Sunshine will continue with little change to skiing conditions. Look for preserved powder in sheltered terrain.
Don’t get complacent with the deep persistent slab - it remains a low-probability, high-consequence problem. Be cautious in areas with thinner snowpacks or where the snowpack transitions from thick to thin.
This problem is low probability - high consequence! Be cautious where the snowpack transitions from thick areas to thin areas. A recent size 3 avalanche has been observed on this layer. This problem encompasses multiple weak layers of facets, crusts, and basal facets from November and December.
Lingering windslabs from earlier in the week may still exist in isolated alpine features.
A size 3 deep persistent slab was triggered in terrain adjacent to the ski hill on Friday. Although natural avalanche activity has tapered, the deep persistent slab remains a low-probability, high-consequence problem.
Maligne Road Patrol on Saturday observed several solar triggered avalanches up to size 1.5
Strong winds earlier this week created firm, wind-affected surfaces in exposed terrain at all elevations, while softer snow remains in sheltered areas. Sun-exposed slopes host variable crusts, especially on steep aspects.
The snowpack is deeper in the Icefields and more shallow & weak in the Maligne area.
The deep persistent slab remains a concern, particularly in thin areas or with large triggers like cornice falls.
