Lo esencial

Warm temperatures, little overnight recovery, and bursts of solar power starting tomorrow will make loose wet avalanches likely where snow still exists on solar aspects.

Problemas de aludes

  • Wind Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible
    Tamaño
    1–3
    Warm temperatures will be helping bond soft slabs and windslabs in lee features in the alpine and at treeline in shaded lee features.

  • Loose Wet

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible - Likely
    Tamaño
    1–2
    Expect the sun to have a lot of power when it makes an appearance. Rising freezing levels make a solar trigger much more likely.

  • Deep Persistent Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Unlikely - Possible
    Tamaño
    2–3
    Large cornices or surface avalanches are the likely trigger.

Weather Forecast

Temperatures and freezing levels are expected to dramatically rise tomorrow afternoon and with expected cloud cover, we will see little recovery overnight. Light precip can also be expected as waves of convective cloud pass through. This intermittent cloud will bring strong solar effects whenever the skies clear.

Snowpack Summary

Warm temperatures will continue to bond the new snow to the old snow surfaces in areas that are sheltered from direct solar influence. Rising daytime freezing levels are combining with PM solar to weaken the soft slab on steeper solar slopes.
