Avalanche Summary

Dangerous avalanche conditions exists at upper elevations where strong winds drifted the new snow into thicker slabs on northerly and easterly-facing slopes. Avalanches in the new snow can grow large enough to bury or injure you on slopes with around a foot of new snow. Triggering an avalanche in the new snow could break into weak snow layers several feet deep on slopes facing west through north to east. Avoid areas beneath ridgelines and gullies where you see evidence of drifting such as fresh cornices, rounded pillows of snow, or where the snow surface is hard and sculpted. If you experience cracking or collapsing, retreat to slopes less than about 30 degrees that are sheltered from the wind.
