Assess the snowpack before committing to larger slopes, the Dec 2 interface could still be reactive to skier triggering and could result in a large avalanche.
Weather Forecast
A ridge of high pressure will build over southern B.C today supporting cool and (relatively) wind-less conditions in the mountains. Mainly cloudy with isolated flurries (less than 1cm), with freezing levels to remain at valley bottom.
Snowpack Summary
30cm of recent storm snow now covers a supportive crust below 1600m. 60-80cm of settled snow now lies over the Dec 2 interface. Below treeline the Dec 2 surface hoar has showed no recent activity. On steep solar aspects above treeline Dec 2 is a sun crust and and remains reactive in stability tests in the mod - hard range.
Avalanche Summary
Avalanche activity has tapered off since Friday. The only recent activity that has been observed is out of regular performers in steep, 'unskiable', wind loaded gullies.
Problems
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.
