Insufficient observations exist to reliably rate the avalanche danger. Expect shallow snow cover with thinly buried rocks and trees just beneath the surface. Avalanche danger often concentrates in gullies and other deposition areas, where windslabs may bond poorly to a weak underlying base. Deeper snow usually exists at higher elevations.
These have caught scramblers in places like the West bowl on Cavell, & alpine climbers on routes like Side Street. Hikers: avalanche hazard may exist on the Skyline trail. Ice climbers: consider overhead slopes, and wind-loaded slopes on approaches.
Sun, or fluctuating freezing levels can rapidly transform cold powder snow into moist mush. When this happens, natural avalanches will run in steep solar terrain. Avoid climbs with overhead hazard, or in gullies, when sun or soaring temps threaten.
Recent snow and wind increase frequency of loose dry sluffs in steep, shaded terrain. With early season ice pro sometimes scarce, and tenuous pick placements, climbers should consider the risks of a sluff-induced fall if tapping up early season ice.
Deep persistent slabs are best managed by:
Cornices are best managed by:
Expect the current alternation of cold fronts and sunny spells to continue. Watch out if fluctuating freezing levels, or rain, leave crusts - these may act as sliding layers down the road.

Currently, Alpine areas above threshold for avalanches are widespread West of the 93N, but only isolated to the East. Many open crevasses are hidden by thin bridges of wind-blown snow. Roping up, diligent probing, and glacier reading experience are critical for glacier travel.
Danger is highest after new snowfall, rain, or wind transport - expect increased avalanche activity during, & for 24 hrs after such events. Use extra caution where slabs lie over alpine ice -this surprised climbers on Mt Athabasca last year. Tis' the season: do your own avalanche forecasting; carry a transceiver, shovel & probe; and practice.
