Volunteers from Chicago are on their way there to help the victims.
Food and water supplies are running low for communities cut off by flooding, but authorities say residents are holding their own while they wait to be rescued.
The American Red Cross of Greater Chicago is deploying two trained volunteers to join the relief efforts. One of them, Jackie DeLong, is a nurse.
"If there are shelters set up and they need a nurse for a shelter, I would go there and handle any medications, any first aid needs that would come up," said DeLong.
DeLong and the second volunteer are leaving for Colorado on Tuesday.
