MONTGOMERY COUNTY, Md. (WJZ) — Flash flooding caused major issues during morning rush hour in Montgomery County.

More than two dozen people were rescued from floodwaters across the county Monday, most of them from vehicles.

Drivers were trapped around the region, according to Montgomery County Fire spokesman Pete Piringer.

Piringer said emergency workers responded to dozens of rescue calls and used boats to pluck people from flooded cars.

“Everywhere I turned, there was traffic and roads closed,” he said.

Piringer said he didn’t immediately receive any reports of storm-related injuries.

WUSA9 also reported that several Clarksburg area roads were also flooded.

One woman shared a video of her driving along I-66 just west of DC. The road is flooded around her and water is rushing by.

National Weather Service meteorologist Cody Ledbetter said the storm dumped about 6.3 inches of rain near Frederick, Maryland, about 4.5 inches near Arlington, Virginia, and about 3.4 inches at Ronald Reagan Washington National Airport in a two-hour period.

“The storm was not moving very quickly,” Ledbetter said.

A Potomac home also collapsed after it flooded. The collapse was caused by a mudslide.

Water gushed into the press workspace in the basement near the White House’s West Wing. Government employees worked to drain puddles of standing water with wet vacs.

Flooding led to electrical outages that closed the National Archives Building and Museum, according to a statement from the National Archives, which said the Declaration of Independence, the Constitution and the Bill of Rights were safe and not in any danger.
