Watch for signs of previous reverse wind loading and dry loose avalanches. Just because it is cold doesn't mean that avalanches can't happen.




Avalanche Summary

Loose dry avalanches to size one from steep rocky terrain were observed across Jasper on Thursday. No field patrol Friday or Saturday.

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.

Terrain and Travel Advice

  • Recent wind has varied in direction so watch for wind slabs on all aspects.
  • Loose avalanches may start small but they can grow and push you into dangerous terrain.


Deep Persistent Slabs

An icon showing 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.

Aspects: All aspects.

Elevations: Alpine.


Unlikely - Possible

Expected Size

1.5 - 2.5

Wind Slabs

An icon showing Wind Slabs

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

Aspects: South East, South, South West, West.

Elevations: Alpine, Treeline.



Expected Size

1 - 2

Loose Dry

An icon showing Loose Dry

The cold temperatures and the clear skies will trigger loose dry avalanches from steep rocky terrain. These avalanches by themselves will be of low risk unless you are in a terrain trap or above a cliff.

Aspects: All aspects.

Elevations: Alpine.


Possible - Likely

Expected Size

1 - 2
