New snow from earlier in the week will take a couple of days to settle and bond. In the meantime also pay attention to the direction of the wind as you travel through wind exposed areas – there is a lot of snow available to build wind slabs.

Avalanche Summary
On Tuesday there were a few reports of skier triggered storm slab avalanches to size 1 and 1.5. As well, there were explosives controlled avalanches to size 2 and 2.5 on southerly aspects between 1900 and 2100m.
Snowpack Summary
20-30 cm of new snow is being redistributed by southwest winds and sits on top of previously formed wind slabs in exposed terrain.
In terrain sheltered from the wind, small surface hoar crystals may be found 50-90 cm from the surface. At a similar depth, you may also find a melt-freeze crust on sun-exposed slopes and below 1900 m.
Deeper weak layers in the snowpack have not recently produced avalanches, but they may become reactive again if there is a rapid change in the weather.
The lower snowpack contains weak and faceted grains.
