Seems to be the foremost concern for tomorrow.

Persistent Weak Layer

Decreasing Danger
Problem #2 Comments: 
Obviously still a threat on slopes that have avalanched this season. It will be interesting to see if this problem emerges in areas with the full season's snow pack in place. Snowpit: 200 ft. below Sinner's Pass approaching via Mineral Basin. Quick "cheater" pit on the edge of the cat track (may have influenced historical temp gradient). ECTN
