Torrential rainfall, up to 2.6 inches was observed from southeast Denver and Aurora, and extended south southwest to Castle Pines, west of Castle Rock and into Roxborough State Park. Most of the rainfall fell in less than 45 minutes. A storm drain at Quincy and Parker was clogged up by rocks that got pulled out from near the sidewalk by running water. Several cars were towed out of the flooded area. Minor flooding was reported on the Dry Creek exit of I-25 with standing water on Iliff Ave.
