Video posted to social media in the late afternoon appeared to show water levels reaching waist height at the subway station at West 157th Street in upper Manhattan.
In one video, an intrepid woman climbed down the stairs of a station and waded through the dark, murky water with a bag on her shoulder and another held above her head. In another video, a group attempted to cross the water by hopping through it in garbage bags.
The water issues weren't just below ground, either.
Some drivers on the Major Deegan Expressway in the Bronx needed emergency assistance after becoming stuck when the water got too deep on one side of the roadway.

On the other side, drivers had to pass the area only using one lane, with the others covered by brownish water.
The FDR Drive in Manhattan also had severe flooding issues in some sections.
The heavy thunderstorms came as the region was bracing itself for the arrival of Tropical Storm Elsa on Friday as it makes its way up the East Coast. The storm killed one person in Florida and created conditions that injured several others in Georgia.
