Problemi valanghivi

  • Wind Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible - Likely
    Dimensione
    1–3
    Up to 20cm of new snow will be reactive where it sits over sun crusts, as well as temperature crusts on shady asp. from high freezing levels earlier in the week. Caution is advised until the bond improves. Light snow Sat. at higher elevations.
  • Loose Wet

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible
    Dimensione
    1–2
    Forecasts call for light rain tomorrow at treeline and below, and wet slides will be still possible if this comes to fruition.
  • Deep Persistent Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Unlikely - Possible
    Dimensione
    1–3
    Some slides occurred in the last 24 hours to 2.5 which gouged down to the basal facets during the rain. Activity will slow down as temperatures cool. Thin, steep areas and large loads such as cornice failure could possibly trigger deep weaknesses.
