High-elevation wind-loaded slopes are the most concerning. You can easily trigger small avalanches where you find around a foot or more of recently fallen snow resting above granular weak snow near the ground. The most dangerous slopes face north and east below ridgelines and in steep wind-drifted gullies. Soft new snow will make it harder to spot the worrisome patches of old snow, so keep an eye out for cracking or collapsing as a clear indication of this problem.
