The flooding in Colorado and elsewhere are just tastes of what is to come in many places around the world as the water vapor levels in the atmosphere continue to climb due to anthropogenic global warming. Water vapor levels are up over the previous pre-AGW levels by about 4% now and they will get higher as the world continues to heat up.
Of course there have always been some confluences of unusual weather conditions that produced flooding. Very rarely in most places. As a result of AGW, there are going to be more such episodes of extreme weather and continuing storms that will have more water available in the air to drop, thus creating a higher incidence of major flooding events.

Flooding
(excerpts)
What the heck is it with all the floods? Just in 2007 alone, monsoons sparked catastrophic floods that displaced 10 million people in India; England and Wales saw their wettest summers ever recorded in more than two centuries of recordkeeping; China's heavy rains in early June killed 120 in flooding and landslides. And that's not all -- Mozambique, Uruguay and Sudan suffered remarkable floods, while experts warned that more extreme weather is likely to come if global warming continues unabated. The United Nations calls extreme weather a sign of global warming, and it blamed the year's record hot average global temperature for spawning flooding, deadly heat waves and wildfires. There's a 90 percent chance we'll see more frequent heavy rainfalls and heat waves this century, according to a worldwide consortium of scientists and government officials known as the Intergovernmental Panel on Climate Change. Already, it reports, "the frequency of heavy precipitation events has increased over most land areas." What gives? First, there's a simple principle. Warm air holds more moisture than colder air. So as the planet warms, more moisture is suspended in air... then periodically falls to the ground.
