Lo esencial

Not a lot of change with the snow despite the warmer weather. Loose surface snow, sluffing and variable wind slab in the alpine are the on the radar as concerns.

Problemas de aludes

  • Wind Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Unlikely - Possible
    Tamaño
    1–2
    Wind slab conditions are highly variable, including hard slabs, soft slabs and buried slabs. Watch for human-triggerable slabs in steep terrain on all aspects, and take the time to evaluate localized conditions.

  • Loose Dry

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible - Likely
    Tamaño
    1–2
    Be cautious in steeper terrain. Increased solar input and warm temperatures will lead to more frequent sluffing on solar aspects. Ice climbers need to be aware of overhead terrain and how it impacts their route.

Weather Forecast

The warming trend will continue through tonight and into tomorrow. Overnight lows will be -2 at 2200m. Tomorrow it will hit 0° at 1600m with a mix of sun and cloud. No snow and only light winds are expected.

Avalanche Summary

A few loose dry avalanches may have come down in the last 24 hours, but it is hard to say exactly how old these are. Regardless, most of them were small and in steep alpine terrain. Some minor pinwheeling was noted today.

Snowpack Summary

Surface hoar growth continues with the cold, clear and calm weather. It is not clear yet how widespread this latest surface hoar is. The snowpack has lost a lot of its strength through facetting, especially near the surface. So far none of the crusts or storm interface from last week have woken up, and appear to be hanging in there for the time being. Having said that, it does feel like the the deeper layers could wake up with even a slight change in conditions.
