A state of emergency was declared in New Jersey due to severe flash flooding, while parts of New York City, including the subway system, were submerged by heavy rainfall.

Governor Phil Murphy urged residents to stay home, as submerged vehicles and flooded roads paralyzed districts like Somerville and Plainsville. In New York City, subway lines 1, 2, and 3 were suspended, with water pouring into stations like 23rd Street. Social media footage showed stairwells turning into waterfalls and passengers stranded in subway cars.

Floodwaters also disrupted traffic on Manhattan’s FDR Drive. Nearly 18 million people across the East Coast, including in Washington, D.C. and Baltimore, remain under flood warnings.
