Rain-on-snow floods to increase in mountains, CU Boulder researcher says

In a warmer climate around the end of the century, rain-on-snow flooding could more than double and increase the risks for people living in certain sections of North America. The risk would increase most in mountainous regions, namely the Sierra Nevada range in California, the Colorado River headwaters and the Canadian Rocky Mountains, according to a study published this week by researchers at the University of Colorado and the National Center for Atmospheric Research. But the chance remains to mitigate the most severe consequences.
