Be especially cautious as you transition into wind-affected terrain. Reactive wind slabs may be found on a variety of aspects.
The freshest wind slabs will likely be forming on north aspects as winds shift south on Tuesday. On other aspects, older wind slabs are likely to remain reactive as they sit over weak surfaces.
Small wind slab avalanches were observed on Sunday out of steep, rocky east and south aspects, as described in this great MIN report from the Babines. We are still awaiting field observations but suspect that with the additional snowfall on Sunday night, natural avalanche activity likely continued into Monday.
15 to 40 cm of recent snow sits over predominantly weak, faceted surfaces and may be slow to bond. At upper elevations, it has been redistributed by shifting winds. Check out this MIN report from the weekend, describing snowy conditions in high terrain.
Another layer of weak, faceted crystals and a crust are buried 20 to 50 cm deep.
The mid and lower snowpack is generally well-bonded and strong.
