Avalanche Summary
No avalanches have been reported yet in the region, however early season conditions have been limiting observations of the backcountry.
Snowpack Summary
Light snowfall over Thursday and Friday brought recent storm snow totals to about 30-35 cm and total alpine snowpack depths to around 120-190 cm. The storm snow overlies a widespread layer of weak, feathery surface hoar crystals that formed during the clear period prior to the storm at treeline elevations and above. On steeper solar aspects, this surface hoar layer may instead exist as a thin sun crust below the storm snow. Below this layer, there is a basal crust from late October covering the ground. Snowpack depths taper quickly with elevation and below treeline elevations generally remain below threshold depths for avalanching
