Avalanche Summary
Sluffing was observed in steep, shaded terrain. Otherwise, no new avalanches were observed.
Snowpack Summary
Around 5 to 10 cm of snow will fall onto a variety of surfaces, including wind-affected snow in exposed terrain at higher elevations, soft and faceted snow in shaded and sheltered areas, and a melt-freeze crust on steep southerly slopes.The middle and lower snowpack is well-settled.
Problems
Wind Slabs
Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
