Lo esencial

Start your day early and watch the crust closely.

As it breaks down, reduce your exposure to avalanche terrain.

Problemas de aludes

  • Cornices

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Unlikely - Possible
    Tamaño
    1.5–2.5

    Large cornices hang over many ridges and are more likely to collapse during warm, sunny weather.

  • Loose Wet

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible - Likely
    Tamaño
    1–3

    Wet loose avalanches will become more likely as the sun and warmth affect the snowpack. Start early, and avoid the hottest part of the day.

Terrain and Travel Advice

  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
  • Avoid steep, sun-exposed slopes when the air temperature is warm or when solar radiation is strong.
  • Avalanche danger will increase as the surface crust breaks down.

Confidence

Moderate

Avalanche Summary

Wet loose avalanches have been occurring on steep slopes facing the sun. Mostly small, but some large avalanches (size 2 to 3).

Snowpack Summary

A thin surface crust is expected to cover up to 25 cm of recent snow at upper elevations. This snow overlies a robust crust everywhere except northerly aspects in the alpine.

Most terrain has undergone strong melt-freeze cycles, but the snowpack remains slightly more complex on north-facing alpine slopes, where buried weak layers may still be present.
