See above for Persistent Slab descriptors observed. Additional weight and loading over the next 24 hours may be enough to bring on a widespread avalanche cycle on all aspects at mid and upper elevations. Very dangerous snow pack structure in place. There was no significant loading occurring during the daytime hours, and as a result natural avalanches did not appear to be possible; yet due to the overwhelming and widespread nature of the PWL's in place, Considerable Danger appeared to be the danger rating in the zones traveled. With the potential for a quick 1.5 to 2 inches of water, and up to 2 feet of snow over the next 24 hours, it appears that the danger rating will rise to High by late afternoon and into the evening hours on Monday.

Old wind slabs were observed around treeline, and most appeared stubborn and unreactive. Forecast for increasing/moderate to strong S veering to W, and then NW winds most likely will escalate the Wind Slab Problem considerably, as there is ample snow available for transport. As a result Wind Slabs may be building on a variety of aspects and terrain features at mid and upper elevations. Any significant loading from these winds will also contribute to the potential for avalanches stepping down into the multitude of buried faceted layers previously described.
