Primary Problem: Persistent Weak Layer
Bottom Line: The avalanche potential in the southern mountains is two fold: shallow wind slabs which are easy to see, feel and mitigate, and a deeply buried weak layer which is difficult to trigger. Even though the odds of triggering one are going down it is not out of the question. As we travel into avalanche terrain, it’s not just the layers near the ground we are concerned with. Stability tests are pointing out weakness near the surface, a potential problem with more snowfall.
