Several subway lines were impacted by flooding. A photo from the 28th Street station in Manhattan showed water gushing from a drain and soaking the platform. Water was pooling on the platform at 34th Street-Penn Station, one of the city's busiest subway stops, as riders carefully maneuvered around.

Floods submerged cars and grounded planes in New Jersey, prompting the governor to declare a state of emergency. The deluge also hit New York and Pennsylvania.

Passengers on an uptown No. 1 train saw floodwaters swamping the station at 28th Street and Seventh Avenue in Manhattan.
