    This problem was most active in the Maligne and surrounding Jasper area where the average snow pack is shallow but is proving much less active in the Icefields area.

Weather Forecast

Mainly cloudy with isolated flurries for the Maligne and Icefields areas. 3 to 4cms Sunday evening with trace amounts expected through the beginning of the week. Valley bottom freezing levels and alpine temperatures to -5 °C. Gusty westerly winds over the day Monday.

Snowpack Summary

Maligne/Jasper: Variable snow depth above tree-line, relative to exposure. Average HS 70cm. Surface wind slabs and persistent slab down 40-90cm. Icefields: Variable snow depth above tree-line, relative to exposure. Average HS 120cm. Widespread wind slabs overlaying supportive mid pack and weak base.

Avalanche Summary

No new avalanches observed or reported

Confidence
