Avalanche Forecast
Regions: Glacier.
Don't let the variability in storm slab composition catch you off guard!
Carefully assess each feature as you travel today.
Weather Forecast
Westerly flow continues, bringing another series of frontal systems to the region.
Today: flurries accumulating to 6cm. Freezing levels rising to 1100m. Wind SW-40 gusting to 70 km/h
Tonight: mainly cloudy with isolated flurries. Freezing level 900m. Wind SW-35 km/h
Tomorrow: flurries accumulating to 5cm. Freezing level 1200m. Wind SW-25 km/h
Snowpack Summary
Moderate to strong southerly winds have redistributed the 30-60cm that now overlays the Nov 5th crust. At treeline, the meter plus snowpack consists of a series of crusts with weaker snow surrounding the crusts. The strong Nov 5th crust reaches as high as 2500m, and potentially higher on steep solar aspects.
Avalanche Summary
Notably, a skier accidental with a full burial occurred yesterday up Connaught Creek, where the storm slab was initiated on the November 5th crust. Moderate to strong S'ly winds have also initiated numerous natural avalanches from alpine features on all aspects, large enough to bury, injury or kill a rider.
Confidence
Intensity of incoming weather systems is uncertain
Avalanche Problems
Storm Slabs
Watch for storm slabs gaining cohesion over the Nov 5 crust at and above treeline, especially where wind effect may amplify their sensitivity to human triggering.
