Snowpack Summary
MIN reports from the weekend describe extensive wind affect at higher elevations, while softer snow can be found in sheltered terrain. Recent wind from the southwest and north has left hard wind slabs near ridgetops and lee terrain. In isolated areas, these small slabs are likely sitting on a mix of sugary faceted snow or feathery surface hoar crystals, which could make them reactive to human triggering. Warm alpine temperatures and sunny weather on Monday could also weaken these slabs. Snowpack depths are 50-100 cm in alpine areas around Smithers, with depths diminishing rapidly below 1500 m.
Problems
Wind Slabs
Hard wind slabs exist in alpine terrain and may become more reactive to human triggering on Monday due to warm alpine temperatures.
Aspects: North East, East, South East, South, South West.
