Very small (0.5) avalanches were reported in the area around sun peaks at lower elevations.
If you head into the backcountry, consider sharing your observations with the Mountain Information Network.
Up to 10 cm of new snow has been accompanied by moderate southwest winds yesterday.
This new snow will add to the 10 to 20 cm that has accumulated over the past few days all of which may be sitting on a thin crust on steep southerly aspects, as well as surface hoar in isolated, sheltered areas.
A mid-December crust lies 30–50 cm deep, found up to 2200 m. Additional crusts exist in the mid and lower snowpack, including a mid-November crust with facets above and below, but neither of these layers is currently a concern.
