Northerly winds are transporting snow around in the north part of the Jasper region. This combined with the new snow is likely creating wind slabs on non-typical south facing aspects.

Terrain and Travel Advice
- Loose avalanches may start small but they can grow and push you into dangerous terrain.
- Be carefull around freshly wind loaded features.
Problems
Wind Slabs
The winds have switch to the north again. Watch for isolated reverse loaded wind slabs on south facing aspects.
Aspects: South East, South, South West.
Elevations: Alpine.
Likelihood
Expected Size
Loose Dry
A handful of loose dry avalanches have occurred recently with one scrubbing to ground. They are currently limited to specific terrain such as very steep alpine rocky terrain yet enough of a concern if a person is standing below it or gets swept away.
Aspects: All aspects.
Elevations: Alpine.
Likelihood
Expected Size
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.
