Watch for fresh wind loading, storm snow remains reactive to human triggers
Watch for reactivity in the wind affected storm snow on north and east facing slopes. Storm snow overlies large, weak surface hoar. Triggering is most likely at elevations where the rain crust disappears.
Potential for continued reactivity exists in areas where the rain crust thins, or does not exist.

Strong winds will redistribute 10-20 cm of recent snow into deeper deposits on north and east facing slopes. This snow covers a widespread crust from the rain. This rain crust is thought to extend to ridgetop in many areas, however we have limited observations in this area.
The greatest concern is a large and weak layer of surface hoar, found 40-60 cm deep. This surface hoar sits on a thin sun crust on steep south-facing slopes.
The mid-pack is generally well-settled. Lower in the snowpack a crust with weak facets beneath it can be found 20 cm off the ground.
