You can trigger an avalanche that breaks near the ground. Beware of previously wind-loaded areas where dense, hollow-sounding slabs rest on weak snow. It will be difficult to see these areas with new snow and wind over the weekend. You can also easily trigger small avalanches near the surface where this weekend's storm snow accumulated on steep slopes. Both problems will likely be found in similar areas. Look for and avoid bulbous, textured pillows of snow on steep slopes. Especially on easterly-facing slopes just below ridgelines and in gully features. If you notice shooting cracks in the new snow, or if you are traveling on dense snow that sounds drum-like, move to lower-angle slopes.
Reduce your chances of triggering any avalanche by sticking to slopes less than about 30 degrees without steep slopes above you.
