In sintesi

The avalanche danger will rise to MODERATE on upper-elevation slopes as increasing winds will create sensitive soft slabs of wind-drifted snow on aspects facing northwest, through east, and southeast.

The avalanche danger is expected to rise by Saturday, with heavy snowfall and strong winds forecast for this weekend.

Increasing winds from the west will create fresh wind drifts at the upper elevations. Wind drifts may be sensitive as they will form on top of weak, faceted snow at the surface of the snowpack on slopes facing north through east and southeast.

On Thursday, Mark Johnston and I were finding widespread weak snow at the surface of many slopes. This is likely going to be a weak layer with any fresh wind drifts and storm snow. I describe what we saw in this video:
