Potential for a significant solar triggered cycle on an already active snowpack for the rest of the week.
Start early, seek out dry slopes, and finish early!
Continued wind slab development is expected with overnight snowfall and moderate SW winds.
Wind slabs in the alpine and exposed treeline features have the potential for wide propagations across connected features.
Afternoon sun is packing a punch on lower elevation, SW through W slopes. Ice climbers: be extremely cautious. Overhead hazards can catch sun early.
Caution in thin facetted snowpack areas where triggering is more likely. This is a low probability but high consequence problem.
Overnight: Mainly cloudy. Alpine temperature: Low -12 °C. Ridge wind sw: 10 km/h.
Wednesday: Mainly cloudy. Alpine temperature: High -6 °C. Ridge wind sw: 10 km/h. Freezing level: 1400 m
Thursday: Cloudy with sunny periods. Alpine temperature: Low -10 °C, High -4 °C. Ridge wind sw: 10 km/h. Freezing level: 1800m
Continued widespread wind effect with some light precip. transported through open areas at all elevations. Windward aspects have been heavily stripped of snow, creating hard windslabs in all lee features. Highly variable snowpack across the region, with shallow areas failing at the faceted base, while deeper regions have a strong mid-pack bridge.
Wind slabs up to size 2-3 were observed again today in the Sunwapta Zone on E and SW aspects.
