Assess the bond between new snow and the underlying crust as you gain elevation. New wind slabs may not bond well and be more reactive as a result.
A couple of skier-triggered avalanches surprised a ski touring group on Saturday. Both avalanches were reported as size 2 and occurred on a northeast, alpine slopes just below a rocky ridge top.
If you go out in the backcountry, please consider sharing your observations on the Mountain Information Network (MIN).
5 to 15 cm of recent snow has fallen over a thin crust below 2000 m and wind effected surfaces above this elevation. In sheltered north facing terrain at treeline and above, this new snow is likely soft and makes for good skiing.
The mid and lower snowpack consists of various crusts and layers of facets or surface hoar. Reports indicate these are not currently a concern.
Mostly cloudy with 2 to 8 cm of new snow expected, south alpine wind 15 to 30 km/h, treeline temperature -2 °C.
Mostly cloudy with around 5 cm of new snow expected, south alpine winds 20 to 40 km/h, freezing level rising to 1600 m.
Cloudy with trace amounts of new snow expected, south alpine winds 20 to 40 km/h, treeline temperature -2°C.
Mostly cloudy with trace amounts of new snow expected, south alpine wind 20 to 40 km/h, freezing level rising to 1400 m.

Terrain and Travel Advice
- Be careful with wind slabs, especially in steep, unsupported and/or convex terrain features.
- Closely monitor how the new snow is bonding to the old surface.
- Small avalanches can have serious consequences in extreme terrain. Carefully evaluate your line for wind slab hazard before you commit to it.
Ongoing snowfall and southerly wind will likely keep the wind slab problem active. Wind slabs may be more reactive where they overlie facets or a crust.
