Avalanche Summary

Numerous loose dry avalanches (size 1.5) failed naturally (some with cornice fall as the trigger) and with skier traffic in steep terrain on Friday and Saturday. In the south-east of the region, a couple of size 2 slabs were triggered by explosives.

Snowpack Summary

10-30 cm of snow which fell on Friday added to recent snowfall above old surfaces including loose dry snow, old wind slabs and sun crusts. This recent snow has been shifted onto lee slopes by strong SW to NW winds. New storm slabs, cornices and wind slabs are likely. Mid and lower snowpack layers are generally well settled and stable.
