    No new natural activity on this layer has been noted for a few days yet potential still exists on steep unsupported wind loaded slopes.

  • Persistent Slabs

    A persistent facetted weakness can be found around a mid-pack crust. There is low likelihood of natural avalanches occurring on this layer but we are watching as each small system deposits more snow load.

Weather Forecast

A warm and a cold air mass are converging over Jasper. Up to 10 cm of snow is expected but local accumulations may be twice that. Temperatures will range from -15 to the freezing mark , so be prepared for a variety of weather this weekend.

Snowpack Summary

A couple cms of new snow fell today with minimal wind effect. Wind slabs created after last week's storm continue to be our biggest concern in the snowpack, particularly at ridge tops and cross loaded features. 

Avalanche Summary

No new avalanches were observed in the past 48 hours.

Confidence

Intensity of incoming weather systems is uncertain
