We have a Persistent Weak Layer of sugary facets that formed over the last month and is now buried. There have been spotty natural avalanches reported. Snowpit tests show poor results with this layer failing. We've just had some wind and added more snow. These are all red flags. We've had a LOW avalanche danger for a long time. It is not LOW danger anymore. We need to adjust our habits accordingly. Things are going to be tricky. The snow surface varied greatly before last week's storm. This means some slopes will avalanche and others won't and there's no way to tell now which are the most dangerous. Sheltered locations hold some of the weakest snow.
