In sintesi

There is zero skier support below treeline. Early season hazards lurk just under the snow. Watch for increased potential of natural activity on Monday and Tuesday if temperatures increase particularly on South aspects.

    A 4cm thick rain-crust exists 40cm down at treeline on East aspect. Whether its on all aspects and at higher elevations is low confidence. Moderate winds continue to load slopes.

Weather Forecast

Clouds, flurries, and seasonal temperatures will continue in the Icefields. Warmer temperatures may occur Monday with -2 degrees Celsius at 3000m.

Snowpack Summary

At Hilda ridge, snowpack ranges from 5-100cm with a 4cm raincrust down 40cm at treeline and suspect it existing at higher elevations. A 15cm windslab exists in open areas treeline and above. Moderate wind transport continues. Height of snow is 45cm at the parkers ridge summer trail weather plot.

Avalanche Summary

Three size 2's was noted off Kitchener ridge today on East aspect. Likely 48hours or older. A few size 1 solar releases observed on South aspects. 

Confidence
