Red Flags
Red Flags: 
Recent Avalanches
Wind Loading
Collapsing
Poor Snowpack Structure
Red Flags Comments: 
Observed collapsing once again today in a couple of isolated areas. Besides this, efforts at attempting to initiate remote triggering in safe likely areas were not successful. Reports of avalanches in the past 24 hours continues. Poor snowpack structure noted below in photo and snowpit results. At this point the upper elevation protected terrain in the Brighton Perimeter appears to be bridging the buried weak layers as the snowpack has adjusted to the Christmas storm load. Despite this, confidence remains low to get out onto steep terrain on NNW, N, NE and E aspects.
