Colorado Flooding: 3 Dead, Mountain Towns Cut Off Heavy rains sent walls of water crashing down mountainsides Thursday in Colorado, cutting off remote towns, forcing the state's largest university to close and leaving at least three people dead across a rugged landscape that included areas blackened by recent wildfires. A warm, moist storm system has been dropping rain on the region for much of the week. Up to 8 inches fell in an area spanning from the Wyoming border south to the foothills west of Denver. Flooding extended all along the Front Range mountains, including the cities of Colorado Springs, Denver, Fort Collins, Greeley, Aurora and Boulder. "A slow-moving area of low pressure over the Rockies combined with a moist, southerly flow at all levels of the atmosphere will keep the threat of locally heavy rain and flooding in place into the weekend," said weather.com meteorologist http://www.weather.com/news/weather-severe/flash-flood-swamps-boulder-northern-colorado-20130912
