The new snow falling over the weekend came with strong east and northeast wind, so expect to find wind slabs in areas you normally don't see them.
There were reports of numerous skier controlled dry loose and wind slab avalanches to size 1 and 1.5 on Sunday.
20 - 30 cm of new snow has accumulated over a crust at most elevations.
There is a layer of sugary facets that are buried 30-50 cm deep and in some places may sit on a crust. Avalanches on this layer are unlikely, but we continued to monitor its reactivity.
The lower snowpack contains a series of crusts and faceted snow that are more prominent in shallow areas in the east and north of this forecast region.
