Snowpack Summary
New snow is accumulating above 10 to 15 cm of recent snow. Strong southwest wind will likely form drifts and wind slabs in exposed areas. Beneath the recent snow you may find hard wind-affected snow at higher elevations, soft faceted snow in shaded and sheltered areas, and crusts on steep southerly slopes. The middle and lower snowpack is well-settled.
Problems

Fresh slabs will form at higher elevations as snow accumulates throughout the day. Forecast snowfall amounts are variable, so pay attention to how much it snows in your local area.
Avoid freshly wind loaded features.Minimize exposure during periods of heavy loading from new snow and wind.Watch for whumpfing, hollow sounds, and shooting cracks.
