As the east coast was hit with torrential downpours on Monday morning, the region's aging infrastructure struggled to keep up.
Video posted to Twitter shows water pouring from the ceilings and down the steps into subway stations throughout New York City.
According to the New York City Subway system's official Twitter account, trains began bypassing the Bryant Park station due to excess water. Video showed water raining from the ceiling and from light fixtures.

About 100 blocks north, video showed water gushing down the stairs into a subway station at 145th and Broadway.
It's not clear if excess water caused any other delays or changes in service, including at the 145th Street station.
The city is expected to get about a quarter of an inch of rain throughout the day on Monday.
A bit further south in Philadelphia, commuters were met with walls of water pooling on freeway ramps and traffic tunnels along Interstate 76.
As the heavy rain continues across the region, we're seeing flooding. The ramp from I-476 to 76 East is closed due to floods. pic.twitter.com/dUDFkJMOMe— CBS Philly (@CBSPhilly) April 16, 2018
Rainfall was expected to total about a quarter of an inch in both New York City and Philadelphia.
