Looking forward to Tuesday, similar conditions are likely.

Snowpack Summary
With light snowfall and moderate wind continuing, expect up to 25 cm of soft snow on the surface in sheltered areas, and deeper deposits of wind slab in leeward terrain. Below this, expect to find firm wind-affected surfaces, hard crusts, or loose powder snow (primarily in sheltered north-facing terrain).
Large, fragile cornices can be found on exposed ridgelines and should be given a wide berth.
Below 1300 m the recent snow overlies a widespread melt-freeze crust.
