  • Wind Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Possible
    Size
    1–2
    Currently these slabs are only being found in immediate lees in open wind affected terrain. 

  • Persistent Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Unlikely - Possible
    Size
    1–3
    No activity on this layer in some time but we exepect in the wrong kind of terrain feature it could be an issue.  ie, steep and unsupported at treeline.

  • Deep Persistent Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Unlikely - Possible

    2–5
    Basal facets are a concern in wind affected areas where the snowpack is highly variable

Snowpack Summary

The 10-15cm of recent HST is being redistributed at higher elevations from a SW wind.  New storm slabs are building in immediate lees at higher elevations while snow in most other areas remains undisturbed by winds.  Jan 16th SH and Dec 13th CR are down 30 and 50cm and continue to produce moderate results.
