Avalanche Problem #1
Problem
Persistent Weak Layer
Trend
Increasing Danger
Problem #1 Comments
I think increasing danger because as the snow stability gradually increases, slopes that didn't yet avalanche may allow people to get out in/on them before releasing.
Avalanche Problem #2
Problem
Wind Drifted Snow
Trend
Increasing Danger
Problem #2 Comments
Drifts that build on the faceted snow in steep terrain will likely to produce avalanches.

Comments
I observed numerous natural avalanches from overnight 12-17/18-2020. And, there were also a few avalanches remote triggered by different parties during the day, some of these were triggered from quite a distance. "user friendly" and foregiving conditons when slopes avalanche when you are approaching them, or just looking at them, and when they avalanche before you commit.
