The rain has been produced by a low pressure system that has been stationed over Nevada since late Sunday, said National Weather Service meteorologist Todd Dankers in Boulder.The rain has been produced by a low pressure system that has been stationed over Nevada since late Sunday, said National Weather Service meteorologist Todd Dankers in Boulder.
The low has drawn subtropical moisture from the Mexican mainland over New Mexico and into the Rockies' foothills in Colorado — and it's been trapped by a stationary upper level ridge over the Great Plains and another system over the Great Lakes, Dankers said. The moisture becomes rain when it hits the mountains, the end result of a system he described as "a monsoon conveyer belt."

Some of the flooding was exacerbated by wildfire "burn scars" that have spawned flash floods all summer in the mountains. That was particularly true in an area scarred by fire in 2010 near the tiny community of Jamestown and another near Colorado Springs' Waldo Canyon that was hit in 2012.Some of the flooding was exacerbated by wildfire "burn scars" that have spawned flash floods all summer in the mountains.

Rain is normally soaked up by a sponge-like layer of pine needles and twigs on the forest floor. But wildfires incinerate that layer and leave a residue in the top layer of soil that sheds water. A relatively light rain can rush down charred hillsides into streambeds, picking up dirt, ash, rocks and tree limbs along the way. Narrow canyons aggravate the threat.
