Snowpack Summary
Up to 35cm of storm snow could accumulate up to Mon eve. Expect to find new wind slab on lee ridgetop features and below. The new snow will overlie previously wind affected surfaces in non-sheltered areas in the alpine and below as well as widespread surface facets. Strong mid-pack in deeper areas overlies supportive basal layers.
Avalanche Summary
Field team reports no new avalanche activity observed.
