Continue to be cautious. Very large avalanches may still be triggered. Be wary of open planar slopes, thin areas where deeper layers may be triggered, and slopes that did not avalanche in last weeks cycle.
Weather Forecast
Today will be cloudy with isolated flurries, with a high of -11'C and moderate SW winds. Wednesday will be a mix of sun and cloudy, with a high of -3'C. Thursday will be cloudy with sunny periods and freezing levels will rise to 1200m.
Snowpack Summary
Cold temps have tightened up the wet slab for now but are also weakening the snowpack over time. When temps rise, layers are expected to wake up again. Snowpack tests on two touchy weak layers buried down ~100 and ~130cm continue to indicate the may be triggered by skiers and produce very large avalanches. A hard rain crust exists below ~1600m.
Avalanche Summary
No new avalanches have been observed over the past 72hrs. Prior to the cold snap, a widespread avalanche cycle occurred. Large avalanches, with wide propagations, demonstrated the potential of buried weak layers. Some areas have not yet avalanched, for example the Frequent Flyer path up the Connaught Drainage.
Confidence
Due to the number of field observations
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.
