Avalanche Summary

No recent notable avalanches have been reported.

Snowpack Summary

Surface snow in the past few days has undoubtedly become moist or wet on all aspects to mountain top with sunny skies and a high freezing level. Depending on the time of day, you may find the surface to be moist or be a frozen crust. The overall snowpack is well settled. Cornices formed or have grown more overhanging with the snowfall at the end of last week. They become touchier as they grow in size, as the temperature rises, and/or as they are impacted by the strong late-winter sun.
