At least three people have died from flash floods due to heavy rain in Colorado Thursday.

Heavy downpours began Monday and continued to get worse Tuesday and into Wednesday spreading over 130 miles of eastern Colorado. The areas being threatened start in Fort Collins near the Wyoming border and continue south through the towns of Denver, Boulder, and Colorado Springs.

Boulder County, where 6-8 inches of rain has fallen, was hit the hardest. Officials expect at least four more inches of rain to fall Thursday before the end of the torrential downpour.

Two people died from flooding in Boulder County, one body was found in a home collapsed from the water. Officials then found a third man dead in Colorado Springs.

"There is water everywhere," said Andrew Barth, the emergency management spokesman in Boulder County, Chicago Tribune reports. "We've had several structural collapses. There's mud and muck and debris everywhere. Cars are stranded all over the place."

Over 400 students were evacuated from the University of Colorado Boulder’s main campus, which will remain shut down Thursday and Friday. Throughout the threatened areas, hundreds of residents have been evacuated.

According to USA Today, the National Weather Service has issued flash flood warnings for North Jefferson and Boulder counties, and have urged people to move to higher ground.
