A layer of surface hoar is down 50 to 90 cm and remains problematic where a significant crust is not found above it.
Reactivity and depth of problematic surface hoar layers vary across the region.

No new avalanches have been reported. There are very few field observations coming from this forecast area. Remember that a lack of avalanche reports does not necessarily mean a lack of avalanche activity.
If you go out in the backcountry, please consider sharing your observations on the Mountain Information Network (MIN).
Surface snow remains heavily wind-affected at higher elevations. A crust has likely developed on the surface with recent warm alpine temperatures.
The mid-pack contains several layers of note; a layer of surface hoar and a crust down 20 to 40 cm, a significant crust from the early December rain event down around 50 cm, and a second layer of surface hoar down 50 to 90 cm.
The base of the snowpack is generally facetted.
