A buried persistent weak layer of facets that formed in January and February remains our biggest concern. There is still a chance a person could trigger an avalanche that breaks three feet deep down to the weak layer. The other concern is that the very warm temperatures will weaken the entire snow pack and cause natural avalanches breaking down to the same layer. The most likely place for human triggered avalanches is upper elevation northwest, north, and northeast facing steep slopes. The most likely places for heat related natural avalanches will be on east facing terrain in the mid and upper elevations and then west facing terrain later on.
