More detailed information about the snowpack: 

3-4" of new snow seems to have fallen on Wednesday morning here.  Many places were stripped by wind to the old firm snow surface, and only slightly greater amounts found in deposition/catchment areas. Overall total snow depth 0-2.5ft.

SW winds increased throughout the morning up high up to strong, with some visible snow transport that seemed to be sublimating more than depositing over high ridges.

Variable surfaces from extremely firm and slick, some patches of ice even, to soft snow over facets in sheltered areas and soft snow over crusts of varying thickness... very little breakable at least!

No current stability concerns where I travelled today, but the firm surfaces will make for a good bed surface for avalanches to slide on during the large incoming storm. In widespread areas the upper-most underlying loose sugary facet layer appears to be consistently the weakest (whether buried under the crust of the old snow surface or just under the new snow without a crust ontop).  This facet layer will be quite a concerning weak layer with the incoming snow load.  A large avalanche could also possibly step down to the deeper firmer layer of facets.

Drove to the end of the VA Lakes Rd (9,800') and skinned up Red Lake Bowl up to the easterly facing ridge top of Black Mtn (11,600').  Much less new snowfall here from the Wednesday storm than around Mammoth, previous wind effects above treeline however appear to be much greater.  Lakes were quite frozen, with a thin snow cover.  Many places of challenging skinning conditions with the firm old surface layer either being exposed or buried by a few inches of soft snow.  Ski crampons would definitely have been useful, and ended up using boot crampons for the final few hundred feet to the ridgeline, even though the slope was not that steep.
