Warming temps and moderate SW winds have created a soft storm slab at all elevations.
Be suspect of surface snow that feels heavier/stiffer, like around ridgecrests and cross-loaded features.
Watch for "mashed-potato" consistency storm slabs at low elevations, especially in steep-sided gullies or convex rolls.
Be extra cautious on South through West aspects, where there is a sun-crust down 40-70cm that has been reactive to skier/rider traffic.
Recent snow, accompanied by variable wind and mild temps, has created a soft slab that is most reactive near ridgelines and on convex slopes at lower elevations. Above Tree-line these storm slabs are present in lee features and a bit more stubborn to initiate.
A field team was able to ski cut a few convexities on solar aspects the last 2 days, producing up to sz 1.5 soft slabs running 30-40cm deep on the Jan 3 melt-freeze crust. These slabs were more reactive below Tree-line.
A natural sz 2 storm slab, ~30cm deep, 20m wide, 200m long, was observed from an Alpine start zone in the Connaught Path today.
Near neighbours are also reporting human-triggering of a soft slab, ~30-50cm deep, on unsupported rolls/features.
Warm temps and 30cm of settling storm snow are creating a soft storm slab on top of variable wind effect in open terrain at/above Tree-line, and faceted snow in sheltered areas below Tree-line.
A sun crust (Jan 3), down 50cm and most prominent at and below Tree-line on S-SW aspects, has been the failure plane for recent human triggered avalanches.
The Dec 1 surface hoar layer is down ~110cm and is decomposing.
Weak storm fronts will bring light snow, moderate winds, and mild temps the next few days.
