ESTES PARK, Colo. - Gov. John Hickenlooper says 16 or 17 helicopters will resume searching Monday for residents cut off by flood waters.
Speaking on ABC's "Good Morning America," he said he hopes that a majority of people unaccounted for are "safe and sound." However, he said, authorities expect the death toll to rise.
Four people are confirmed dead and two more missing and presumed dead after their homes were swept away.
Some 1,500 homes have been destroyed and about 17,500 have been damaged, according to an initial estimate by the Colorado Office of Emergency Management.
In addition, 11,700 people left their homes, and a total of 1,253 people have not been heard from.
With phone service being restored to some of the areas over the weekend, officials hoped that number would drop as they contacted more stranded people.
