LITTLE ROCK — Three disaster responders from the American Red Cross in Arkansas have been deployed to Colorado to provide emotional support for residents coping with the trauma of a week of flash floods and evacuations, the agency said Monday.

Roger Elliott, state disaster officer for the American Red Cross in Arkansas, said the three responders deployed from the state are trained professionally as mental health workers.

"Their Red Cross experience spans from providing care to Arkansans affected by residential fires and tornadoes, to the recent floods that killed five persons in Scott County this past May, to the Oklahoma tornadoes and Hurricane Sandy," he said.

Catastrophic flooding in Colorado has left at least five people dead and more than 1,200 unaccounted for, Colorado Sen. Mark Udall said Monday as rescue crews prepared to mount what the Colorado National Guard called the largest civilian helicopter mission since Hurricane Katrina.
