Storm slabs are possible to trigger at upper elevations. Use caution on slopes getting hit by the sun.

Avalanche Summary
No new avalanches were reported at the time of publishing on Saturday.On Friday, skiers triggered several small (size 1) slab avalanches at upper treeline elevations and in lee alpine terrain. A few small loose dry avalanches were observed on south-facing slopes when the sun came out in the afternoon.
Snowpack Summary
20 cm of low density snow sits above sun crusts on south-facing slopes and hard wind affected snow in the alpine. Deeper deposits may be forming in wind-affected alpine terrain. In sheltered areas, 20 to 40 cm of low-density faceted snow is gradually settling onto old hard surfaces including crusts and wind-packed snow. Low-density snow may sluff easily on these hard surfaces. The lower snowpack is strong and settled.
Problems
Storm Slabs
Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-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.
