Snowfall amounts are uncertain. If there's heavy snowfall in your area, the local avalanche danger may be higher than posted.
Confidence
Poor - Forecast snowfall amounts are uncertain for the entire period
Weather Forecast
Wednesday: Light to moderate snow. A period of intense snowfall is expected in the afternoon. Strong to extreme SW winds. Alpine temperature near -4.Thursday: Light to moderate snow. Light to moderate SW winds. Alpine temperature near -14.Friday: Light to moderate snow. Light winds. Alpine temperature near -11.
Avalanche Summary
On Monday, numerous loose snow avalanches to size 1 failed naturally in steep terrain. Natural avalanche activity is particularly likely at times of intense loading on Wednesday.
Snowpack Summary
New storm slabs may develop during Wednesday’s forecast storm. Wind-loaded slopes and spill zones (fans where snow accumulates below steep faces) may be particularly touchy. A buried rain crust may provide an easy sliding surface for avalanches. This crust is supportive to at least 2100 m in most areas and is up to 9 cm thick. It’s thought to be strong enough that snowpack weaknesses below it won’t be affected by the load of a person, with the caveat that there may be isolated exceptions (e.g. thin spots near rocks at high elevations). The mid-pack is generally well-settled. Cornices are large and fragile in some areas.
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.
