Dangerous avalanche conditions. Careful snowpack evaluation, cautious route-finding, and conservative decision-making are essential.
Skiers: Stick to low angle, sheltered slopes while the snowpack is going through significant loading.
Climbers: Avoid all overhead hazard, this is not the time to push exposure.

There have been numerous natural windslabs observed throughout the park up to size 2.5 over the past few days. Many bed surfaces have been reloaded with new snow. Avalanche control at Parker's ridge produced slabs up to size 3 with good propagation at ridge top.

Potential for triggering large destructive slabs remains a concern.

Up to 50 cm of snow fell since this past weekend. Strong winds from the west and north west have scoured much of the alpine and tree line and loaded lee features. The mid and lower pack consists primarily of facets. A small crust is located 30cm from the bottom. Snowpack ranges from 60 to 120cm at treeline in the Icefields. The Bald Hills area has received less storm snow; the average height is ~60cm.

• Expect slab conditions to change drastically as you move into wind-exposed terrain.
• Keep your guard up at all elevations. Wind slab formation has been extensive and could extend into openings below treeline.
