Avalanche Summary
On Saturday, naturally triggered (some by cornice fall) slabs to size 2 were observed on steep slopes. 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. In the south-east of the region, a size 2 slab was 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 (up to 50 cm total) 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.
Problems
Storm Slabs
Recent snow and wind has created touchy slabs, particularly in the lee of terrain breaks such as ridges and ribs.
Avoid freshly wind loaded features.>Give cornices a wide berth when travelling on or below ridges.>Be cautious of sluffing in steep terrain.>
