Lo esencial

Spring Conditions. If the sun comes out, the strong solar radiation will heat up the snowpack rapidly and avalanche danger will increase. New wind slabs may not be well bonded to the old surface crust.

Problemas de aludes

  • Wind Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible
    Tamaño
    1–2
    Thin new wind slabs may be easy to trigger when they are exposed to strong solar radiation. Wind slabs may not be well bonded to the old surface crust.

  • Cornices

    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible
    Tamaño
    1–4
    If the sun comes out, it wont take long for solar aspects to heat up and result in natural cornice falls.

  • Loose Wet

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible - Likely
    Tamaño
    1–2
    Loose wet avalanche activity is expected to increase with exposure to strong solar radiation and climbing freezing levels.

Weather Forecast

Mostly cloudy overnight with light to moderate northerly winds developing and freezing levels down close to 1000 metres by morning. Cloudy on Thursday with periods of light snow and freezing levels climbing to 2000 metres. Overcast with convective flurries on Friday combined with light southerly winds. Freezing levels starting out near 1500 metres and rising up to at least 2000 metres. Not much of a re-freeze expected for Saturday morning, mostly sunny with freezing levels climbing to at least 2500 metres.

Avalanche Summary

No new avalanches reported.

Snowpack Summary

The snow surface is currently going through a typical spring melt-freeze cycle on all aspects and at all elevations, except possibly high true-north slopes which could be holding onto cold snow. Forecast new snow and wind are expected to develop new windslabs in the alpine and at treeline. Higher elevations may feel more like winter for the next day or two, and new wind slabs may not bond well to the old hard re-frozen surface.
