Older slabs formed earlier this week now seem stubborn to skier triggering, but setting one off is not entirely out of the question. New slabs formed today will be shallow, but quite sensitive. Strong winds are forecast to blow tonight and tomorrow with the incoming snow. Any new snow we receive will be easily blown and drifted into fresh slabs, and we could potentially see new wind slab formation up to a foot deep. It all depends on how much snow falls with this storm.
1F density older windslab that pulled out easily with hand shears. You can see how it failed at the Graupel interface.
I found plenty of older, stiff wind slabs on test slopes like this one. They were stubborn to react to my weight as I skied over them, and I couldn't get anything to crack out or slide.
