Recent new snow is being redistributed by northerly winds. It's going to be another cold one.

Up to 40 cm of recent, low-density snow sits atop a variety of old surfaces, including surface hoar, crusts and/or facets.

The mid and lower snowpack is generally weak with several layers of note. Of greatest concern are weak facets and/or depth hoar located at the bottom of the snowpack, particularly in alpine terrain.

Snowpack depths at treeline range from 60 to 150 cm.

Recent reports in the northern part of the region indicate thin wind slabs running to size 1.5 in alpine terrain.

If you go out in the backcountry, please consider sharing your observations on the Mountain Information Network (MIN).

• Avoid steep, rocky, and wind effected areas where triggering slabs is more likely.
• If triggered, wind slabs avalanches may step down to deeper layers resulting in larger avalanches.
• Be aware of the potential for surprisingly large avalanches due to deeply buried weak layers.
