Lo esencial

Freezing levels and quality of overnight freeze are uncertain on Friday.  If there is no freeze, danger ratings at treeline will likely be higher than forecast.

Problemas de aludes

  • Cornices

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Likely - Very Likely
    Tamaño
    2–3
    Cornices are collapsing with the warmer temperatures triggering slabs on underlying slopes.

  • Loose Wet

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Likely
    Tamaño
    1–3
    Loose wet slides are being triggerred with the warming temps or rain. Some loose wet slides may wake up a wet slab failing at ground underlying slopes.

  • Deep Persistent Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Unlikely - Possible
    Tamaño

    We are not entirely free from this layer yet. It is still down there and more suspect in thin areas, cold areas that haven't seen a warming cycle and large terrain that hasn't avalanched yet.

Confidence

Moderate - Freezing levels are uncertain on Friday

Weather Forecast

Avalanche Summary

A few loose wet avalanches up to sz 1 with the warmer temps. Otherwise no new observations or reported avalanches.

Snowpack Summary

Limited observations these days as the season starts to wind down. Temps on Thursday climbed to 12C at 2200m with lots of cloud cover. Light rain was falling starting in the afternoon and lower elevation terrain was going isothermal. Freezing levels climbed to 2500m so expect to encounter moist snow to this elevation. Above this elevation, dry snow can still be found on N aspects but dont expect long runs of powder. As you approach treeline, the MFC of spring returns and skiing gets a bit more challenging. South aspects are starting to "Corn" up but its not full on spring corn season just yet.
