On Thursday, a few loose dry avalanches occurred in steep and rocky alpine terrain on sun-exposed aspects.On Wednesday, large (size 2 to 3) wind slabs were observed in the region, being triggered naturally and by explosive control. They were generally on easterly aspects, 20 to 30 cm deep, and at treeline and alpine elevations.Cornices have also been reactive this week, with numerous releases from natural and explosive triggers.

Around 5 to 10 cm of snow fell on Friday.  Wind slabs may linger on all aspects at higher elevations, produced from the redistribution of last weekend’s storm snow with variable wind directions. This snow sits on a melt-freeze crust on sunny aspects and all aspects below 1600 m, as well as surface hoar on north aspects above 1600 m.  At ridgetop, cornices are large and have been failing in the past few days.  At low elevations, expect to find a surface crust or moist snow on southerly aspects.Deeper in the snowpack, the late-November weak layer is composed of weak and sugary facets around a crust, which is buried around 200 to 300 cm and considered dormant.
