Lo esencial

Only a light freeze is forecasted for Monday night, followed by a very warm day on Tuesday. Pay attention to how quickly the snow is warming up.

Problemas de aludes

  • Cornices

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible
    Tamaño
    1–3
    The forecasted warm/hot temperatures midweek will create a situation where cornices are more unstable. Cornices, combined with the hot temperatures, have the possibility to triggering the deep basal layers.

  • Loose Wet

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Likely
    Tamaño
    1–3
    Expect solar triggered avalanche activity on steep solar aspects in the afternoon. It is possible that wet slides could trigger the basal facet layers if they have enough mass. Start early and be off steep solar aspects by midday.

Weather Forecast

Tuesday will be mainly sunny with  light winds and freezing levels rising up to 2900 m. Wednesday will be slightly cooler with the potential for some scattered showers.

Snowpack Summary

Supportive crust on solar aspects in morning which are deteriorating by early afternoon. High elevation east and north still have dry snow. Mid pack is well settled with no significant shears. The basal facets remain the main weakness in the snowpack, but we expect only large loads or a dramatic rise in temperatures to cause failures on this layer.

Avalanche Summary

Loose snow avalanches up to size 1.5 on solar aspects in afternoon.
