Five volunteers from Arizona are now in Colorado, helping the state deal with horrible flooding conditions.
The governor of that state has declared a state of emergency for many counties north of Denver.
The images from Colorado are unreal. What were small streams are now raging rivers. Streets are flooded over and damaged.
Some residents are even stranded -- having to be airlifted to safety.
While Colorado braces for the possibility of more rain, Red Cross volunteers from across the nation, including here in Arizona, are headed there to help.
"I'm going as a liaison for the emergency operation centers," said Dave Curtis, who left Sky Harbor Airport on Saturday morning.
"There's currently five of us going this weekend, so by this afternoon, five of us will be in Denver and more than likely, there will be more Grand Canyon volunteers following," he said.
Once they arrive, the volunteers from Arizona will be dispatched to an area in Colorado where they're needed.
"In Red Cross terms, this is a big disaster. Every disaster is different. You really can't compare them. It's like comparing apples and oranges. But this is a big one and it's going to require a lot of support from the American people and from Red Crossers across the nation," said Trudy Thompson.
The local chapter of the Red Cross says it's likely they'll send even more volunteers to Colorado in the coming weeks. For most of these volunteers, like Curtis, they say helping those in need is rewarding.
"You have to focus on helping the people. That's what you have to focus on. That's why we're there," said Curtis.
The volunteers from Arizona will stay for about three weeks before returning home. Right now, Colorado is asking for nurses, mental health workers and case workers.
