Slow moving thunderstorms produced heavy rain amounts from southwest Colorado Springs to Ramah. This rainfall occurred over already saturated ground and caused many low spots to flood. Along U.S. 24...near Ramah...the Big Sandy Creek overflowed its banks...flooding nearby pasture land. In addition to the street flooding in the Colorado Springs area...many basements and crawl spaces became flooded...which forced some residents to be evacuated due to the potential for electrical problems.
