Avalanche Summary

No new avalanches were reported Tuesday or Wednesday morning. This will likely change as wind driven snow starts to accumulate.

Snowpack Summary

As of Wednesday morning, much of the region received 10-20cm of fresh snow accompanied by southwesterly winds, which has blanketed previously wind-affected surfaces (e.g. scoured crust, hard sastrugi, or stubborn wind slabs) in exposed areas, or around 20 cm of faceted snow in sheltered areas. The mid and lower snowpack are well settled and strong. The forecast shift in the weather means new wind slabs and storm slabs will be forming.
