You can expect 5-10cm of new snow from Sunday morning's squall. Strong South and SW winds were happening all day on Sunday, so expect new wind slabs near ridgeline and lee features. Under this storm snow, expect a firm crust on all aspects. If the sun shows it's face on Monday, moist snow will develop.
