While the likelihood of triggering a persistent weak layer avalanche has gone down, the consequences remain the same. It may not take much additional wind or new snow to tip the scales and it will be possible for a human to trigger an avalanche failing 2'-4' deep. This will be more likely in thin, rocky, locations on steep terrain (greater than 30°) facing west-north-east at mid and upper elevations. A couple of days ago there were reports of whumpfing and collapsing on lower angle slopes near Electric Lake. This is a surefire sign that the weak faceted snow could still avalanche in steeper terrain.
