Video: Subway Lines, Roads Submerged As Flash Flood Batter New York, New Jersey

Heavy rain pummeled parts of the United States' Northeast on Monday, submerging sections of New Jersey and New York with flash flooding that inundated major roads, stranded vehicles, closed subway lines, caused long flight delays and led to the declaration of a state of emergency.

A flash flood warning was issued in parts of New Jersey, New York, Pennsylvania and surrounding areas as a slow-moving storm moved through the region. In New Jersey, Governor Phil Murphy declared a state of emergency due to flash flooding and heavy rainfall, advising people to stay indoors and avoid unnecessary travel. 

A video posted to social media showed flooding in the area bringing a major road in Scotch Plains, New Jersey, to a standstill, stranding buses.

Some subway services in America's most populous city were suspended while other lines were running with severe delays due to flooding, according to the Metropolitan Transportation Authority.

Officials in New York's Westchester County were working to rescue people whose vehicles were submerged in water, according to Carolyn Fortino, a spokesperson for the county executive.

"At this time, residents are still strongly advised to avoid all travel unless fleeing an area that is subject to flooding, or under an evacuation order," she said in an email.
