Lo esencial

Be alert to conditions that change with daytime warming. Danger ratings may exceed posted levels when solar radiation is strong.

Problemas de aludes

  • Cornices

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible
    Tamaño
    1–6
    Cornices weaken with daytime warming and become more likely to fail.

  • Loose Wet

    • Alta montaña
    • Límite del bosque

Weather Forecast

Clear skies are expected on Sunday with increased cloud on Monday and a chance of very light precipitation on Tuesday. Winds will be mostly light from the northwest switching to southwest on Tuesday. Freezing levels may reach 2200m on Sunday, 2500m on Monday and then 2100m on Tuesday.

Avalanche Summary

Natural wet-loose avalanches up to Size 2.5 continue to be reported from throughout the region on solar aspects. Isolated cornice releases up to 2.0 have also been reported.

Snowpack Summary

Clear, warm days and cold nights have brought spring's daily melt freeze cycle to the surface snow on sunny aspects into the alpine and all aspects at lower elevations (below 1800m). On high shaded terrain surface hoar is growing, and warm temperatures have promoted settlement within the upper snowpack. Cornices are huge!The weak layer of buried surface hoar from March 10th is buried more than 100cm in most places, and is now difficult to trigger. Although unlikely to trigger, this deep persistent weakness has the potential for very large avalanches particularly with very heavy triggers such as cornice falls or ice fall.
