Lo esencial

The snowpack is isothermal at lower elevations. Hazard levels will be highly dependent on the quality of the overnight freeze and the extent of daytime heating and solar radiation. Keep an eye on localized conditions.

Problemas de aludes

  • Wind Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible
    Tamaño
    1–4
    Recently formed thin wind slabs have added to previously formed wind slabs in alpine areas. Be curious as you enter the alpine and carefully observe the bond between these wind slabs and the previous surfaces. Conditions are highly variable.

  • Loose Wet

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Very Likely
    Tamaño
    1–3
    A weak freeze is likely overnight Saturday, but expect the snowpack to warm up quickly Sunday as the snowpack is currently isothermal at lower elevations. Any sunny periods will also warm the snowpack rapidly.

  • Deep Persistent Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Unlikely - Possible
    Tamaño
    2–5
    The basal weak layers have been dormant of late, but warm temperatures and recent loading could awaken this persistent weak layer, especially in steep and shallow snowpack areas.

Confidence

Good

Weather Forecast

Mainly cloudy on Sunday with no precipitation expected. Alpine temperature should reach -2 °C, with ridge wind out of the west: at50 km/h gusting to 90 km/h. Freezing level are forecast to reach 2100 metres.

Avalanche Summary

Several loose wet up to size 2.0 observed on all aspects below 2400m. Extensive snowballing at treeline and below.

Snowpack Summary

5 to 15cm of heavy wet snow fell at treeline in the past 36hrs, with rain below 2200m. Snow conditions are isothermal below treeline and boot penetration is to ground. Thin storm slabs are present in the alpine on all aspects.
