Lo esencial

The sun is packing a lot more punch now. It's a good time of year to start and finish early before things get too warm.

Problemas de aludes

  • Persistent Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible
    Tamaño
    1.5–3

    A persistent weak layer of facets is down 80–120 cm and may still be triggerable by humans in shallow areas, or by large loads like collapsing cornices.

  • Loose Wet

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible - Likely
    Tamaño
    1–2

    Watch for this problem to develop during the day as the intensity of the sun increases and the temperatures warm.

Terrain and Travel Advice

  • A moist or wet snow surface, pinwheeling, and natural avalanches are all indicators of a weakening snowpack.

Confidence

Moderate

  • We are uncertain about how the timing or intensity of solar radiation will affect the snowpack.

Avalanche Summary

No new avalanches have been observed in the last couple days.

Snowpack Summary

Up to 10cm of new snow has been redistributed by previous SW winds, and overlies a sun crust on solar aspects. A thicker melt-freeze crust is found down 20–40 cm at tree line and below. The Jan 24 persistent weak layer is 80–120 cm deep, and mainly a lingering concern in the alpine.
