Avalanche Summary
No new avalanches have been reported in the region. We anticipate those who head into the backcountry for the holiday will see evidence of a natural avalanche cycle from within the storm.

Snowpack Summary
Storm snow totals are expected to be 50-70 cm by Tuesday afternoon. Strong southerly winds continue to build thick wind slabs in exposed leeward terrain. South facing slopes (windward), have likely been scoured by the strong winds or have dense, wind packed snow.
Below 1200 m, a thick crust is present approximately 50 cm above the ground. This crust is well bonded to the snow around it.
The middle and lower snowpack is reported to be well settled and bonded. Snow depth varies from 75-200 cm through this region.
