Snowpack Summary
Little Prairie has 67cm snow . Summit Lake = 100 cm total. Instabilities within the 25 to 35 cm of storm slab and at the old snow faceted interface indicate skiers could trigger avalanches in steep unanchored terrain at higher elevation areas.
Avalanche Summary
Limited observations due to poor visibility.
Confidence
The weather pattern is stable
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.
