Look for signs of instability like shooting cracks and avalanche activity.

Storm slabs may remain reactive to rider traffic.

Avalanche Summary

Wet loose avalanches up to size 2 were reported during the period of rain and warm weather at the end of last week.

Observations remain limited in this region. If you head into the backcountry, please post to the Mountain Information Network.

Snowpack Summary

10 to 25 cm of new snow from Friday’s storm overlies a crust on all aspects at treeline and south aspects in the alpine. Moist snow from previous rain and warm temperatures can be found below. At lower elevations a new crust will form on the surface as temperatures fall.

The lower snowpack contains a crust from early-November, possibly with weak facets around it. Its distribution and reactivity are unclear.

Treeline snow depths are highly variable.
