The persistent weak layer (PWL) making up most of the snowpack on the north side of the compass continues to lose strength. As we get new snow or wind, this structure is not going to be able to support much weight and will start to collapse. Take a look around and make note of what slopes, aspects, and elevations are and are not holding snow so you'll have an idea of locations to avoid once we get our next storm. Weak snow is also forming on the surface and you can learn more about surface hoar HERE. The question is whether or not the warmer temperatures and wind will destroy this surface weakness before it snows?
