On going strong south west wind is building wind slabs. Expect to find these near ridge crests and below steep roll overs .
Warming temps will rapidly settle new snow, increasing the chance of human triggering.
As the avalanche danger increases, the solution is simple: choose conservative terrain.

Even a small wet loose avalanche can have enough power to push you into or over a terrain trap such as a cliff or ditch. Dial back your terrain selection when rainfall occurs on dry snow.
Storm and wind slab avalanches were reported size 1 to 2.5 over the past three days, triggered naturally, by humans and explosives. Most were on northwest to northeast aspects at upper elevations.
Up to 25 cm of snow on Monday is being transported and building new and reactive wind slabs.
The prominent mid-December facet/crust layer is buried over 1 m deep and extends up to 2200 m. Triggering the crust is considered unlikely, except with large loads or in thin snowpack areas.
