Conditions are improving but large, unsupported slopes should be carefully evaluated before you commit.

Avalanche problems

  • Persistent Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Possible
    Size
    2–4
    The buried surface hoar layer remains a concern. While natural activity is reduced slopes that did not slide during early March should be treated with extra caution.

  • Storm Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Possible - Likely
    Size
    1–3
    Variable winds in alpine areas continue to form slabs on lee aspects. We've seen 70+cm of new snow since March 12th. Triggering the storm slab has the potential to step down to deeper instabilities.

  • Loose Wet

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Possible
    Size
    1–2
    As the spring season arrives even short periods of direct sun can have dramatic effect on the snow stability on solar aspects. Watch for increased loose snow avalanche activity during the heat of the day.
