These observations document past conditions at a small and variable scale. They are not to be confused with an avalanche forecast. They come from a variety of sources. We can only vouch for the quality of those produced by the SAC forecasters and professional observers.

Settlement cones around around trees indicated settlement and consolidation in the storm snow. Settlement cones around around trees indicated settlement and consolidation in the storm snow. Areas typically wind loaded by SW winds had been scoured by NE winds. As the winds switched back to the SW this afternoon they started to get wind-loaded again. Lenticular clouds and more consistent cloud cover moving into the area ahead of the next storm. Evidence of wind scouring by NE winds.
