Commuters in several major cities across the Northeast and Mid-Atlantic were hampered by flash flooding after storms dumped heavy rainfall that swamped roads and knocked out power on July 14.

The storms caused flash flooding in the metropolitan areas from New York City to Washington, D.C., prompting road closures and a state of emergency declaration in New Jersey. In northern New Jersey, between 3 and 6.5 inches of rain fell, with continued flood impacts expected on July 15, the National Weather Service in Mount Holly said.

Video posted to social media showed a New York City subway station inundated with fast-moving floodwaters as passengers watched from inside a train, lifting up their feet to avoid the water rushing into the subway car. In McLean, Virginia, just outside Washington, videos showed cars stuck in floodwaters.

On July 15, parts of the Mid-Atlantic, including much of the state of Virginia, were under flood watches as forecasters warned more thunderstorms and heavy downpours were in store. The rainfall and flash flood risks to the Mid-Atlantic and Appalachian region are expected to last through mid-week, the National Weather Service said.
