In sintesi

Mild temps, and light snow in the forecast Monday night will do little to change the overall hazard. Although harder to initiate, large avalanches are still possible to trigger in steep, variable terrain. Good skiing reported. SH

Problemi valanghivi

  • Persistent Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Unlikely - Possible
    Dimensione
    2–3
    The Valentines surface hoar is down 70-150cm. Field tests in numerous areas are finding hard to no results in deeper snowpack areas. The chance of triggering will increase on thin or variable slopes, and large avalanches are still possible.

  • Storm Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible
    Dimensione

    Up to 15cm with winds switching to SW by Tuesday (most in South and East regions) . This will create isolated soft slabs near ridge crests that may be triggered in steeper terrain. Warmer temps will enable the new snow to bond well.

  • Deep Persistent Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Unlikely - Possible
    Dimensione
    1–3
    Although difficult to initiate, it is still possible to trigger a deep persistent slab. Heavy loads in steep, shallow areas are most likely to produce an avalanche on this layer currently.
