Avalanche Summary

No new natural avalanches have been reported. A few small (size 1 to 1.5) slab avalanches were reported on Saturday as having occurred more than 48 hours ago.

Looking forward, the main concern will be the potential for lingering wind slabs on lee features in the alpine. Check out this MIN for more details.

Please consider sharing your observations through the Mountain Information Network.

Snowpack Summary

Above 1500 m, 10 to 30 cm of recent storm snow has been redistributed by strong southwest winds. Below 1500 m, a crust exists on or near the surface.

The remainder of the snowpack is dry, with small faceted crystals to the ground. 

Snow depths vary significantly, between 70 to 130 cm around the White Pass.
