One woman was rescued by a passerby when floodwater began pouring into her car near Casa Bonita. The flooding also led to a water rescue operation by West Metro Fire Rescue in Lakewood, where someone reported seeing a person in a flooded area near West 12th Avenue and Miller Street.

 But they didn't find anyone.

The National Weather Service issued a flash flood warning just after 6 p.m. It was in effect until 8:15 p.m.
