Snowpack Summary
Supportive melt-freeze crust on all aspects and elevations; northerly aspects above treeline may still hold dry snow. The mid-pack is thick and supportive. Persistent weakness near the bottom of the snowpack will remain a concern in shallow areas and northerly alpine aspects.
Avalanche Summary
Freezing levels continue to rise this week - expect increasing avalanche activity in the afternoon.
Confidence
Problems
Loose Wet
Subject to type of load, time of day, aspect and elevation.
Possible at all elevations and aspects.
- Use extra caution on solar slopes or if the snow is moist or wet.
- If triggered the loose wet sluffs may step down to deeper layers resulting in large avalanches.
Aspects: All aspects.
Elevations: All elevations.
Likelihood
Expected Size
Wet Slabs
Subject to type of load, time of day, aspect and elevation. Anticipate large slabs in connected features. ANY slide is likely to be large and will entrain the remaining winter snowpack
- Daytime warming will weaken surface layers, plan your day around being back to the trailhead early.
Aspects: South East, South, South West, West, North West.
Elevations: All elevations.
Likelihood
Expected Size
Cornices
Unpredictable and likely to trigger deeper instabilities on the slopes below.
- Pay attention to overhead hazards like cornices which could easily trigger deep slabs.
- Cornices become weak with daytime heating, so travel early on exposed slopes.
Aspects: North, North East, East, South East, North West.
Elevations: Alpine.
