Remember that moderate hazard still requires careful evaluation of snow and terrain.Get above the valley fog and enjoy the sunshine while it lasts!
Weather Forecast
High pressure ridge will persist today into Tuesday. Some valley fog, clear skies above it, cool temperatures and light alpine winds will be the main course for today. A weak disturbance will pass over the Province bringing cloud, light snow and warmer temperatures midday tomorrow
Snowpack Summary
Rain crust to 2100m. Above 2100m the upper snowpack is settling storm snow that is beginning to facet with the cold temperatures. Surface hoar growing at this time to 6mm. Snowpack tests yesterday on Bruins Ridge, east aspect produced hard sudden planar results down 25 and 50cm. Well settled mid-pack with 30cm crust/facet basal weakness (Nov 9).
Avalanche Summary
No new avalanches were observed yesterday.
Confidence
Due to the quality of field observations
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.
Persistent Slabs
Persistent Slab avalanches are the release of a cohesive layer of snow (a slab) in the middle to upper snowpack, when the bond to an underlying persistent weak layer breaks. Persistent layers include: surface hoar, depth hoar, near-surface facets, or faceted snow. Persistent weak layers can continue to produce avalanches for days, weeks or even months, making them especially dangerous and tricky. As additional snow and wind events build a thicker slab on top of the persistent weak layer, this avalanche problem may develop into a Deep Persistent Slab.
