Avalanche problems should be limited to elevations that received new snow. Sunshine and warming will destabilize this snow on Thursday. Keep your guard up to prevent a small avalanche from ruining your day.

Avalanche Summary
No recent notable avalanches have been reported.
Snowpack Summary
After a period of light rain, new snow has begun to accumulate on the surface. Up to 15 cm of new snow can be expected in the alpine and the depth and reactivity of new storm slabs will likely increase with elevation. The new snow is accumulating on a variable surface of wet snow and crust.Below the surface, the overall snowpack is well settled and strong. New cornices formed and old ones grew more overhanging with the snowfall at the end of last week. Cornices become more unstable as the temperature rises and as they are loaded by rain and new snow.
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.
