Avalanche Summary

Warm sunny weather over the weekend caused wet loose avalanches. Most were small, but a few larger (size 2 to 3) wet avalanches were reported in the Purcells.

Snowpack Summary

Cooling temperatures will form a surface crust on all aspects above 1300 m. The upper snowpack consists of various melt-freeze layers. The lower snowpack contains old weak layers that are no longer a concern.

Terrain and Travel Advice

A crust on the surface will help bind the snow together, but may make for tough travel conditions.
Make observations and assess conditions continually as you travel.
