Avenir Light is a clean and stylish font favored by designers. It's easy on the eyes and a great go-to font for titles, paragraphs & more.
Date: 2026-04-26 | Time: 2341
Location: Whistler_Blackcomb
Avalanche Observations and Summary:
No Significant Avalanche Observations
Snowpack Description:
The surface snow includes a thick, often breakable melt-freeze crust with moist to wet snow in upper 50 cm to 1 m, especially on lower or solar aspects. Midpack layers consist mostly of firm, dry snow with interspersed hard ice lenses. Persistent weak layers include a notable old faceted layer with an associated ice lens near 1.8–2 m depth (February 7), requiring ongoing monitoring. Basal snow remains cold and hard above glacier ice or ground, with temperatures dropping to -3°C near the bottom. Operators managed challenging, variable terrain with slopes up to 40° featuring corn on solar aspects and frozen conditions. The dominant strategic mindset was Spring Diurnal, focusing on avoiding avalanche terrain during afternoon thaw phases and monitoring freeze-thaw cycles.
Previous Avalanche Hazard Assessment and Stability:
Alpine: Low
TL: Low
BTL: Low
Signs of Instability:
Cornice fall observed on steep upper northern aspects of Disease Ridge.
Current Avalanche Problems:
No new avalanches were observed at most locations, except for a small cornice fall avalanche on steep upper northern aspects of Disease Ridge. This narrow avalanche traveled a few hundred meters.
Previous Reports:
No data provided
Key Actions and Safety Considerations:
• Avoid steep northern aspects near Disease Ridge.
• Monitor melt–freeze cycles and afternoon thaw phases.
• Use conservative terrain choices on slopes up to 40°.
• Stay alert for isolated cornice fall triggers.
Closing Summary:
Overall conditions remain stable with minimal avalanche activity aside from an isolated cornice fall event. Prioritize early morning or refrozen conditions for optimum snow quality and exercise caution on steep slopes.
