You can trigger an avalanche on north to east through southeast-facing slopes at upper elevations. The most dangerous areas are slopes with cohesive wind-affected slabs and old mid-snowpack slabs resting over weak snow near the ground. Cracking and collapsing may not be present before you trigger an avalanche. You can find safer travel on terrain less than about 30 degrees that does not connect to steeper slopes above.
The next round of snow looks to start on Saturday. You can expect the avalanche danger to increase in favored areas. New snow could make weak surface snow and other weak layers in the middle of the snowpack susceptible to failure.
