Gov. Kathy Hochul (D-NY) declared a state of emergency after torrential rains caused flash flooding across swathes of New York.

On Friday, heavy rainfall in New York City and the surrounding region wrought chaos, flooding streets and shutting down public transportation. In a statement, Hochul stressed that the floods were expected, and emergency personnel had been deployed beforehand to help deal with the crisis.

"I am declaring a State of Emergency in New York City, the Hudson Valley, and Long Island in response to the significant, dangerous rainfall that is currently impacting the region and is expected to continue for the next 20 hours," the New York governor said. "Ahead of this storm, we deployed thousands of State personnel, and I have directed all State agencies to provide all necessary resources to address this extreme weather event. It is critical that all New Yorkers take all necessary precautions and avoid flooded roads, which are some of the most dangerous places during flash floods."

New York residents were urged to stay home if they were able. Several major subway lines were shut down after experiencing flooding.

Videos posted on social media showed water from the flooded streets pouring down into the subway.

Other videos showed residents wading through deep water on the street, as cars struggled to get by. One resident filmed his commute, where the water had risen so high as to seep into the bus he was riding. Another filmed great quantities of water spraying through the walls of a subway, while others filmed stairwells being flooded.
