Fresh snow brings fresh potential for wind slab formation.
Watch for changing conditions as you shift elevation and aspect.
Old wind slabs sit over a weak layer of facets, resisting bonding. New and more reactive wind slabs may form with fresh snowfall. Surfaces are generally heavily wind affected - look for signs of active transport or recent loading.
No new avalanches have been reported in the last 2 days.
On Saturday, small loose dry avalanches were reported on steep alpine terrain. Over the past week, several large wind slabs were observed on northeast, east, and south facing slopes, failing on a faceted layer beneath recent snow.
Light accumulations of storm snow overlie heavily wind affected snow in exposed areas. A layer of sugary facets is buried around 50 cm deep and is slowly gaining strength. Below 1300 m, a near-surface crust is present.
The mid and lower snowpack have no layers of concern. Snowpack depths are generally around 150-200 cm deep at treeline.
