    This is an early winter condition that exists in isolated pockets where the snow has drifted into pockets of wind slabs and the slope is steep enough to slide. Mainly a concern for ice climbers in steep gullies or walking above cliffs.

Weather Forecast

Light flurries, clouds, -6 to -9 for Sunday. Monday may bring in a pulse of snow, 10-20cm, South to Southwest light to moderate winds, 1800 freezing level, and -3 to -6 degrees Celsius. Models are not agreeing on the snow amounts thus expect it to vary locally.

Snowpack Summary

Field data is limited. Below 1700m there is no significant snow. 2000m and above 30cm plus can be expected. Snow distribution varies with aspect, elevation, and wind exposure. Treeline and alpine gully features as well as some alpine slopes will be wind loaded. Its early season snowpack and ground features are marginally covered.

Avalanche Summary

No patrol Saturday. Friday Jasper to Sunwapta station patrol observed nothing new. Climbers should still remain vigilant as even triggering a small avalanche in a gully feature or above cliffs can have severe consequences.

Confidence

Forecast snowfall amounts are uncertain on Monday
