New Yorkers were alerted overnight by the city's emergency management system of drenching rainfall that led to significant flash flooding.
One of the early warnings from the city to residents said, "NWS (National Weather Service) REPORTS FLASH FLOOD WARNING NOW IN EFFECT FOR ALL FIVE BOROUGHS Thunderstorms are producing heavy rain across NYC. Flash flooding is already happening or expected to begin shortly. Up to 2 more inches of rain may fall quickly."
The New York Post reported the city recorded a near-record rainfall level for a one-hour period at 2.07 inches. The result was flash flooding that impacted everything from driving on city streets to trying to manage a ride on the city subway system.
At one point after the deluge, the Post reported so much water was pouring into the 28th Street station in Manhattan that "scores" of people were trapped on the 1 train line.
The city reported, "Several subway lines were temporarily suspended or delayed due to flooding and signal issues, while portions of the FDR Drive, Cross Bronx Expressway, and Harlem River Drive experienced closures."
People living in basement apartments were warned to be ready to evacuate at a moment's notice.
The evening storm weakened by around 10 p.m. and moved on to the northeast, but left behind widespread flooding, delayed airline flights from regional airports, and many roadways were still blocked from flooding.
The New York Times reported that at least two people died in the flooding after their vehicle was carried off a roadway by rushing high water. The city reported that Central Park and Harlem both were hit with 2.64 inches of rain from the storm.
As the flooding situation began to ease in the morning hours, New Yorkers faced a high heat advisory from the National Weather Service. Heat index readings were predicted into the mid-90s for Tuesday and then reaching into the low 100s for Wednesday and Thursday.
Mayor Eric Adams issued a release telling residents that cooling centers were opening as New York faced "several days of intense heat."
