle and in some cases you'll find it bridges the weakness. This might not be the case in shallow, windswept areas at TL and above. Surface condition will vary with exposure.
