After flood waters devastated Colorado mountain towns, officials announced on Sept. 14, 2013 that more than 500 residents of the area were unaccounted for, according to NBC News.
Authorities are working to locate these individuals, noting that this number could rise or fall quickly because communication resources in the area have been deficient.
Boulder County Sheriff Joe Pelle said, “We are assuming there may be further loss of life and injuries… Given the devastation on some of those canyons, it’s definitely a high probability,” according to NBC.

Colorado National Guard Lt. James Goff stated that 1,750 people and 300 of their pets have been rescued by the National Guard and U.S. Army division in Fort Carson, reports NBC.
Although the flood waters have begun to recede, rain is in the forecast, which could create conditions in which flash floods could ravage the area again.
According to NBC, the death toll due to the extreme weather conditions is now at four with many more believed to be trapped without food, water, or power.
