Colorado flooding

The final six people who were unaccounted for after massive flooding in Colorado have been found safe and well, authorities said Tuesday, but new spills were reported in water-damaged oilfields.

From mountain towns east to the plains city of Fort Morgan, numerous Colorado communities remain cut off by flooding as rain continued to fall through the weekend and rescuers continued to make treacherous journeys up canyon roads to reach isolated homes.

The search for people stranded from the Rocky Mountain foothills to the plains of northeastern Colorado grew more difficult Sunday, with a new wave of rain threatening to hamper airlifts from the flooded areas still out of reach.

As rain keeps falling over Colorado, the threat of flooding is prompting emergency officials to issue evacuation calls to thousands more homes.

Heavy rains and scarring from recent wildfires sent walls of water crashing down mountainsides early Thursday in Colorado, cutting off mountain towns, forcing the University of Colorado to cancel classes, and leaving at least three people dead.
