Avalanche problems

  • Wind Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Unlikely - Possible
    Size
    1–2

    New thin, soft wind slab to be found in lees in the alpine.

  • Storm Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Possible
    Size
    1–2

    New snow at tree line and lower alpine can be developing as a storm slab with warmer temperatures and minimal wind. Check how well the new snow is bonding to the old surfaces such as crusts.

  • Loose Wet

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Likely

    Warm precipitation and cloud coverage will prevent strong overnight freeze until Monday night. Make sure to investigate the strength of surface crust in the late hours of the day.
