Wind effect is the critical factor. The safest, best riding may be in lower elevation terrain sheltered from the wind.
Confidence
Moderate - Wind effect is extremely variable
Weather Forecast
The weather pattern is changing as the recent dominating arctic airmass slowly shifts south allowing a more regular pattern of Pacific frontal systems in.Saturday/ Sunday/ Monday: Mix of sun and cloud with alpine temperatures near -6. Freezing levels 1100 m and ridgetop winds light from the West. Check out the full synopsis here: https://avalanche.ca/weather/forecast
Avalanche Summary
On Thursday, a natural size 2 wind slab avalanche was reported from an North aspect near 2500m. Explosive triggered cornice drops initiated numerous slab avalanches size 2.5 and one size 3 from the slopes below. They were initiated from NE-S aspects above 2500 m. The details of these larger avalanches did not state if they were persistent slabs or wind slabs. Regardless, the size and magnitude is very destructive. With winds switching directions, recently formed stiff wind slabs may still be reactive to human triggering on a variety of aspects.
Snowpack Summary
15-30 cm of recent snow has buried variable old snow surfaces. These surfaces consist of wind scoured or old wind slabs in exposed terrain, surface hoar in sheltered terrain, and widespread faceted (sugary) old snow. Recent moderate winds from a variety of directions has redistributed some of this new snow on leeward terrain, building reactive wind slabs. The layer of facets from mid-December is still reactive to snowpack tests in isolated areas but is generally considered to be dormant during this period of cold, dry conditions but its status may change as we head into a warmer, wetter period next week.
Problems
Wind Slabs
Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind 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.
