Harrowing images of Northeast floods: Submerged cars, inundated neighborhoods and destroyed roads

Submerged cars, collapsed roads and streets replaced by rushing rivers were just some of the terrifying images residents in parts of the Northeast woke up to Monday after torrential rains fell Sunday — as forecasters warned people to brace for another day of downpours.

At least one person died in the severe flooding inundating parts of New England. Footage of the damage continued to emerge, showing drivers stuck on flooded streets and parts of roadways collapsed, leaving behind gaping holes.

New York's Hudson Valley was hit hard in the downpours with 8.12 inches recorded just west of the U.S. Military Academy in West Point.

A woman identified Monday as Pamela Nugent, 43, of Fort Montgomery, was swept away by rapid waters as she sought higher ground with her dog, authorities said. Officials initially said Nugent was in her 30s.

Some radar estimates showed that close to 10 inches of rain fell in the Hudson Valley near West Point, a stunning amount that is typically an entire summer's worth of rain in one day.

New York Gov. Kathy Hochul on Sunday declared a state of emergency for Orange and Ontario counties. A rare flash flood emergency was issued by the National Weather Service in New York for the lower Hudson Valley, just the second time such an alert was issued on record.

One Highland Falls resident shared a video showing the person's backyard turned into a waterfall in the deluge.

Another person in Highland Falls shared footage on Instagram showing the neighborhood street flooded and a car that was seemingly stuck. Another video showed a waterway gushing with fast-moving currents that moved onto the local streets.

The Port Jervis Fire Department, in western Orange County, shared photos showing an overturned vehicle, which was unoccupied.

In Pennsylvania, more than half a foot of rain was recorded in some areas. Reading marked its wettest July day on record Sunday with 5.35 inches of rain recorded.

A video shared by a resident of Reading showed a blue sports car being swept away in floodwaters that were as high as the wheels.

In Norfolk, Connecticut, crews were surveying roads and going door to door in impacted areas. Norfolk's public information officer Jon Barbagallo shared video showing rushing floodwaters that crumbled the pavement on Smith Road near the intersection of Route 272.

The town recorded an estimated 5 inches of rain in 90 minutes Sunday, causing numerous roads to close due to water or compromised culverts, the Norfolk Office of Emergency Management said.

As many as 14 million people are under flood alerts Monday across parts of the Northeast and New England including Hartford, Connecticut; Burlington, Vermont; and Albany, New York.

A high risk of flash flooding is in place for Vermont and areas along the New York state border Monday. A slow-moving storm system with tropical moisture is forecast to produce a large swath of 1 to 5 inches of rain in New England, as much as 8 to 12 inches in spots, and is anticipated to bring widespread flooding and damage due to already saturated soils.
