Helicopters resumed search and rescue missions, helped by clearer weather after days of torrential rain that has left over 1,500 homes destroyed and more than 17,000 damaged.
Five teams from the Federal Emergency Management Agency (FEMA) are bolstering hundreds of state and local officers trying to reach hundreds of residents stranded by the floods, centered on Boulder County north of Denver.
"We have a strong opportunity here, with FEMA's help, to come out of this whole sitaution with a strogner infrastructure," Colorado Governor John Hickenlooper told a press briefing yesterday.
But yesterday there was even blue sky in places, allowing some 21 helicopters to take to the air.
"We are hoping to take advantage of the weather today and get those rescue operations complete," spokeswoman Micki Trost of the Colorado Division of Homeland Security and Emergency Management was quoted as saying by the Denver Post.
In all seven people have died, including three in Boulder County, two in El Paso County and two missing presumed dead in Larimer County, said the Colorado Office of Emergency management (COEM) in its latest update.
In all 11,700 people have been evacuated, the COEM said. A total of 17,994 residential structures have been damaged, and 1,502 destroyed.
Many of the missing may simply be unable to report their whereabouts, but Hickenlooper warned that the death toll may increase. "There are many, many homes that have been destroyed," he said.
Rain began pelting the western state early last week, with Boulder especially hard hit, seeing 7.2 inches (18.3 centimeters) of precipitation in about 15 hours starting Wednesday night.
"We've got a heck of a lot of communities dealing with a heck of a lot of water," Jennifer Finch, a spokeswoman for Weld County northeast of Boulder, told Denver Channel 7 News on Sunday.
On Sunday, traffic on Interstate 25, Colorado's main north-south thoroughfare just east of the mountain range, was brought to a halt by water covering two of the three southbound lanes, according to an AFP correspondent on the road.
Although skies were clearer yesterday, weather forecasters warned that scattered storms could still dump up to an inch of rain in less than 30 minutes, according to KUSA-TV.
Drier, warmer weather conditions are due to return to the battered state today, lasting through to Thursday when there is a chance of showers through the region, it said.
