You'll find areas where the wind drifted the most recent new snow forming some slabby areas in the higher terrain. These fresh drifts and slabs don't seem to be all that sensitive.
The bigger issue is older larger wind drifts that are sitting on top of weak sugary snow. A lot of these appear to be welded into place and are very stubborn to trigger. However, some will be easier to trigger. The problem is that it is difficult to differentiate between which ones will stay in place and which ones won't. The fresh snow from the weekend hid many of these drifts. Also, you can't tell if the drifts are sitting on top of weak sugary snow just by looking from a distance. This makes assessment difficult.
Here's the deal. Sugary faceted snow is known to be very tricky and will produce avalanches when you think things are stable. This is why we call it a Persistent Weak Layer. My strategy is that I don't mess around with steep slopes when there are widespead layers of sugary faceted snow in the snowpack just like what we have right now. Keep your slope angles under 30˚, and you'll stay safe.
