You can trigger slab avalanches on leeward slopes at upper elevations where strong winds will have snow. Look for obvious signs of instability like recent avalanches or cracks shooting through the snow. When in doubt, avoid upper elevation slopes steeper than 35 degrees. Near treeline, you can steer around smaller, shallow slabs near ridgelines.
Winds will shift south and southeast on Wednesday. Drifting and slabs forming with westerly winds on Tuesday. You may still be able to trigger avalanches in these recent slabs.
Example: Cracking and drifted snow can help you identify and avoid wind slabs in your terrain.
