Degrees of Avalanche Danger ?
Saturday’s snowfall was cold, dry, and fluffy, which makes a weak base for the wetter snow that fell Sunday. Rising temperatures and continued wind loading will provide a trigger for natural avalanches today, mainly in steep, wind loaded areas. Stay out of avalanche chutes and steep gullies, where snow tends to funnel and can pile up deep.
Natural and/or human triggered avalanches will tend to occur on slopes steeper than 25 degrees. The sliding surface will be density interfaces within the new snow, or the new/old snow interface where areas of buried surface hoar reside. Some slides may step down to wind slabs 30-60cm deep, which could lead to large and deadly avalanches.
Recent Avalanche Activity

Additional Info & Media
Even small slides can pile up deep. Stay out of gullies, depressions, and terrain traps. ALWAYS wear a beacon, shovel, and probe and know how to use them.
