    This is an early winter avalanche problem that exists in isolated pockets where the snow has drifted into small 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 is forecast for Saturday and Sunday with cloudy skies and -5 to -12 degrees Celsius. Snow fall amounts will increase slightly on Monday ranging from 10-20cm with slightly warmer temperatures. Forecasted snowfall amounts are not yet clear though and we expect to be on the lower end, which will not change the current danger rating. 

Snowpack Summary

Field data is limited and its early season conditions. 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. Rocks and timber is marginally covered.

Avalanche Summary

Jasper to Sunwapta station patrol observed nothing new. It is not uncommon at this time of year for climbers to trigger small avalanches from gully features. Even small rides over rocky terrain or cliffs can have serious consequences.
