Significant rainfall from storms caused flash flooding in parts of Montgomery County, Maryland, located north of Washington, D.C., on Saturday, trapping many in buildings and cars.

Storm drains along Interstate 435, a beltway that encircles most of the Kansas City metropolitan area, were unable to keep up during the deluge, he said, causing the highway to flood. Most of the rescues from vehicles took place at the highway’s 23rd St. exit, he said.

Flash flood warnings were issued for multiple areas of the metro, including Independence, Raytown, and Blue Springs.

Heavy rain overnight Thursday and into early morning Friday led to damages and road closures in Benton County.

Much of the U.S., including North Carolina, has experienced a significant increase in intense rainfall and widespread flooding throughout July, often unrelated to tropical systems and impacting areas outside designated floodplains.
