Snowpack

It appears that between 4-6 PM around 4" of snow accumulated. (This is estimated by the amount of snow on the road while one of the plow drivers changed a blade.) This high PI event triggered a handful of small Storm Slab avalanches near the highway. At 5:30 pm daytime new snow totals on 550 North were: Red Mountain Pass 9"/0.65" and Monument 6.5"/0.45"
