Torrential rain from Hurricane Ida's remnants caused deadly flooding in parts of the Northeast and the Mid-Atlantic as the storm made its way up the East Coast on Wednesday and Thursday.

Emergencies were declared for New York state, New York City and New Jersey. In New York City, first responders rescued commuters from halted subway trains, while other travelers were stranded overnight in subway stations.

In the Philadelphia area, the Schuylkill River was almost 2 feet above major flood stage Thursday morning, swamping city streets, prompting water rescues and delaying the city's rail and bus services.

In some areas, the rainfall was unprecedented. New York's Central Park recorded its wettest hour on record, with 3.15 inches falling from 8:51 to 9:51 p.m. on Wednesday. Newark, New Jersey, received its highest one-day total on record: 8.41 inches.
