MTA Chairman and CEO Janno Lieber is calling on New York City to build up its sewer system after massive subway flooding during Monday's storm​.

Several NYC subway stations flooded on Monday night after rain drenched parts of the city, causing severe delays and even closures.

In July 2025, footage allegedly showing flooding in a New York City subway station circulated online. One post ( archived) received more than 10.8 million views, as of this writing. The footage captured subway passengers before panning to the station outside the train, where water was flooding from a "geyser" in the floor of the station.

When the train doors opened, "quite a lot of water came in, so almost all of us stood up on the seats," a passenger told Newsweek.

After torrential rains that turned station entrances into waterfalls, the subway system will remain exposed to recurring flash flooding.

Severe flash flooding across the tri-state area on Monday caused subway delays and road closures across the Big Apple and pushed New Jersey to declare a state of emergency. All five boroughs and Nassau County are under a flash flood warning through midnight.

Republicans’ frantic project to end “woke” climate research has led them to axe funding aimed at helping mass transit cope with extreme weather events.

NYC politicians are reacting with concern, demanding that more needs to be done to keep commuters safe after several subway stations were pummeled with stormwater and sewage following Monday night’s torrential downpour.
