Avalanche Summary

Dense new snow is adding stress to weak, collapsible snow layers 1 to 2 feet deep. The most dangerous slopes are steeper than about 30 degrees with around 10 inches of new snow. Avalanches triggered in the new snow could step down to weak snow layers several feet deep and produce a larger, more dangerous slide. Shallowly buried weak snow layers increase your chance to trigger an avalanche from a distance, so place a wide buffer between you and steeper slopes or large avalanche paths. Adjust your travels to low-angled slopes if you see signs of unstable snow like shooting cracks or audible collapses.
