Watch for reactive storm slabs to form as the new snow settles. Tricky conditions still exist due to a touchy buried weak layer. Conservative terrain selection is critical.
Summary

SUNDAY: sunny with cloudy periods, light westerly winds, 1300m freezing level. MONDAY: sunny with cloudy periods, light westerly winds, freezing level around 2500m, +5C at 2000m.
Avalanche Summary
The recent storm snow is becoming increasingly reactive with numerous small natural and skier controlled avalanches reported in the last two days. Although there haven't been any persistent slab avalanche reported recently I think it could still be possible to trigger large destructive avalanches in isolated open, unsupported terrain features at and below treeline.
Snowpack Summary
Up to 30cm of new storm snow is settling to form a widespread soft slab. Moderate southwesterly winds on Thursday formed fresh wind slabs in lee features at treeline and in the alpine. Bellow 1900m a crust may be found about 50cm below the surface although this layer seems to be most prevalent in the Monashees. In the far south of the region a layer of surface buried at the end of January may be found at around this depth in isolated features at treeline and in the alpine. Deeper in the snow pack, the surface hoar layer from early January is now down 80-120cm in most places. Although this layer has become harder to trigger and is variably reactive in recent snowpack tests, it still has the potential to produce large avalanches. I would continue to show respect for this layer especially in steep, open terrain at treeline and below through the weekend.
