Avalanche Summary

No new avalanches reported Monday. This will likely change as wind driven snow starts to accumulate Wednesday.

Snowpack Summary

Previous winds have either deposited snow in lee areas, with a few stubborn wind slabs, or scoured down to a mid-February crust. Cold temperatures have faceted the top 20 cm of the snowpack where it wasn't wind hammered. 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.
