Whether you call it Storm Slab or Persistent Slab, the potential for Avalanche Activity with the Weak Layer of concern being the Weak Surface PreStorm Snow appears to be very possible. Poor bonding to the NSF's and Possible SH that were buried at the beginning of this Event appears to be of concern with possible Slides being up to at least 2 Feet and more in depth by mid day on Christmas. This instability may linger well into the coming week due to the nature of the these buried Persistent Weak Layers.
Regardless of no Natural Activity observed during this day of poor Visibility, the possibility that there were Naturals appears to be certain. And, after another night of Moderate to Strong Winds combined with the possibly of another Foot to Two Feet of additional Snow Fall, the Considerable Danger from Saturday may be inching towards High on Christmas Day.
