Highlights

Highway 93 is closed with an uncertain opening date.

A large amount of precipitation has fallen in the icefields area as a mixture of snow and rain. At higher elevations this will add a large volume of snow as a storm slab and on top of existing weak layers. Carefully asses all terrain and be mindful of exposure to overhead slopes.

Avalanche problems

  • Persistent Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Likely
    Size
    1–3

    A 40-100cm slab existed previously and is now being overloaded by new precipitation. This may be the tipping point for some slopes.

  • Storm Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Likely - Very Likely
    Size
    1–2.5

    Continued precipitation has created a storm slab at higher elevations. Around the Bald Hills area expect them to be 20-30 cm deep at higher elevations.
