In sintesi

There are widely conflicting weather forecasts, but some models are predicting up to 30 mm of precipitation by Friday. If the storm materializes the avalanche hazard will remain elevated through the end of the week.

Problemi valanghivi

  • Wind Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Likely
    Dimensione
    1–2
    Ten to 20 cm of fresh snow today coupled with strong westerly winds have created fresh wind slabs in the alpine. These winds slabs are reactive to skier triggering and may step down to the deeper surface hoar layer resulting in a very large avalanche

  • Persistent Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco

    The Valentine surface hoar is now down 70-100 cm. Natural activity with this layer is subsiding, however, it is still prime for human triggering. This layer is producing moderate shears in test pits.
