Avalanche Summary
Over the past few days numerous small natural and skier triggered wind slabs have been observed in immediate lee features. Several small natural cornice falls have also been reported.
Snowpack Summary
Up to 70 cm of recent storm snow with strong to extreme southerly winds has likely formed wind slab on west through east aspects at upper elevations. These winds have also scoured exposed windward slopes. As the freezing level falls a new crust will form on all aspects at treeline and below.
A crust from early April can be found down 50 to 80 cm on all solar aspects and at treeline and below on north facing terrain. Below this crust the snowpack is generally well settled.
