Three people were unaccounted for in Manitou Springs, Colorado, after an inch and a half of rain caused flash floods, the town's police chief said Saturday.

One of the missing is a petite blonde woman "seen near the creek hanging in a tree one minute and not seen the next," Police Chief Joe Ribeiro said. Two other men were also reported missing by a family member and a neighbor.

The National Weather Service say more showers and thunderstorms are expected through the weekend in states ranging from the Pacific Northwest to the deep South. In Colorado, slow-moving, heavy rain could wreak even more havoc by way of flash flooding as it falls on saturated and unstable soils in the area plagued by last year's devastating Waldo Canyon wildfire.
