In sintesi

The avalanche danger is LOW. With increased wind speeds last night and continuing through the day, evaluate snow and terrain carefully in locations where wind transported snow could accumulate and create wind slabs near ridgelines that may fail on a buried layer of facets. Stay away from thinner areas where you may find buried objects just under the snow surface.

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?

Snow and Weather

Skies are partly cloudy with temperatures in the high 20's and low 30's °F. Winds are blowing from the west 10 gusting to 20 MPH at the 8,000' ridgelines and from the southwest in the 15 gusting to the low 20 MPH at the 11,000' ridgelines. Today, look for increasing clouds. Temperatures will be 33-37 °F and dropping during the day with westerly winds blowing 5 gusting to 10 MPH at the 9,000' ridgelines and blowing from the west-northwest 35 gusting to 45 MPH at the 11,000' ridgelines. The freezing level will start around 10,000' and slowly drop throughout the day. There is a chance of snow on the horizon and we can look for 1"-3" of new snow and .05"-.20" of water by tomorrow morning.
