Persistent weak layers that formed in November and December produced numerous deep and dangerous avalanches over the past 10 days. These avalanches ran during a period of high danger. Most avalanche accidents happen after the natural cycle is over, when the danger is dropping down to considerable, and eventually moderate. The natural activity may be over, but many slopes hang in the balance just waiting for a skier or rider to come along and trigger deep, dangerous, and deadly avalanches. The danger is most pronounced on above treeline slopes that face NW-N-NE-E. Humans are likely to trigger large avalanches on these slopes, especially in steep rocky terrain with a shallow snowpack. The snowpack is slowly gaining strength, but we need to give it more time to adjust. Continue to practice conservative decision making, and stick to slopes less than 30 degrees.
