"Travel will be EXTRAORDINARILY dangerous," the National Weather Service warned on Twitter. "Stay out of low areas, if in a low area that may flood, seek higher ground. Stay off the roads if at all possible. This is not the 'usual' flooding.

Pete Piringer, a spokesman for the Montgomery County Fire and Rescue Service, told WTOP that storm drains were "overwhelmed" because of the storm.

"All our folks are deployed right now," he said.

In parts of the DC region, up to four inches of rain fell in an hour, according to the Washington Post.
