Persistent weak layers formed during November are buried 2-3 feet deep across all aspects and elevations. In most areas the entire snowpack contains weak structure lacking a hard slab formation, decreasing the likelihood of triggering an avalanche. Slabs could exist on isolated terrain features such as steep sun exposed slopes or previously wind loaded terrain. These areas could have increased sensitivity to avalanches.
