While snow and ice continued to fall in parts of the northwest, others in the region struggled with the aftermath of the same winter storm -- including floods, slick roads, power outages and avalanche warnings. The system itself remained a threat, with winter storm warnings from the National Weather Service in effect Thursday night for parts of eight states -- Washington, Oregon, California, Nevada, Utah, Wyoming, Idaho and Montana. Yet fresh precipitation was just one of many continuing concerns. Chief among them was flooding, particularly in western Oregon and southwest Washington.
