Avalanche Summary
Storm and wind slab avalanches were likely triggerable on Saturday and into the night at high elevations. The snow could still be triggered on Sunday for areas that received sufficient snowfall.
Snowpack Summary
You may find around 10 to 20 cm of snow from Saturday's storm above 1600 m. The snow fell with strong southeast wind, so wind slabs may be found at high elevations on lee terrain features. The snow overlies a hard melt-freeze crust everywhere except for wind-affected snow on north aspects above 1600 m, so it could take a few days to bond to underlying surfaces. If sunny skies prevail on Sunday, the snow may moisten on sun-exposed slopes. Below around 1600 m, the snow is likely wet or has frozen into a hard melt-freeze crust.
Cornices are large and looming along ridgelines. Their release is unpredictable, requiring a large berth if you're travelling above or below them.
