In sintesi

Up to 10cm may arrive tonight into Thursday not enough to change the current danger rating. However, if the sun pokes out, destabilization can occur quickly especially on solar aspects.

Problemi valanghivi

  • Wind Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible
    Dimensione
    1–2
    Steady moderate Southwest winds continue to build windslabs and cornices on Northerly aspects. Natural activity is reduced with this problem but be vigilant with as shallow spots or large cornice failures being possible triggers.

  • Persistent Slabs

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

    The buried surface hoar layer 70-120cm down remains a concern in areas that have not avalanched. Whumphing is still being observed on isolated North shaded glades below treeline. Be cautious of this layer as triggering it would be high consequence.

  • Loose Wet

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

    Cloud cover today reduced daytime heating but anytime the sun pokes out, loose wet avalanche activity will increase. Expect this activity originating from steep S or W aspect rock bluffs or gullies starting mid afternoon.
