BOULDER, Co. (WTVR) -- Colorado can't catch a break. The rain continued Saturday, making it even more difficult for emergency crews to continue the search for missing residents.
Four people have been killed. A 60-year-old woman was presumed dead after witnesses watched her get swept away by flood waters that demolished her home, the Larimer County Sheriff's Office reports.
At midday Saturday, the Larimer County Sheriff's Twitter account said there were 100 unaccounted for. Now, the number has risen.
"We're assuming some of them have been stranded. We're assuming that some made their way out and simply haven't contacted us or friends and family to get off the list. We're assuming that there may be further loss of life or injuries," Boulder County Sheriff Joe Pelle said.
Colorado Governor John Hickenlooper went to the skies to see the damage. His surveillance flight was detoured for two rescues.
The nightmare is far from over, though.
Severe thunderstorm warnings were issued for eastern Denver and surrounding counties. The storms delivered almost 2 inches of rain in less than 30 minutes. While the warnings were for counties southeast of the flooded areas, the National Weather Service expected rain to move through most of the region Saturday evening. More rain is expected through Sunday as well.
There is concern that the additional rainfall will cause more flooding and dislodge mud and debris.
Governor Hickenlooper warned that a long road of recovery was ahead of the state.
"This is not going to get fixed in a week," he said. "We have lost a great deal of infrastructure."
