There have been at least three deaths and hundreds of evacuees forced out of Fort Collins, Colorado Springs, and Denver, Reuters reports Thursday September 12.
Heavy rains have caused severe floods that stretch over 100 miles across the Eastern Slopes of the Rockies.
Emergency crews were searching door-to-door for people remaining after the evacuation. There were a number of casualties due to the storm.
Among the people that died in Boulder County, one person was found in a home that collapsed. The body of a third victim was found in Colorado Springs about 100 miles to the south, officials said.
Andrew Barth, a spokesman for the Boulder County Office of Emergency Management stated that conditions were “extremely dangerous” and an additional 4 inches of rain was expected to hit the area by day’s end.
"There is water everywhere," said Barth. "We've had several structural collapses, there's mud and muck and debris everywhere. Cars are stranded all over the place."
A flash flood warning has been issued by the National Weather Service for Central Boulder and Southeastern Colorado.
The University of Colorado's Boulder campus evacuated more than 400 students from ground-floor campus housing overnight, said Ryan Huff, a spokesman for the campus police.
During search-and-rescue efforts three people were rescued from an upside-down car that was swept into a washed-out culvert along a roadway with two other vehicles.
