Poor snowpack structure remains, and it has proven capable of producing large, destructive human-triggered avalanches. The likelihood of triggering one of these avalanches is decreasing, but the consequences remain severe. Any avalanche failing on the PWL will take out the entire season’s snowpack and will instantly be a season-ender, or worse. The weak layer of concern is right below the Christmas rain crust. In some locations, this crust may temporarily support the weight of a skier or rider, but its ability to bridge underlying weaknesses is highly variable and unreliable.
If you are considering venturing into avalanche terrain start off with small pieces. Avoid slopes with steep convexities and terrain traps, as well as thin rocky areas and slab margins. This problem can be avoided altogether by sticking to slopes less steep than 30 degrees.

This extended column test, performed on a north aspect near tree line at 10,800 feet, scored ECTP30. Failure was on facets beneath the clearly visible, Christmas rain crust. For more details and a full profile, see my observation.
