New snow and wind loading has formed reactive storm slabs.
Make conservative choices and be very wary of exposure to overhead hazards, especially when the sun is out.
Storm slabs sit on facets, exposed crust, and sun-affected snow creating perfect sliding conditions for new avalanches. Significant wind will create large deposits in lee areas.
New storm snow is expected to become reactive with solar warming. Watch for natural wet loose avalanches, particularly on sun-exposed slopes.
A few natural wind slabs were observed in steep, north facing terrain on Sunday. No other recent avalanches have been observed.
Natural and human triggered avalanches remain likely on Tuesday.
Up to 25 cm of new snow overlies a mix of facets, exposed crusts, and sun-affected snow. Leeward aspects (north to northeast) may hold deeper and stiffer storm slabs due to wind loading during the storm.
A widespread crust/facet layer from late January is buried 60 to 90 cm deep.
The mid and lower snowpack is generally well settled and strong.
