Update: The number of people unaccounted for was reported at just over 700, as of 9am Monday.

Helicopters were prevented from conducting additional search and rescue efforts in Boulder and Larimer counties. Thousands are still unaccounted for, and just as many remain stranded in mountain communities cut off by washed out roads. Government officials are still getting a handle on unprecedented levels of destruction.
