Avalanche Summary
A skier remotely triggered a size 2 slab on a NE aspect at 2100 m on Tuesday. It failed on facets. Watch for new storm slabs and wind slabs forming on Thursday. Storm slabs or cornice fall could potentially step down to a buried weak layer, creating a surprisingly large avalanche. New snow may sluff easily in steep terrain.
Snowpack Summary
Recent snow and moderate winds have created touchy slabs in specific terrain. Cornices are reported to be large and fragile. New snow overlies various old surfaces including melt freeze crusts on sunny aspects, scoured old hard wind slabs and dry snow.A weak layer consisting of surface hoar, facets or a sun crust buried in late March is now down about 60-80 cm. This is patchy in its distribution, but is mostly likely to be problematic on shady aspects between 1900m and 2250m. The mid and lower snowpack are strong and well settled.
