Highlights

Minimize overhead hazard while the snowpack reacts to the rising freezing levels.

Avalanche problems

  • Wind Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Possible - Likely
    Size
    1–2
    Strong SW winds, and significant amounts of snow available for transport have created wind slab in lee features. 

  • Cornices

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Possible
    Size
    1–3
    Rising freezing levels could result in fresh cornices to fail triggering deep instabilities.

  • Deep Persistent Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Unlikely - Possible
    Size
    1.5–4
    Use caution in shallow snowpack areas where deep weakness might be more reactive to a human load.  Build trust slowly in the new snowpack before committing to any large rideable slope.

Weather Forecast

Sun and rising freezing levels to around 2000m on Sunday. Winds look to be light south-westerly. A detailed mountain weather forecast is available from Avalanche Canada.

Snowpack Summary

Exposed terrain at TL and above have been hammered with wind. In sheltered terrain the snow surface is likely to change with warm temperatures. The upper half of the snowpack is settling into a uniform slab over deep persistent weakness' at the bottom of the snowpack. Use caution in shallow areas where these deep weakness might be more reactive.
