Our deep layers are going to be with us for a long time yet. With no significant weather coming our way, we expect the hazard to flatline for the next while.
Weather Forecast
For tomorrow: Cloudy, alpine high of -7, no snow, moderate winds SW.
Avalanche Summary
Nothing of note here
Snowpack Summary
Not much change in the last 24hrs. Slightly more wind effect today, but not enough to be a concern just yet. To add to the list of crusts, a sun crust was noted today on south aspects above 2200m. How this crust is distributed is unknown right now, but it is on the radar. Stability tests today at treeline had mostly hard results, which is encouraging, but still not a promise of a solid snowpack. Snow depths at 2200m were 60cm's, with the Nov 6 crust on average 40cm's down. The basal snowpack is depth hoar.
Problems
Deep Persistent Slabs
Deep Persistent Slab avalanches are the release of a thick cohesive layer of hard snow (a slab), when the bond breaks between the slab and an underlying persistent weak layer deep in the snowpack. The most common persistent weak layers involved in deep, persistent slabs are depth hoar or facets surrounding a deeply buried crust. Deep Persistent Slabs are typically hard to trigger, are very destructive and dangerous due to the large mass of snow involved, and can persist for months once developed. They are often triggered from areas where the snow is shallow and weak, and are particularly difficult to forecast for and manage.
