Spring sun is having an effect on the snowpack.
Watch for loose avalanches from steep, rocky terrain when the solar radiation is strong in the afternoon.
Wind slabs are lingering in isolated alpine terrain features. As you transition into the Alpine, be mindful of changing conditions and signs of instability like cracking, whumpfing, or hollow-feeling snow below your feet.
Isolated natural avalanches observed Wednesday along the highway corridor up to size 2.0 from the steep terrain off Mt. Macdonald.
Several solar-triggered avalanches were observed Tuesday from S faces (Lone Pine, Mounds, Lens, Tupper Minor paths), from sz 1.5-2.5.
Diurnal temperature fluctuations has produced crust on solar aspects, which break down during the warmest part of the day. Isolated wind slabs in the alpine.
40-60cm of settled snow overlies a layer of decomposing stellars (large new snow crystals), a crust on solar aspects, or a thin layer of facets.
Although generally strong, the snowpack still sits upon a deep persistent weakness of rounding facets and a decomposed crust near the ground.
Prime spring-like weather continues Thursday, with an upper low arriving Friday bring snowfall.
