There is a persistent weak layer of old, weak, and faceted snow from November near the ground. It has a thick slab on top of if from last weekend's major storm plus just a few inches from yesterday's storm. Avalanches on this layer will be deep and break over huge areas. Without major loadingyesterday, avalanches on this layer will be difficult to trigger today, and many slopes already avalanches and haven't refilled with much snow.
