Points saillants

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 size they will occur.

Problèmes avalancheux

  • Cornices

    • Alpin
    • Limite forestière
    • Sous la limite forestière
    Probabilité
    Possible - Likely
    Taille
    2–3

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

  • Loose Wet

    • Alpin
    • Limite forestière
    • Sous la limite forestière
    Probabilité
    Likely
    Taille
    1–1.5

    Wet loose avalanches are likely with high freezing levels and sun.

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

Sunday Night

Clear skies. 20 km/h south ridgetop wind. Treeline temperature 5 °C. Freezing level 2600 m.

Monday

Mostly sunny. 30 km/h southwest ridgetop wind. Treeline temperature 6 °C. Freezing level 2700 m.

Tuesday

Mostly cloudy. 3 to 5 cm of snow. 40 km/h west ridgetop wind. Treeline temperature -3 °C. Freezing level 1600 m.

Wednesday

Mostly sunny. 2 to 3 cm of snow. 30 km/h northwest ridgetop wind. Treeline temperature -4 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • A moist or wet snow surface, pinwheeling, and natural avalanches are all indicators of a weakening snowpack.
  • Avoid travelling on slopes below cornices.
