In sintesi

Travel is generally safer in deeper snowpack terrain features while avoiding thin and thick-to-thin areas. Carefully assess and monitor the amount of snow your party is traveling on.

Problemi valanghivi

  • Persistent Slabs

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

    The Feb 3 crust/facet interface is down 50-100 cm. Triggering avalanches is possible in thin snowpack areas.

  • Deep Persistent Slabs

    Thin and thick-to-thin features as well as polar aspects of the alpine are higher likelyhood areas for triggering this avalanche problem.

Avalanche Summary

No recent avalanches to report.

48h ago there was a size 3, remote-triggered avalanche in the Lake Louise backcountry.

Snowpack Summary

Northerly aspect of the alpine still hold dry snow. While there is a sun crust to ridge top on solar aspects. The crust also exists on specific terrain features treeline, and below on polar aspects.

The March 20 temperature crust extends to 2100 m on all aspects and to ridge top on solar aspects.

The Feb 3rd layer is down ~ 50 -100 cm and the weak basal facets persist in thin snowpack areas.

Total snowpack depths range from 90-170 cm at treeline.

Weather Summary

Monday: Light West/NW winds, freezing levels rising to 1500m with a mix of sun and cloud. -4 C is the forecast high at 2000m.

Tuesday: Up to 2000m freezing levels, winds moderate out of the west and the potential for snowfall/convective activity in the afternoon, less than 5 cm forecast.
