Recent snowfall and easterly winds loaded slopes in unusual places. In steeper terrain, you can trigger an avalanche where stiffer slabs have formed below ridges or along the sides of cross-loaded gullies. Lower-angle, wind-sheltered areas are safer options.
Sunny slopes will pose a threat for mostly small, loose, wet avalanches. The concern will grow as the day progresses. Slushy surface conditions, pinwheels, and roller balls are indications wet avalanche activity is imminent, and it's time to move to shadier, colder slopes or exit avalanche terrain.
