Points saillants

The hazard will increase in the afternoon as the day warms up. This is the time of year to start your trip early.

Problèmes avalancheux

  • Cornices

    • Alpin
    • Limite forestière
    • Sous la limite forestière
    Probabilité
    Possible - Likely
    Taille
    1.5–3

    After several days of warm temperatures cornices are weak and susceptible to failure. Cornices may trigger larger avalanches on slopes below.

  • Loose Wet

    • Alpin
    • Limite forestière
    • Sous la limite forestière
    Probabilité
    Possible - Likely
    Taille
    1–2

    Warm daytime temperatures and high freezing levels will increase the possibility of a loose wet problem at treeline and below. Even short period of solar inputs may cause a rapid deterioration of the snowpack.

Weather Forecast

Minimal re-freeze on Sunday night and another warm day on Monday with freezing levels between 2100-2300 m. Light flurries forecasted with minimal accumulation.

Snowpack Summary

Surface melt freeze crusts exist on all aspects up to approx. 2300m. On high elevation north aspects dry snow can be found. The mid-pack is well settled but has several persistent layers consisting of crusts and/or facets. These are currently unreactive to skier triggering but may wake up as spring heat penetrates the snowpack.

Avalanche Summary

A ski touring party reported a cornice triggered size three slab on the north side of Cathedral Peak on Sunday.
