New snow along with wind drifted snow will increase the chance of triggering an avalanche that breaks into old weak sugary faceted snow buried deeper in the snowpack. Snowpit tests continue to show that the weak snow deeper in the snowpack can fail. The tests I did on Sunday were pretty stubborn to get to fail but still fully propagated through the weak snow.
The storm ended up doing ok for the Skyline giving it 8 to 11 inches of new snow by the time it was all said and done. Northwest wind on Sunday continued to be a bit more gusty than I anticipated. This means that the new snow will have been blown into drifts in many areas especially near the ridges. The wind was getting down into the canyon bottoms as well.
We'll see clearing skies today with ridgetop high temperatures in the upper teens and moderate speed northwest wind. High pressure moves in through most of the week with warming temperatures and mostly clear skies. It looks like there is some sort of weather disturbance toward the end of the week.
Fresh wind drifts will probably still be somewhat sensitive today. While there may be some fresh wind slabs that crack out today, an avalanche that breaks into old snow is by far the biggest concern.
