Dense snow and wind may have been enough to form some areas of unstable snow. This new snow fell on weak preexisting snow. Dense wind blown snow on top of a layer of weak snow is a red flag. Watch for cracking and collapsing of the new snow and avoid steep slopes if you see this. The most likely places to trigger something will be on the mid and upper elevation north through east facing terrain but watch west aspects as well.
