Snowfall amounts for Monday afternoon into Tuesday are uncertain but may be enough to increase the danger rating.
Weather Forecast
Monday will be flurries yet models are not agreeing on the snow amounts with predictions of 0-12cm. Alpine temperatures will be -4 C and increasing SW winds. Click here for the Avalanche Canada mountain weather forecast.
Snowpack Summary
10-15cm of low density snow sits over a firm mid pack consisting mainly of facets. The primary layer of concern continues to be the October 25 crust 0-40cm off the ground. This crust is most prevalent in deeper snowpack areas predominately on N-NE lee features. Faceting above and below this layer continue to weaken the lower snowpack.
Avalanche Summary
No patrol Sunday and nothing new reported. Saturday's Hy 93 patrol reported no new avalanche activity. No natural activity has been observed in the last 5 days.
Confidence
Forecast snowfall amounts are uncertain on Tuesday
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.
