Highlights

If the weather forecast is correct, we will see a quick warming trend in the morning. Skies may also be clear so keep an eye out for change.

Avalanche problems

  • Wind Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Possible - Likely
    Size
    1.5–2.5

    Winds overnight will be variable so expect new slabs on almost all aspects. Buried slabs are on all easterly aspects and in many places there are multiple layers.

  • Deep Persistent Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Unlikely - Possible
    Size
    2–3.5

    Large triggers are a concern. Cornices, or other avalanches could wake this layer up. 

Terrain and Travel

  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.

Avalanche Summary

Nothing new today.

Snowpack Summary

Moderate to strong winds last night made short work of the new snow. Lots of exposed ridges in the alpine which means there is some crossloading happening in the alpine and upper treeline. In sheltered areas the snow was still soft, yet slightly disturbed by the wind. Overall the midpack feels well settled and solid at treeline. There is a weak layer(dec31 surface hoar) down 50-80cm, but it seems well bonded. Last week's rain crust is down 20-25cm and obvious in all places below 1950m. So far no problems are associated with this crust.
