GENERAL AVALANCHE ADVISORY
Riders and skiers could trigger wind slabs in steep avalanche terrain and also have the potential to trigger large, dangerous hard slabs. The likelihood to trigger either of these events will greatly increase as sunlight and warming weaken these slabs. At all elevations, small wet slides will be possible this afternoon.
Dangerous hard slab avalanches with depths of four to eight feet could be human triggered in areas where weak faceted snow persists deep in the snowpack. Predicting the failure of these slabs is extremely difficult as entire slopes may fail even after they have been tracked several times.
Dense winds slabs up to two feet in depth could be human triggered on steep wind loaded slopes. These surface slabs could step down and trigger deep hard slabs. The likelihood of triggering these slabs will increase today.
