    Reverse loading from NE winds have likely created wind slab on non-typical SW aspects in the alpine.

  • Deep Persistent Slabs

    You must keep this basal layer on your radar as triggering is possible in isolated features, such as steep rocky terrain where you find yourself standing on the surface and not wallowing in facets, that's the problem slab.

Avalanche Summary

Loose dry avalanches to size one from steep rocky terrain were observed across Jasper on Thursday.

Snowpack Summary

Cold temperatures continue to weaken the snowpack. There is a possibility of reverse wind loading from previous NE winds in the alpine. Cold temperatures can cause a wind slab problem to persist longer than normal. Old persistent weak layers are present in the snowpack but continue to facet and are unreactive in snow pit tests.
