Persistent weak layers (PWL) of faceted snow that formed in November and December remain our primary concern. The likelihood of triggering an avalanche on a deeply buried PWL continues to decrease, but it is still possible. We are now in a low likelihood, high consequence scenario. If you are stepping out into avalanche terrain, evaluate each slope on an individual basis. Aim to ride in areas with a deep snowpack. Avoid steep, rocky terrain, thinner areas along slope margins, and steep, blind rollovers or convexities. These are all likely trigger points.
