In sintesi

Keep an eye on changing conditions and dial back your objectives.

We are confident that warming and solar will trigger avalanches, but we are uncertain in the that will occur.

Problemi valanghivi

  • Cornices

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible - Likely
    Dimensione
    2–3

    Rising freezing level and solar input will increase the likelihood of cornices failing naturally.

  • Wet Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible - Likely
    Dimensione
    1.5–2.5

    Wet slab avalanches are possible as the upper snowpack becomes wet from solar input and rising freezing level.

    Wet loose avalanches are also likely.

Confidence

Moderate

  • We are confident that there are weak cornices, but uncertain about how likely they are to trigger.
  • We are confident the likelihood of avalanches will increase with the forecast weather.
  • We are uncertain due to rapidly changing freezing levels.

Avalanche Summary

Over the past 4 days several small wet and dry loose avalanches in steep or extreme terrain were observed.

Observations are limited in this region this time of year.

Snowpack Summary

Surface conditions are highly variable:

·        In exposed alpine and treeline terrain recent variable wind has scoured ridge tops and formed small wind slabs in lee features.

·        Sheltered treeline features may hold dry snow.

·         Below treeline A firm crust is on or just below the surface on all aspects.

·        A crust exists on or near the surface on sun exposed slopes. This crust will break down with solar input and rising freezing level.

The melt freeze crust from the atmospheric river event is buried up to 50 cm. The snowpack below this crust is well consolidated.

Weather Summary

Saturday Night
Mostly clear skies. 10 km/h southwest ridgetop wind. Treeline temperature -1 °C. Freezing level 1800 m.

Sunday
Mostly sunny. 10 km/h southwest ridgetop wind. Treeline temperature 4°C. Freezing level 2700m.

Monday
Mix of sun and clouds. 1 to 2 mm of rain at treeline, snow in the alpine. 30 km/h southwest ridgetop wind. Treeline temperature 4°C. Freezing level 2700 m.

Tuesday
Mostly cloudy. 3 to 5 cm of snow. 40 km/h west ridgetop wind. Treeline temperature -4 °C. Freezing level 1500 m.

Terrain and Travel Advice

  • Back off slopes as the surface becomes moist or wet with rising temperatures.
  • A moist or wet snow surface, pinwheeling, and natural avalanches are all indicators of a weakening snowpack.
  • Avoid travelling on slopes below cornices.
  • Be careful as you transition into wind-affected terrain.
