Avalanche Forecast
Regions: Brazeau, Churchill, Cirrus-Wilson, Fryatt, Icefields, Jasper, Maligne, Marmot, Miette Lake, Pyramid.
Windslabs are the name of the game right now. Avoid alpine and treeline features that have been affected by wind or have been loaded.

Terrain and Travel Advice
- Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
- Avoid exposure to overhead avalanche terrain; avalanches may run surprisingly far.
Avalanche Problems
Wind Slabs
Recent strong to extreme winds have built windslabs in the alpine and treeline. The variable direction of winds have built windslabs on atypical slopes. Most natural avalanches have occurred near treeline. Avalanches triggered in windslabs may step down to the Deep Persistent Layer.
Aspects: All aspects.
Elevations: Alpine, Treeline.
Likelihood: Possible
Expected Size: 1 - 2.5
Deep Persistent Slabs
A variety of crusts with facets above and below exist at the bottom of the snowpack. These layers are going to be with us for a long time and pose a low probability, high consequence situation if triggered.
Aspects: All aspects.
Elevations: Alpine, Treeline.
Likelihood: Unlikely - Possible
Expected Size: 1.5 - 3
