Small wind slabs have formed over a crust. Pockets of wind affected snow can be found directly lee of high points and ridges.
Avalanche hazard is low.
Continually assess as you travel, and watch for isolated pockets of wind slab in lee terrain features.

There have been no recent reports of avalanches.
If you are heading into the backcountry, please share your observations with the Mountain Information Network.
A widespread surface crust is found at treeline and above, with isolated pockets of wind affected snow above it in lee terrain features.
Below this, moist snow is starting to refreeze, and depending on aspect and elevation, the top 20 to 30 cm may contain one or two crust/facet layers. These layers are expected to become increasingly problematic as they get buried deeper.
The lower snowpack is generally well settled, with no significant concerns.
