You can trigger an avalanche on northerly and easterly-facing slopes. The most dangerous areas are slopes with cohesive wind-affected slabs and old mid-snowpack slabs resting over weak snow. Cracking and collapsing may not be present before you trigger a large avalanche. It is still possible to trigger slides from a distance so give runout areas below steep slopes extra space.
You can find safer travel on terrain less than about 30 degrees that does not connect to steeper slopes and in areas without a buried weak layer.
The next round of snow looks to start on Saturday. You can expect the avalanche danger to increase in favored areas. New snow will likely make other weak layers in the middle of the snowpack like buried surface hoar susceptible to failure.
