In sintesi

Still good skiing on sheltered northerly aspects. Start your trip early and plan to be back at the trailhead before the heat and solar radiation becomes intense.

Problemi valanghivi

  • Wind Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible - Likely
    Dimensione
    1–2

    Wind slab were observed on all aspects in the alpine. These may be more sensitive to triggering where the underlying crust is prominent.

  • Persistent Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible
    Dimensione
    2–3.5

    Watch for sheltered northern areas where this layer may still exist.

  • Loose Wet

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Likely
    Dimensione
    1–2

    With the sunny skies and intense solar radiation, loose wet avalanches are expected, especially in steep rocky terrain.

Confidence

Moderate

Avalanche Summary

No field team today. No avalanches reported.

Snowpack Summary

New wind slabs were evident in the alpine on all aspects. While these slabs are not deep, they could be sensitive to triggering where the underlying surface is a smooth crust. Otherwise, expect a melt-freeze surface layer on all solar aspects as well as all aspects at lower elevations. Higher elevation northerly aspects still hold dry snow. Cornices are starting to sag in the mid-April heat, and some recent collapses have been observed.

Weather Summary

Wednesday will be cloudy with sunny periods and isolated flurries. Winds will pick up and be in the 25-45km/h from the Northeast. Day time high of -6. Freezing levels will remain below valley bottom (1600m)

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Even brief periods of direct sun could produce natural avalanches.
  • Avoid shallow snowpack areas, rocky outcrops, and steep terrain where triggering is most likely.
  • Wind slabs are isolated, but may remain reactive.
  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
  • Avoid steep, sun-exposed slopes when the air temperature is warm or when solar radiation is strong.
